CharacteristicsThrough incessant research and development, the excellent functions of oil filled cable has beenimproved since 1924.

Among the many excellent characteristics, some typical ones can be listed as follows.

There is absolutely no void within insulation

and is stable electrically.The insulation oil, whose air bubbles and humidity are

sufficiently removed by performing degassing treatment, is

impregnated in insulating paper layer which is fully dried

under high vacuum beforehand and kept under highdegree of vacuum, and the cable is made accordingly.

Since a definite positive pressure is always kept inside of

the finished cable, there is absolutely no void in the cable

insulation.

Operating potential gradient can be large.Since no deterioration takes place in voids in the insulation

by ionizations as in the case with the solid-type cable, the

operating potential gradient can be large. Therefore, theinsulation thickness can be selected as thin.

Expansion and contraction of insulation oil

due to temperature change can be com-

pensated by the oil tanks.Expansion and contraction of insulating oil, due to change

of load under use or due to change of the external

temperature, can be fully compensated by the oil tankinstalled in a suitable position on the cable route.

Therefore, there can be no void in the insulation.

Possibility of cable self-monitoringThe inside of the cable is always kept at positive oil

pressure so that no humidity intrudes from the outside in

case damage occurs in the cable sheath, or in the joint

box. Further, in case the insulating oil leaks, the trouble is

detected earlier as the alarm device actuates and it is

possible to repair before occurrance of full-scale trouble in

the cable system.

System DesignOF cable system can be derived from economical decision and maker s engineering capability about

super high tension engineering. The reason is that many sites, around the world, have their owncharacteristics, for instances, swamp or desert, field or mountain, and inland or seaside. So pracrical routesurvey can only give precise answer just suitable to its own geographical characteristics.

We, Taihan based upon the accumulated technical know-how, have the capability to design any kindof cable system requried and install at any site under any circumstances.

By the calculation through computer, cable and accessories can be fixed to make a turn-key systemfor OF cable.

Taihan manufactures oil filled cables according to the following specification and accomplishes design and manufacture ofoil filled cables which are suitable for using conditions to meet the following requirements.

Selection of proper oil feeding system is one of the most important factors in the system design. We, Taihan OF cableengineers, will design any kind of feeding system to meet the requirement of our customer. We will install our OF cablesystem at any site whether normal or difficult.

The general principle of oil feeding system can be explained hereunder.

1) The minimum oil pressure should be above 0.2 / at any time and any position.

2) The distance necessary to feed the oil and the place to fix the oil feeding tank must be investigated first, and then thekind and volume of oil tank can be fixed.

Manufacturing Facilities andCheckpoints of Quality Control

With full automatic tension control apparatus, our paper lapping machine, made by Pirelli in Italy, can manufacture OFcable up to 345kV by a single passage

Paper lapping tension

The lapping tension of paper is calculated by acomputer which considers the type of paper, the widthof paper, and the diameter on which the paper islapped.

Humidity control

Paper lapping machines are installed in an specialcontrol room in order to keep the humidity in the room.

The room is kept at slightly higher than atmosphericpressure so that the entry of dust, litter and fineparticles of metal which are detrimental to the insulationof cable can be prevented.

Bending test immediately after paper lapping

When the leading end has passed the hauling ma-chine, a sample in the length of several meters issubjected to a bending test in order to ascertain that thecondition of paper lapping is suitable to workingstandard.

The quality of a Taihan cable starts with select-ing and using only the best raw material. Be-foreTaihan cables are manufactured the cop-per, aluminum, lead and lead alloy, paper, oil andplastic etc. are all tested in raw mate-rial form. A fully equip-ped laboratory carries outnumerous tests, physical, analytical, chemical, electrical and mechanical. And throughout themanu-facturing stages, further tests ensure that pro-duct quality is main-tained.

CablerBesides singe core, all kind of cables should be passed this machine for cabling. Smooth and clean pass lines for papercore are essential to manufacture high quality cable.

Drying TankDielectric power loss, one of the important characteristics of OF cable can be achieved by complete drying method.

Temperature control of drying tanks

The temperature of drying tank is measured at severalpoints, recorded continuously, and checked to make surethat the temperature is held within the control limit.

Temperature control of conductor during heating

During the initial hours of drying, the cable is heated by

an electric current flowing directly through its conductor,which is called the electric current drying method. In thisperiod, a program controller developed by our companycontrols the speed of temperature rise automatically andrecords the temperature.

