along with the copy of the concluded agreement.

The Contractor is required to carry out the detailed survey of the route of the line and fix up the

locations at the average span indicated in the schedule and mark the locations and submit a detailed

route map to the Engineer in charge of the work within 30 days for approval. In the course of

surveying by the contractor, any conspicuous variations in the change and physical feature to those

indicated in the route map and as actually existing are noticed, the deviations must be brought to

the notice of the APDCL Engineer. The APDCL Engineer if considered necessary shall make

alterations, which shall be carried out accordingly and the APDCL after inspecting the surveyed route

and the revised route map shall be given for final approval in writing. The contractor shall not

commence the work until the final approval of the route map is given by the Engineer in charge in

writing to the contractor.

1.4 WAY LEAVES AND TREE CUTTINGS

Proposals for way leaves and right of way shall be submitted by the contractor. Permission will be

obtained by the APDCL within reasonable time for which due notice shall be given by the Contractor.

The Contractor shall arrange for tree cutting or tree branches cutting also.

The widths of tree clearance to be adopted for lines of various voltages are as detailed below:

a. 33 KV LINE (Trunk Line) All growth within 6.096 M (20 ft) from the center line of support and all trees which may fall and

foul the line.

b. The Contractor shall take all possible steps to see that standing crops, etc. are not damaged while attending to tree cutting. When such damage is inevitable the compensation will be borne by the APDCL provided the damage is with the prior concurrence of the Engineer. The Contractor shall bear the compensation for damage caused by the gangs without prior concurrence of the Engineer concerned.

c. No trees shall be cut until the APDCL has made necessary arrangement with the authorities concerned and permission is given to the Contractor to fell such trees. The contractor shall arrange to remove the obstacles as soon as possible.

d. At such times, when it may not possible for APDCL, to arrange right-of-way for excavation of pole pits or erecting the poles of stringing the line, then at all such times, the contractor shall shift his gangs to other areas. The rates quoted shall cover all such contingencies and no extra payments shall be claimed for such contingencies.

1.3 EXCAVATION OF POLE PITS, STAY PITS AND D.P. PITS a. After the final survey of the line and after marking the pole locations with pegs, excavation work

has to be commenced in accordance to the approved route map. Excavation is generally done by pick axes, crow V-bars and showers although some times earth augers are used. Excavation of pole pits in very hard or rocky soil or in rock beds, may involve blasting with suitable explosives. The pits for the supports are excavated in the direction of the line as this will facilitate the erection of support are excavated in the direction of the line as this will facilitate the erection of support, in addition to giving greater lateral stability, the depth of the foundation to be

P a g e |

excavated for poles shall be in accordance with relevant sketch for the erection of pole or stay of D.P. etc.

1.4 ERECTION OF POLES : a. PSC POLE :

PSC poles should be erected perpendicular to ground level including excavation of earth pit

having depth equal to 1/5 th the length of pole and cross-section 75 cm x 50 cm as directed by

department including dragging and carrying of pole to site as per soil condition as given below.

(i) earth filling with soil at bottom and surrounding with vigorous ramming;

(ii) earth filling with soil at bottom and surrounding with vigorous with boulder packing including

supply of boulder by contractor ( size of boulder 150mm x 200mm);

(iii) grouting and mufflering in proportion 1:2:4 RCC foundation and filling of cement concrete as

per specification including supply of cement , stone chips, shuttering etc. as directed ]

b. POLE CLAMP: The pole clamp is to be made of MS flat of size 40 mm x 6 mm with necessary drilling of holes

and painting with primer and anti corrosive paint suitable for different size of steel tubular pole

and PSC pole.

1.5 ERECTION OF SUPPORTS After the excavation of pits is completed the supports to be erected may be brought to the pits

location. Then the pole may be erected inside the pit. Wooden support may be utilized to

facilitate lifting of the pole at the pit locations.

Before the pole is put into pit, RCC padding may be laid below the pole to increase the surface

contact between the pole and the soil. The padding will distribute the weight of the pole

uniformly on the soil.

Having lifted the pole, the same should be kept in a vertical position with the help of manila rope

of 25 mm dia using the rope as a temporary anchor.

