3.2 Outdoor/Indoor end termination Kit: LT/HT Cables

BefClre providing end termination kit to the cable, the cable end of the equivalent length of the

moulds, shall be prepared by removing the outer PVC insulation along with the steel armouring.

The ferrule shall then be inserted over the bare core of the cable, and shall be crimped with

hydraulic I mechanical type heavy duty crimping tool. The crimping shall be done in such a manner

that there shall be no air gap. Then the crimped portion shall be wrapped first with the PVC

insulation tape and then with the insulation tape used for wrapping HT conductor. The above

method shall be carried out for all the cores strictly following the colour code. The leads of the cable

now shall be placed into the mould by using the epoxy spacer, for having sufficient gap in-between

the leads. The earth continuity lead shall be clamped to the ends of the cable. After covering the

cable leads with the PVC moulds, the edges shall be clipped after applying the adhesive on the

inside face of the moulds. The pasting of moulds shall be rigid and as far as possible leak proof, so

that the. epoxy compound shall not spill out. Now the duly stirred epoxy compound shall be poured

and fill till the compound rises through the risers provided on the moulds. After completing the

above procedure, the joint shall be allowed to dry out for at least 8 to 10 hours (for epoxy compound

to get hardened) depending upon the size of cable. Before connecting to supply, the dry and
