Damage to Single Core Cables

Thankyou IQ for your detailed comments.

Just to let you know cable is non shielded, has no semi con, has a concentric wire shield of 2/0, wire shield was only connected to ground on the pole side, not at switchgear. They were connected together but isolated from ground at this end.

Cable Structure - PVC Jacket - Aluminum Interlocking Armour - Inner PVC Jacket - Concentric Copper Ground Wires - XLP Insulation - conductor shield ( not semi conductive) - and 750 MCM Copper Conductor.

What would be approx. sum of currents flowing in this case?

We do have some slack in cables and could do new terminations. Also this being a non shielded cable we can remove concentric ground wires back closer to top of gland entry point, bend wires back /cut & tape for isolation . Cable can be terminated without stress cones?

Please Comment. Again thanks for all comments. Electron.
