Outdoor/Indoor end termination Kit: LT/HT Cables:
- Before providing an 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 armoring.
- The ferrule shall then be inserted over the bare core of the cable, and shall be crimped with a hydraulic / 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 intended end 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 filled till the compound rises through the risers provided on the moulds. (Refer drawing no. CB-JT-2).
- 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.