As the poles are being erected say from the pole already erected to the next location where the

pole is being erected, the alignment of the poles are to be checked and set right by visual check.

The verticality’s of the poles are to be checked with a spirit level on both transverse and

longitudinal directions.

Having satisfied that the verticality and alignment are all right, earth filling or concreting is to be

done.

In swampy and special locations, however, before earth filing, the poles are to be concreted up to

ground level of the pit.

After the poles have been set the temporary anchors are to be removed. The supports shall be

buried to a depth as per REC construction standard.

P a g e |

1.6 ERECTION OF D.P. STRUCTURES FOR ANGLE LOCATIONS (FOR 11 KV LINES) Generally, for angles of deviation more than 20° double pole structures of spacing 1.2 mts (4.0 ft)

may be erected. The pits are to be excavated as per bisection of the angle of deviation.

After the poles are erected, the horizontal / cross bracing should be fitted and the supports held in a

vertical position with the help of temporary guys of manila rope of at least 25 mm dia. Ensuring that

the poles are held in a vertical position (this can be checked with a spirit level) the concreting of the

poles with cement, granite chips of size 20/30 mm mesh and sand in the ratio M400 conforming to

ISS is to be done from the bottom of the support to the ground level. Before lifting the pole in the

pit, concrete padding of not less than 75 mm thickness may be put for the distribution of the load of

the support on the soil.

After the concreting is done, the pit may be filled with earth after curing of the concrete is

completed.

Four stays along the line, two in each direction and two stays along the bisection of angle of

deviation are to be provided.

Stay concreting may be done with M 400 concrete mixture

The D.P. shall be erected as per the approved drawing.

1.7 ANCHORING AND PROVIDING GUYS FOR SUPPORTS Fitting of stay set on overhead line including digging of earth pit of area 90cm x 60 cm and depth of

1.4 m placing the stay rod with G.I stay wire Guy insulator on pole clamp , fixing of thimble bow etc

with hard soil packing and ramming to fill up pit to ground level.

Guys are to be provided to the supports at the following places (i) Angle locations, (ii) Dead end

locations, (iii) Tee-off points, (iv) Steep gradient locations to avoid uplifted on the poles.

The installation of guy will involve the following works:

i) Excavation of pit and fixing of stay rod. ii) Fastening guy wire to the support. iii) Tightening guy wire and fastening to the anchor

The marking of the guy pit for excavation, the excavation of pits and setting of the anchor rod must

be carefully carried out. The stay rod should be placed in the position such that the angle of

inclination of the rod with the vertical face of the point is 30°/45° as the case may be. The concreting

of the stay at the bottom should then be carried out. The back filling and ramming must be well done

thereafter, and allowed to set for at least 7 days. The free end of the guy wire is passed through the

eye of the anchor rod, bent back parallel to the main portion of the guy and bound after inserting

the G.I. Thimble. The loop is protected by the G.I. Thimble, where it bears on the anchor rod. Where

the existence of guy wire proves hazardous, it should be protected with suitable asbestos pipe, filled

with concrete of about 2 mts length above the ground level, duly painted with white and black stripe

so that it may be visible at night. The turn buckle shall be mounted at the pole end of the stay and

guy wire so fixed that the eye bolt turn buckle is half way in the working position, thus giving the

maximum movement for tightening or loosening.

P a g e |

Guy insulators are placed to prevent the lower part of the guy from becoming electrically energized

by a contact of the guy when the conductors snap and fall on them of due leakage. No guy insulator

shall be located less than 2.6 mts. from the ground.

The anchoring and providing guys for supports (Single guy Bow guy fly guy) shall be done as per

sketch enclosed. Bow guy and fly guy shall be provided as per field conditions.

1.8 FIXING OF CROSS ARMS INSULATORS

After the erection of supports and providing guys, the next step would be to mount the cross arms on

the support erected. The lineman should climb the support having requisite tools with him and the

cross arm is then tied to a hand line and pulled up by the ground man and should station himself well

to one side so that if any material drops from the top of the pole it may not strike him. All the

materials required should be lifted or lowered by means of the hand line. In no case, the materials of

the tools should be dropped or thrown from the pole top.

