▲11 kV UNDERGROUND CABLE JOINT – STEP BY STEP
11 KV XLPE UG cable using a jointing kit. From safety checks to final testing, every step matters to ensure reliability and safety.
Here’s the process step by step:
1 Safety & Isolation – Power isolated, discharged, and earthed ✔
2 Cable Prepared – Faulty section cut and ends prepared
3 Sheath & Armour Removal – Outer sheath and armour stripped
4 Insulation Cut-back – Screen & XLPE cut to kit dimensions
5 Phase Identification – Used a megger; earthed one end tested the other. Low resistance = correct phase, OL (Over Limit) = not selected
6 Copper Ferrule Crimp – Conductors joined with hydraulic crimping tool
7 Stress Control – Applied stress control tubing/tape to prevent breakdown >
8 Insulation & Sealing – Heat shrink insulation and sealing tubes applied
Armour Continuity – Earth bonding of armour reconnected
10 Final Sealing & Testing – Outer sheath sealed, IR tested, and ready to energize
