These Installation instructions are general and do not cover all contingencies.

CAUTIONThe equipment covered by this document is intended to be installed, operated and maintained byqualified persons who are trained in the installation, operation and maintenance of electric power

transmission equipment along with the associated hazards.It is assumed the jointing crew is experienced and has been trained in installation of these or similar

terminations.Carelessness, improper handling of materials, tools or equipment or performing unauthorized

procedures during installation would seriously affect the operational characteristics of the

termination.

The cable and termination components have to be protected from dust, contamination and moisture.

A light structure built around the cable end will provide this protection. If required a space heater ordehumidifier needs to be used to provide comfortable work conditions and prevent moisture

condensation on the cable from breath in cold weather and sweat in warm weather.Cleanliness is essential. Make sure that the tools, components, work area and jointers hands and

clothing are kept as clean as possible during installation.

Storage:Store terminations in shipping crates, indoors.

2. PREPARATORY STEPS

Check the markings on the shipping crate. Verify that the termination type and the stress cone sizeare proper for the cable. Inspect the crate for any damage during transportation. Check the contents

against bill of material attached to these installation instructions . Inspect the parts for any damageduring transportation.

Have all required tools at hand. See attached list of typical splicing tools and materials. Make sure

the crimp dies are proper for the connector.

WARNING

Make sure the cables are de-energized, grounded and properly phased. Not doing so may result in

injury or death to personnel.

Verify support structure is level, has proper bolt hole pattern for installation of mounting plate (foroutdoor terminations) or interface plate (for GIS and oil immersed terminations), and has minimum

opening to fit entrance housing as shown on G&W Termination assembly drawing (for Outdoorterminations).

Ensure there are provisions to secure the cable to the support structure below the terminationmounting surface.

FOR GIS AND OIL IMMERSED TERMINATION:

-Check proper location of cable(s) and interface by temporarily assembling interface plate or SF6

enclosure in the final installed position and making adjustments prior to installation of termination.-Provided oil needs to be heated to 60C prior to filling the termination.

FOR CABLES WITH XLPE INSULATION:

Straightencable end according to cable manufacturer's recommendations. For this operation cable

is cut approximately 200 mm (8") longer than shown in Section 3. General practice is to heat thecable using temperature controlled heating tapes or blanket, with sufficient cushion between the

tapes and cable, at approximately 80C for four to six hours. Tapes or blankets are removed afterheating and cable is positioned between two straight angle irons (or boards) and loosely installed,

for cooling and straightening.

CAUTIONExercise extreme caution if heaters with thermostats are used since thermostat malfunction can

damage cable ends. Self temperature controlled blankets are available.

Typically cables with screen wires or cables with corrugated metallic sheaths are annealed after

removal of the jacket and sheath. The cables with lead sheath and/or metallic tapes can be annealed

before removal of the metallic sheath or in case of a thin jacket before removal of the jacket. It isupon supervising engineer to decide how and when to start annealing the cable.

6. CABLE INSULATION PREPARATION (XLPE insulation)

1. Straighten the cable and mark cable insulation screen at the distance M from the top of the

connector as shown in Figure 6.1. For 138 kV outdoor terminations "M"= 1457 3 mm (57-3/8"

1/8").

2. Remove the semi-con insulation screen from the pencil area at the connector to this point. Aspecial stripping tool or glass can be used.

If stripping tool is used adjust the depth of the cutting blade so approximately 75% of cableinsulation is exposed on the circumference of the cable. Remove all remaining insulation semi-con

screen with glass NOT with sand paper. Exercise caution. Avoid nicks or gouges on the cable

insulation surface.Follow cable manufacturers recommended procedure for removing strippable semi-con insulation

screen.

3. Pencil the screen approximately 20 mm (3/4) using glass.

CAUTION

The transition between cable insulation and insulation screen must be smooth. Do not

cut into insulation. Such a damage to cable insulation can cause cable failure.

Figure 6.1: Cable Insulation Screen Removal

4. Before start of sanding operation apply 3 half lapped layers of PVC tape on the transitionbetween cable insulation and semi-con screen covering the penciled area of semi-con screen. This

will avoid imbedding conductive particles from the screen into cable insulation during sanding.

