Have another one for the forum.
Same client wants to move existing 40+ year old 3/C, 350 MCM power cables and re-route them to some new transfer switches.
I have serious concerns whether the cables will survive the physical bending, re-routing, moving around, etc. I fear the aged insulation will crack, etc. and fail upon re-energization.
Anyone on the forum have any hard experience here?
My experience has been such drastic movement cracks the insulation and we ran new cables to avoid the problems.
We are dealing with at least 18 cables with multiple moves. Critical process area that affects the whole plant and only a 6 day shutdown window. We're also looking at several hundred 480V terminations, splices, etc. all in the same electrical building!
Thanks!
