Removal of armour

[tulum]

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

Suggestion: Any modification of the cable will cause to lose its UL or other cable industry standard label.
This may pose a problem when it comes to approvals.