Vacuum degree

The vacuum degree of a drying tank is measured at twopoints, recorded continuously, and checked. Vacuumpumps are in automatic operation and when somethinggoes wrong, they activate and alarm on the centralcontrol panel.

Control of drying period

The manufacturing standard specifies the period ofdrying according to the type of cable to avoid insufficientor excessive drying. ln addition to that, the drop test andleak test of drying tank utilizing the relationship betweenthe residual moisture content in paper and its equilibriumvapor pressure tell us whether or not the operation iswithin the contrl limit.

Degasifying

Before degasifying, the oil is stored in alow vacuum tank, the vacuum degreebeing monitored, as the pretreatment.During degasification, the vacuumdegree is continuously recorded, andthe rate of oil flow is automaticallycontrolled to the vacuum degree so asto obtain a uniform degasificationdegree.

After degasifying, the resistivity,

power factor, water content for all oil aremeasured. In order to reduce moistureinfiltration, the oil is held under thepressure of nitrogen during storage.

Control of vacuum degree ofcable before oil-impregnation

Usually, after the aluminum sheathcovering, vacuum degree of cables hasto be checked before being impreg-nated with oil. This period is utilized to

measure the vacuum degree of thecable just before oil-impregnation inorder to make sure the aluminumsheath is no pinhole.

Inspection of oil beforeoil-impregnation

The state of oil entering into a vacuumbottle is oberved to ascertain if the oilcontains bubbles or foreign matter. Asampling test for resistivity, powerfactor, and water content is also carriedout.

Vacuum degree control duringoil- impregnation

The vacuum degree of the cable duringoil-impregnation is measured andrecorded by a worker every two hours.Electromagnetic valves mounted on anoil-impregnating panel automaticallyclose in case of failure of power supplyor abnormally low vacuum degree, thusprotecting the cable from the entranceof air.

Completion of oil-impregnation

The judgement that oil-impregnation iscompleted is made when the oilpressure ceases to drop.

Insulating Oil Degasifier and Impregnating PanelThis equipments can degas and refine the insulating oil, alkylbenzene type synthetic oil,to give and excellent insulating stability for cable.

Affer vacuum sheath process, degassed and refined oil can be put into cable.

Vacuum Sheathing EquipmentTo withstand inner oil pressure and prevent outer mechanical shock, OF cable should be made with metallic layer. Tomaintain the low moisture contents of dried insulation paper while sheathing metal layer, OF cable should be made underthe vacuum continuously.

The manufacturing condition for Aluminum Press and Lead Extruder is almost same. For instance, working condition ofaluminum press is as follows.

Machine for Reinforced TapesAfter lead sheathing, non-magnetic tapes for example stainless tape, will be wrapped on the lead sheath to reinforce thecreep characteristics.

PE/PVC ExtruderAs an anti-corrosion protection, in many cases underground cable is used with plastic outer sheathes.

Vacuum sheathing

After the completion of drying, the cable is covered withan aluminum sheath while still being held in high vacuumdegree. Throughout this process, the vacuum degree inthe cable is monitored and recorded continuously, andany abnormality in vacuum degree triggers and alarm.

Automatic operationThe aluminum press has fully automatic operation toavoid human error and to obtain stablized quality.

Temperature control

The temperatures of the die-block, the ingot heatingfurnace, and ingots are continuously recorded forconsistent operation.

Surface inspection

As the metallic sheath is one of the vital parts of oil filledcables, its surface is inspected continuously in order toconfirm that surface damage, pinhole, and other defectsdo not exist.

Accessories

Sealing Ends

Indoor and outdoor sealing end (EB-A)

Sealing end is sends and takes electric power into and

out of cable. Porcelain bushings are needed to be

insulated between the earth potential parts and the high

voltage parts, and this sealing end has stress relief cone

formed of wide paper or a condenser cone formed of

insulating paper layers and metal foil for inside

reinforcement according to the voltage uesd. Connector

is fastened to the cable conductor by compression

method and a flexible terminal lug is placed between theconductor and the lead wire to avoid applying

unnecessary external force against the sealing end.

SF6 gas immersed sealing end (EB-G)Sealing end is used for terminating the cable for the

SF6 gas switch gear. Epoxy bushings are needed to

be insulated between the earth potential parts and the

high voltage parts. The inner construction of this

sealing end is similar to that of an indoor and outdoor

sealing end except that the sealing end is completely

enclosed and immersed in gas to the higher

insulat ion strength and to prevent dust from

collecting, etc.