The fixing of 33 KV Cross arms shall be in accordance to spacing detailed in Sketch. G.I. bolts and nuts

and spring washers of good quality only shall be used which will have to be procured by the

contractor.

1.9 Back Clamps

The back clamps for fixing of the seating channels, “V” cross arms, horizontal cross arms and top

cleats will have to be procured by the contractor and shall be in accordance with sketch enclosed

and the clamp shall be fabricated with 75 X 8 mm M.S. Flat for 33 KV

2.0 Top Cleats

The top cleats shall be got fabricated with M.S. Channel of size 75 X 40 mm for 33 KV and shall be in

accordance with REC construction standard.

2.1 INSULATORS

P a g e |

The pins for insulators shall be fixed in the holes provided in the cross arms and the pole top

brackets. The insulators shall be mounted in their places over pins and tightened. In the case of

strain or angles supports, where strain fittings are provided for this purpose, one strap of the strain

fitting is placed over the cross arm before placing the bolts in the hole of the cross arms. The nut of

the strap is so tightened that the strap can move freely in horizontal direction, as this is necessary to

fix the strain insulator.

The insulator shall be cleaned and examined for defects before fixing, it shall be ensured that all the

current carrying parts are smooth and without dirt, cracks or chips.

2.2 STRINGING OF THE LINE CONDUCTORS

For the guidance of the contractor certain do’s and don’ts are given below before the workmen

actually commence the stringing work.

a. Do’s and Don’ts DO’s

i. Use proper equipment for handling aluminum conductors at all times. ii. Use skids, or similar method for lowering reels or coils from transport or

ground. iii. Examine reel before unreeling for presence of nails or any other object, which

might damage the conductor. iv. Rotate the reel or coil while unwinding conductor. v. Grip all strands while pulling out the conductor. vi. Control the unreeling speed with suitable braking arrangement. vii. Use wooden guards of suitable braking arrangement. viii. Use long straight, parallel jaw grip with suitable liners when pulling conductor

thus avoiding nicking or kinking of the conductor. ix. Use free running sleeves or blocks with adequate grooves for drawing/paving

conductors. x. Use proper sag charts. xi. Mark conductors with crayons or adhesive tape of such (other) material, which

will not damage the strand. xii. Make all splicing with the proper tools. xiii. Use a twisting wrench for twisting the joints. xiv. Chromite or graphite conducting oxide-inhibiting grease should be used before

cleaning with wire brush. DON’Ts

i. Do not handle conductors without proper tools at any stage. ii. Do not pull conductors without ensuring that there are no obstructions on the

ground.

P a g e |

iii. Do not pull out excess quantity of conductor than is required. iv. Do not make jumper connections on dirty or weathered conductor. v. Do not handle aluminum conductors in a rough fashion but handle it with care

it deserves. b. Conductor erections

The erection of overhead line conductor is a very important phase in construction. The erection

of conductors can be sub-divided into 4 separate parts as follows:

i. Transport of conductors to work site. ii. Paving and stringing of conductors. iii. Tensioning and sagging of conductors. iv. Joining of conductors. At the important crossing of roads, canals, navigable rivers, railways etc., flagmen should be in

attendance to ensure that normal services are not unduly interrupted. These crossing should only

be carried out in conjunction with and with the approval of the proper authorities concerned.

The conductor drums shall be transported to the tension point without injuring the conductor, if,

it is necessary to roll the drum on the ground for a small distance, it should be slowly rolled in the

direction of the marked on the drum. The drum should be so supported that it can be rotated

freely. For this purpose the drum should either be mounted on the cable drum supports of jacks

or hung by means of chain pulley of suitable capacity, suspended from a tripod. In case if it is not

possible to raise the conductor drum by any of the above method, a trench of suitable depth

slightly bigger than the conductor drum may be dug, so as to facilitate free rotation of the cable

drum when it is suspended in the trench by means of M.S. Shaft. While paving, care should be

taken to see that conductor does not rub against any metallic fitting of the pole or on the

bad/rocky ground. Wooden trusses should be used for this purpose to support the conductor.

The conductor should be passed over the poles on wooden or aluminum snatch pulley blocks

provided with low friction bearings. While conductor is being paved out slowly, some braking

arrangement should be made so that the rotation of the drum may be stopped in emergency.

