- Page 3 Lift the cable into the correct position. Mark (I) the oversheath at the upper edge of the support. Also make a lengthwise mark (II) on the oversheath approximately 200 mm below mark (I), for the orientation of the insulator. The work is carried out more easily on the ground with the cable lying horizontally.
- Page 4 Mark a distance of D mm from the end of the cable and remove the oversheath from this point to the end of the cable. If a cable with lead or corrugated sheath is used, use earthing kit JSA 1 Pb, Al. See instruction 4290.2617 and 4290.7961.
- Page 5 Starting 30 mm from the sheath edge, wrap one turn of FT around cable. Then proceed wrapping the FT with a half overlap so that it seals the sheath edge and covers 20 mm of the screen wires. Finish with one extra layer over the screen wires.
- Page 6 NB! It is important that the instructions in sections 6- 11 are followed correctly in order to obtain an even surface where any rubber parts of the accessory is to be positioned. Always use new and clean abrasive cloth on the insulation!! Make a mark (1) on the insula- tion screen M mm from the end of the conductor.
- Page 7 10-15 10. Preparation of the insulation screen and transition to insulation. Cover the insulation by using plastic film (1) up to 20 mm from the insulation screen edge. Preparation by hand only: Do not use any rougher abrasive cloth than 220 grit. Always finish by using 400 grit Max 10 mm abrasive cloth.
- Page 8 12. Place the cold shrink tube on the cable with the collapsing end in the cable end direction. Fasten the ends of the four braided copper bands on the outside of the insulator. Clean the entire inside surface of the stress relief cone. Grease (1) the stress relief cone inside the insulator.
- Page 9 15. Pull the insulator down with the chain blocks to about 100 mm from the edge of the insulation screen. Remove the sliding fingers and then pull the insulator down until the XLPE on top is flush with the top of the insulator. Wipe off excessive grease. Remove the sliding cone and ET on top.
- Page 10 17. Tighten the insulator top cover (1) or bolts in an alternating sequence to a torque of 45 Nm. If the conductor clamp (2) has nine bolts, the conductor (3) of the cable should end 10 ± 10 mm above the clamp. Should the clamp have fifteen bolts, the cable conductor end should be 0 ±...
- Page 11 19. Fasten the four braided copper bands (1) on the cable. Push the cold shrink tube (2) on to the stress cone. Remove the interior of the cold shrink tube by pulling and rotate. 1690a 20. Wrap IV on the cable ones between 200 and 300 mm from the insulator. Wind bitu- minized paper (1) hard over the IV to a diameter of approximately 150 mm.
- Page 12 21. For cables with a conducting layer on the oversheath. Remove the outer conducting layer for a distance of 200 mm from the end of the termination. Be careful to remove all conducting material. Do not remove more of the oversheath than necessary. Apply lashings (1) of copper wire around the cable with a distance of 50 mm and check the resistance with an insulation...
- Page 13 22. When the termination is to be lifted into its final position, the lifting sling (1) is to be secured around the top of the insulator. Lift the temination to its final position, check that the insulator gets a level contact with the bracket, if not, adjust with washers.