5. Use No. 80 grit sand paper to smoothen the cable insulation. Continue insulation sanding

with No. 150 grit paper. Be sure that all nicks, gouges and scratches are removed from cableinsulation. Polish the cable insulation using No. 240 grit paper. For 230 kV cable terminations, use

No. 320 grit paper for final polishing. A higher polish is achieved at the finish by reversing thesanding cloth and polishing the insulation.


11/21

GWI 36D-47

Page 10 of 20

CAUTION

Do not smudge cable semi-con onto the cable insulation. Make sure there is no trace

of cable semi-con on exposed cable insulation. That can cause cable failure.

6. Remove PVC tape from the cable screen and temporarily apply two layers of PVC tape over100 mm (4) long section of the insulation at the edge of the semi con screen. Carefully sand the

penciled area only with 240 grit sand paper. Remove temporarily applied PVC tape.It is imperative that the transition between semi-con insulation screen and insulation be smooth and

free of any scratches and foreign material.

CAUTION

Make sure that sand paper is applied on the cable semi-con screen only on the

penciled area (approx. 20 mm (3/4)). Do not sand cable semi-con screen furtherdown that point. This can cause cable failure.

The cable should be wiped periodically with new, dry, lint free cloth dampened with solvent to

remove any foreign matter imbedded in the insulation. Wipe the cable thoroughly clean. Wipingshould always be done towards the cable semi-conductive insulation screen to prevent wiping semi-

con particles onto the insulation. Do not use a cleaning cloth twice; always discards cloths after first

pass. If solvent with long evaporation time is used, wipe the cable dry with a clean, lint-free, drycloth immediately after cleaning.

7. Measure cable insulation outer diameter.

CAUTION

Verify that insulation outer diameter falls into the range indicated on the label on thestress cone shipping package. Do not use the stress cone if the insulation diameter is

out of the range.

8. Use the heat gun on the sanded cable insulation in order to get smoother surface. Heat will

melt protrusions and smooth the dents in the cable insulation. The hot air temperature should be

approximately 600C. The heat gun nozzle should be approximately 2 (50 mm) from the insulation

surface. Apply the heat in slow circular movements until the cable insulation starts to be shiny. It

takes 5 to 10 minutes to treat exposed cable insulation with heat.

9. After the insulation has cooled down, wrap the cable end with clean plastic wrap to protect

the cable from contaminants.

8. Check that the top surface of thebase plate collar is even with the top

surface of the PVC tape at mark

Z. If required adjust the cable. Figure 7.4: Distance Z

CAUTIONBe sure that Z dimension is as specified. This dimension not being correct can cause cablefailure.

9. Cover the space between the cable and base plate collar with cloths to stop the grease leaking

down the cable.10. Place the entrance housing O ring into the housing groove and attach the housing to the base

plate with provided M8 bolts. Torque to 15 Nm (10 ft-lb).11. Mark the cable even with the bottom surface

of the housing using marking tape. This

mark will be used to check if cable moved

during installation of the stress cone.12. Fold back the stress cone flap.13. Make sure there is no contamination on the

inside surface of the stress cone. Applyprovided AP paste liberally to the inside

surface of the stress cone. Make sure there

are no dry spots. Dry spots will makeinstallation of the stress cone more difficult.

Figure 7.5: Preparing the stress cone for the installation14. Temporarily apply PVC tape over connectorthreads to protect the inside of the stress

cone during installation on the cable.

15. Thoroughly clean cable insulation. Apply provided AP paste to exposed cable insulation. Makesure there are no dry spots on the cable insulation. DO NOT apply the grease over semi

conductive insulation screen.

Fingers

STRESS CONE SLIPPING

16. Slip the stress cone over the cable until it sits flat on the base plate collar.There are three possible ways of installing the stress cone. As a part of the

tools provided by G & W there is a plastic slider like one shown in Figure

7.6. It is used in first two options to slide the stress cone down the cable. The

Figure 7.6: Slider


15/21

GWI 36D-47

Page 14 of 20

slider is split vertically so it can be opened and positioned or removed from the cable at any point.