In case the length of one piece of the conductor is less than the length of the section in which

conductor paving is being done, it is easy to stretch one length of all phases from one end the

remaining length from another end of the section any part of the conductor shall be left at a

height of less than that of 5 meters, above the ground by rough sagging.

c. Mid Span Jointing of Conductors The mid span jointing of conductors can be carried by twisting the joint at the ends and the wire

should project a few centimeter, beyond the end of the sleeves. The projected wires are given a

sharp bend to keep them from slipping out of the sleeve. The end of the sleeves are then held

tightly by twisting wrenches and then 4 to 5 turns in one direction generally anti-clock wise

direction. Crimping Tools are preferably to be used for joints and jumpers.

d. Sagging and tensioning On the completion of the paving of the conductors and making mid span joints if any, tensioning

operations will commence. Temporary guys will have to be provided for both the anchoring

supports in the section where the stringing has to be done. At the tensioning end, one of the

conductors is pulled manually up to a certain point and then come along clamp is fixed to the

conductor to be tensioned. The grip to the come along clamp is attached to double sleeve pulley

block or the pulley lift machine and gradually tensioned.

P a g e |

The conductor should then be sagged in accordance with the sag temperature chart for the

particular conductor and span. The sag should then be adjusted in the middle span of the section.

The sag chart is to be provided. The stretch of the conductor has to be taken out before stringing

in order to avoid the gradual increase in sag due to the setting down of the individual wires.

There are ways of accomplishing this:

a) Pre-stressing In this method the conductor is pulled up to tension considerably above the correct figures, but

never exceeding 50% of breaking load for a short period of say twenty minutes. As this method

requires more time and involves the use of stronger tackle to secure the higher tension the other

method of over tensioning is commonly adopted.

b) Over-tensioning This method consists of pulling up the conductor to a tension a little above the theoretical

tension for prevailing temperature and fixed it up at that tension with correspondingly reduced

sag. After a certain time the conductor will settle down to the correct sag and tension. A tension

of five to eight percent more than the theoretical value has been found to be suitable for the

sizes of ACSR and AAAC conductors standardized by REC. The ambient temperature during

sagging may be recorded correctly.

Conductors can be sagged correctly only when the tension is the same in each span throughout

the entire length of section. Use of snatch blocks reduces the friction and chances of inequality of

tension in various spans.

Sagging can be accomplished by several different methods but most commonly used method is

“Slighting”. The slighting sag method of measuring sag is by the use of targets placed on the

supports below the cross arms. The targets may be light strip of wood clamped to the pole at a

distance equal to the sag below the conductor when the conductor is placed in snatch block. The

lineman sees the sag from the next pole. The tension of the conductor is then reduced or

increased, until the lowest part of the conductor in the span coincides with the lineman’s line of

sight.

When sagging is completed, the tension clamps shall be fixed. The clamp can be fitted on the

conductor without releasing the tension. A mark is made on the conductor at a distance from the

cross-arm equal to the length of complete strain insulator. Before the insulator set is raised to

position, all nuts should be free. Come along clamp is placed on the conductor beyond the

conductor clamp and attached to the pulling unit. The conductor is pulled in sufficiently to allow

the insulator assembly to be fitted to the clamp. After the conductor is clamped to insulator,

assembly unit may be released gradually.

If the tension is released with a jerk, an abnormal stress may be transferred to conductor and

support, which may result in the failure of the cross arm, stay or pole in some cases. After the

stringing is completed, all poles, cross arms, insulators, fittings etc. are checked upto ensure that

there have been no deformities etc.

The next step is to place the conductor on the top of the pin insulator from the snatch block and

removing snatch blocks. Conductors are then fastened to insulator by the use of aluminum wires.

The following points should be observed:

P a g e |

i) Proper size of the tie binding wire which can be readily handled and with adequate strength is to be used.

ii) The length of tie wire should be sufficiently long for making complete tie including the end allowances for gripping with ends.

iii) A good tie should provide a secure binding between the line conductor and insulator and should reinforce the conductor on either side of the insulator.

iv) The use of cutting pliers for binding the tie wire should be avoided. v) The tie wire which has been used previously should be reused

Before tying the conductor to the insulator two layers of Aluminum tapes should be wrapped

over the conductor in the portion where it touches the insulator. The width and thickness of

aluminum tape to be used for a specific size of conductors has been specified in hand books of

aluminum conductor manufacturers and the same be referred to. The Aluminum tapes should

also be used at the tension clamp and for proper grip.

