Removal of armour
(OP)
We have a situation where it is not feasable to use bus (space issue).
Usually, in this application we would use 4 runs of 5kv unshielded 500mcm cable per phase. Our supplier has told use that this cable is no longer available, unless special order, i.e. no orders under 1000ft, and a hefty price to match!
Is there any problems with using 5kv teck and stripping the armour? There is no chance of mechanical damage to the cable (it is in a enclosure from xfmr sec to main breaker).
My only concern is that I will have to get the installation passed by CSA with cable that has no markings on it what so ever. Are there any other concerns?
Regards,
Tulum