When using a slider, do the following steps:- Apply the AP paste to the both inside and

outside surfaces of the slider.

- Position the slider on the cable with slidersfingers facing towards the connector as shown in

Figure 7.7.- Slip the stress cone over the connector and onto

the sliders fingers approximately 1. Be sure thatthe top section of sliders fingers is inside the

stress cone bore.

First option is to wrap the stress conearound with clean cloths and then to pull

the stress cone down the cable. When thestress cone bottom is close to marked position Z (approximately 1 to 2), pull up the

stress cone just to release the slider and remove the slider from the cable by unfolding it.

Then push the stress cone further down to the marked position.

Figure 7.7: Using the slider

CAUTION

DO NOT push the stress cone below the marked position. Wrong position of the stresscone can cause cable failure.

Minimum (2) people are required for this job. The cable should be supported and secured to

the mounting structure to prevent its longitudinal movement during installation.

Second, easier alternative is to use optional installation ring with handles and manually slip

the stress cone to the required position on the cable as shown in Figure 7.8. When the stress

cone bottom is close to marked position Z (approximately 1 to 2), pull up the stress conejust to release the slider and remove the slider from the cable by unfolding it. Then push the

stress cone further down to the markedposition.

Installation ring

Removing

the slider

CAUTION

DO NOT push the stress cone below the

marked position. Wrong position of the

stress cone can cause cable failure.

The installation ring with handles has to be

purchased separately. Again, minimum (2)people are required for this job. The cable

should be supported and secured to themounting structure to prevent its longitudinal

movement during installation.

Figure 7.8: Installation of the stress cone using the

installation ring

Third alternative is to use optional stress cone installation fixture. It consists of a handwinch, wire rope with a hook, plastic tube and installation ring. This assembly is to be


16/21

GWI 36D-47

Page 15 of 20

attached to the connector with installation ring positioned on the stress cone as shown

below. Apply grease over conical surfaces of the stress cone and installation ring. Using thehand winch and pressing the installation ring slip the stress cone down to the required

position on the cable. See Figures 7.9 and 7.10.

CAUTION

DO NOT push the stress cone below the marked position. Wrong position of the stress

cone can cause cable failure.

From time to time back off winch and reposition installation ring. This will prevent the ring

from jamming onto the stress cone.

Advantage of this option is that the cable does not have to be supported in its final position.

17. Observe the marking tape over the entrance housing and verify that the cable didnt move

during stress cone installation.

CAUTION

If the cable moved more than 3 mm (1/8) pull the cable up and further slip the stress cone to

required position. Wrong position of the stress cone can cause cable failure.

18. Clean cuffed flap of the stress cone and baseplate collar with dry, clean, lint free cloth.

Unfold the stress cone flap and secure withprovided tie(s) to the base plate collar. Tie

heads should be approximately 90 apart.19. Wipe the cable insulation and the stress

cone with clean dry, lint free cloth and cover

with plastic wrap.

NOTE

The stress cone and termination can also be

installed with the cable in horizontal position.After installation is completed, the cable is

lifted and termination is placed on the mounting plate. During this operation it IS NOT allowed to

rotate the base plate relative to the cable more than 6mm (1/4). More markings and up-frontplanning is required in order that holes on the base plate are lined-up with holes in the mounting

plate once termination is lifted.

1. Clean the base plate O ring groove. Use new O ring

from plastic bag with O rings. Lubricate the base plate

O ring with AP paste andplace into the groove.

2. Remove the cap plate and theO ring from the insulator.

Discard the O ring.3. Remove plastic wrap from the

cable and stress cone and

lower the insulator to the baseplate.

4. Measure the distance betweenthe connector top and insulator

top as shown in Figure 9.2. For69 kV through 161 kV outdoor

terminations this distance

should be 186 5 mm (7-5/16" 3/16"). If the distance is not

correct, adjust the vertical position of the cable to meetthis dimension.

CAUTION

Since this is a critical operation, BE SURE when infinal position, stress cone is sitting flat on the base

plate collar top. Wrong position of the stress cone cancause cable failure.