Normally in straight runs of line, the conductors are run on the top of insulators. When there is

small of deviation the conductor is placed inside groove and bound. Accordingly, there are two

methods of tying the conductors to insulators. The binding wire/tie wire has to be procured by

the contractor and the bid price shall include the cost of this.

The contractor shall be entirely responsible for any damage to the supports, other accessories

and conductor. He shall also be responsible for proper distribution of the conductor drums to

keep number and lengths of cut pieces of the conductor to a minimum.

e. Conductor damage and repair If the conductor is damaged for whatever reasons, and damage is not repaired by aluminum

sleeves, etc., it shall be brought to the notice of the Engineer and shall not be used without his

approval. Even repairing of conductor surfaces shall be done only in case of minor damages, scuff

marks etc., which are safe from both electrical and mechanical points of view. The final;

conductor surface shall be clean, smooth, without any projection sharp points, cut or abrasion

etc. giving satisfactory corona and R.I. performance.

No joints or splice be made in span’s crossing over main roads, railways, small rivers or intension

spans. Not more than one joint per conductor shall be allowed in one span. The strength of the

joint shall conform to IE Rule 75.

f. Stringing. Whatever necessary ground clearances have to be measured to ensure obtaining adequate line

clearance as per IE Rule 77 (i)

GUARDING :

When an overhead line crosses or is in proximity of any telecommunication line arrangement shall be made to provide protective device or guarding.

When an overhead line crosses or is in proximity of to another over head line or overhead lines of different voltage on same supporting structure guarding arrangement shall be provided so as to guard against the possibility of their coming into contact with each other.

Every guard-wire shall be an actual breaking strength of not less than 635 kg and if made of iron or steel shall be galvanize.

maintained in position during manufacture. The un-tensioned reinforcement, as indicated in the

drawings, should be held in position by the use of stirrups which should go round all the wires.

AII wires shall be accurately stretched with uniform pre-stress in each wire. Each wire or a group

of wires shall be anchored positively during casing. Care should be taken to see that the

anchorages do not yield before the concrete attains the necessary strength.

13.0 Cover

The cover of concrete measured from the outside of pre-stressing tendon shall be normally 20 Nm.

14.0 Welding and Lapping of Steel

The high tensile steel wire shall be continuous over the entire length of the tendon. Welding shall

15.0 Compacting Concrete shall be compacted by spinning, vibrating, shocking or other suitable mechanical means.

Hand compaction shall not be permitted.

16.0 Curing The concrete shall be covered with a layer of sacking, canvass, Hessian or similar absorbent

material and kept constantly wet up to the time when the strength of concrete is at least equal to

the minimum strength of concrete at transfer of pre-stress. Thereafter, the pole may be removed

from the mould and watered at intervals to prevent surface cracking of the unit, the interval

should depend on the atmospheric humidity and temperature.

The pre-stressing wires shall be detensioned only after the concrete has attained the specified

strength at transfer (i.e., 200 or 210 kg/cm2 as applicable). The cubes cast for the purpose of

determining the strength at transfer should be cured, as far as possible, under conditions similar to

those under which the poles are cured. The transfer stage shall be determined based on the daily

tests carried out on concrete cubes till the specified strength indicated above is reached.

Thereafter the test on concrete shall be carried out as detailed in IS: 1343 (Code of practice for

pre-stressed concrete). The manufacturer shall supply, when required by the owner or his

representative, result of compressive test conducted in accordance with IS: 456 (Code of practice

for plain and reinforced concrete) on concrete cubes made from the concrete used for the poles. If

the owner so desired, the manufacturer shall supply cubes for test purposes and such cubes shall

be tested in accordance with IS: 456 (Code of practice for plain and reinforced concrete).

P a g e |

The detensioning shall be done by slowly releasing the wires, without imparting shock or sudden

load to the poles. The rate of detensioning may be controlled by any suitable means either

mechanical (screw type) or hydraulic.