Oil immersed type sealing end (EBO)This construction of this sealing end is similar to the of an

indoor and outdoor sealing end except that the sealingend is completely enclosed and immersed in oil to preventdust from collecting, and the size of EB-O is much smallerthan the one of EB-A, this type of sealing end is forconnecting cable with transformer

Joint Box

Straight through joint (NJ)This joint is used for jointing cables, and electrical jointingand oil passage are part of its function or structure. And

this joint has same quality as, or better than cable itself,and is free from any electrical and mechanical defects dueto the trouble developed by the power transmissionsystem.

Insulation joint (IJ)The structure of this joint is almost same as straightthrough joint box, and the difference between them is toput an insulator flange at the center of copper casing.

This box is used for jointing cables and at the sametime for insulating on metal sheath from the other metalsheath to get a sheath voltage reducing under safetylevel.

Oil stop joint (SJ)This joint is used for dividing the oil feeding section incase that route length is too long or oil pressure changeis too excessive at static or transient operation. Alsothis joint is used for connecting the cables electrically,and at any time for stopping the oil passage to separatethe oil feeding section of both cables.

Oil feeding tank

The inner oil of oil filled cables expands or shrinks automatically, and enough oil has to be kept in the oil feeding tank tosupply oil to the cables for a significant length of time even if the oil should be out. There are many kinds of oil feedingtanks, for example, pressure tank(inner and outer gas type) and special oil feeding tank, etc.

Valve panel

The valve panel(guage panel) shall be installed at the intermediate of

pressure tank and sealing end or oil stop joint and have such a function

as to sense and indicate the oil pressure. If necessary, the pressure

guage shall be provided with the electrical contacts which shall make the

electric cirucit for the oil pressure alarm.

Other Accessories

Cross bond link boxThe cross bonding link box shall be used for connecting the bonding

wire properly and be provided with surge diverters to discharge at the

suitable for installation in joint handholes and manholes and be fully

watertight.

Alarm deviceIt is advisable to have an alarm device to notify the guard when the

cables are out of order or damaged.Usually a transmitter is located at the oil tank and a receiver is placed in the control room. We manufacture three

kinds of alarm devices; one alarm device operates when the minimum pressure or volume is reached. Another

continuously indicates the pressure or volume, and the third has an indicator and a recorder. The proper one should be

chosen after duly considering the functional importance of the cable and the maintenance system adopted for the line.

Oil feeding pipeThe oil feeding pipes used for connecting the cables to the oil tank lead are made of armored lead, copper and etc. We

will choose the most suitable one for your particular system.

Terminal box for control cableThe alarm transmitter and receiver are connected with control cables. Since many alarm transmitters are generally

used, this terminal box is placed near the transmitters to allow the circuits to be opened or checked.

Installation

Direct BurialWhere the road is narrow, the construction of conduitunder the road is usually not permitted.

Where the number of cables is few and no futureincrease is expected.

Where the road digging is easy.

Underground DuctIn case of a main underground transmission line wherethe number of cables are many or expected to beincreased in near future.

In case of hard pavement or where hard pavement willbe constructed in future.

Where digging is difficult due to heavy traffic.

Special LayingIn case cables are installed in special places where thereare bridges or railways, special laying methods areemployed as follows ;

When a cable crosses a river or canal, cables areattached to the bridge. If there is no suitable bridge in theneighborhood, an exclusive bridge should be buit or amethod of submarine laying should be adopted.

As long as the strengh and space of the bridgepermits, it is best to attach the cables to the bridge.Whether it is better to build an exclusive bridge or to laysubmarine cable depends on the cost and difficulty ofconstruction.

In case of crossing a railway, there are two methods; oneis digging through the railway bed, and the other ispiercing from the side of the railway by using anexcavator. When the cable crosses many tracks like asurface from railroad or suburban railway, digging therailway bed is usually adopted. Except for the above

case, piercing by using an excavator is adopted.

Taihan has many achievements and excellent techniques, relative to cable installation work andis making performance doubly sure in regard to safety of operations, besides vigorouslypromoting development, rationalization and speedy installation. And also Taihan is performing itswork consistently, from planning to testing after installation, including laying of oil filled cables,sealing ends assembly, construction of joints, and oil feeding equipment. There are the followingmethods in laying of oil filled cables and special features are as follows.