The poles shall not be detensioned or released by cutting the pre-stressing wires using flames or

bar croppers while the wires are still under tension.

Separate eye-hooks or holes shall be provided for handling the transport, one each at a distance of

0.15 times the overall length, from either end of the pole. Eye-hooks, if provided, should be

properly anchored and should be on the face that has the shorter dimension of the cross-section.

Holes, if provided for lifting purposes, should be perpendicular to the broad face of the pole.

Stacking should be done in such a manner that the broad side of the pole is vertical. Each tier in

the stack should be supported on timber sleeper located as 0.15 times the overall length,

measured from the end. The timber supported in the stack should be aligned in a vertical line.

Poles should be transported with their broad faces placed vertically and, in such a manner that the

shocks are avoided. Supports should be so arranged that they are located approximately at a

distance equal to 0.15 times the overall length from the ends. The erection of the pole should be

carried out in such a way that the erection loads are applied so as to cause moment with respect to

the major axis, i.e., the rope used for hoisting the pole should be parallel to the broader face of

the pole.

17.0 Earthing

17.1 Earthing shall be provided by having length of 8 SWG GI wire embedded in concrete during

manufacture and the ends of the wires left projecting from the pole to a length of 100 mm at 250

mm from top and 150 mm below ground level.

17.2 Earth wire shall not be allowed to come in contract with the pre-stressing wires.

17.3 Tests

18.0 Transverse Strength Test

Poles made from ordinary Portland cement shall be tested only on the completion of 28 days and

poles made from rapid hardening cement only on the completion of 14 days, after the day of

manufacture.

The poles may be tested in either horizontal or vertical position. If tested in horizontal position,

provisions shall be made to compensate for the overhanging weight of the pole, for this purposed,

the overhanging portion of the pole may be supported on a movable trolley or similar device.

The pole shall be rigidly supported at the butt end for a distance equal to the agreed depth of

planting.

Load shall be applied at a point 600 mm from the top of the pole and shall be steadily and

gradually increased to the design value of the transverse load at first crack. The deflection at this

load shall be measured.

A pre-stressed concrete pole shall be deemed not to have passed the test if visible cracks appear at

a stage prior to the application of the design transverse load for the first crack.

The load then be reduced to zero and increased gradually to a load equal to the first crack load plus

10% of the minimum ultimate transverse load, and held up for 2 minutes. This procedure shall be

repeated until the load reaches the value of 80 per cent of the minimum ultimate transverse load

and thereafter increased by 5 per cent of the minimum ultimate transverse load until failure occurs.

Each time the load is applied, it shall be held for 2 minutes. The load applied to pre-stressed

concrete pole at the point of failure shall be measured to the nearest five Kilograms.

The pole shall be deemed not to have passed the test if the observed ultimate transverse load is

less than the design ultimate transverse load.

19.0 Measurement of Cover

After completion of the transverse strength test, the sample pole shall be taken and checked for

cover. The cover of the pole shall be measured at 3 points, one within 1.8 meter from the butt end

of the pole. the ·second within 0.6 meters from the top and the third at an intermediate point and

the mean value compared with the specified value.

The mean value of the measured cover should not differ by more than (±) 1 mrn from the specified

cover. The individual values should not differ by more than (±) 3 mm from the specified value.

If these requirements are not met, the workmanship with reference to aligning of the end plates

and pre-stressing wires and assembly of moulds should be improved and inspection at pre-

production stage tightened suitably.

P a g e |

20.0 Marking

The pole shall be clearly and indelibly marked with the following particulars either during or after

manufacture but before testing at a position so as to be easily read after erection in position.

a) Month and year of manufacture

b) Transverse strength of pole in Kg

c) Maker's serial No and mark and Project .

21.0 Inspection

Inspection may be carried out by the purchaser or third party nominee at any stage of manufacture.

The supplier shall grant free access to the purchaser's representative or third party nominee at a

reasonable time when the work is in progress. Inspection and acceptance of any equipment under

this specification by the purchaser shall not relieve the supplier of his obligation of furnishing

equipment in accordance with the specification and shall not prevent subsequent rejection if the

equipment is found defective.
