Parallel unshielded 5kV feeder cable
Parallel unshielded 5kV feeder cable
(OP)
I need to parallel an existing 600ft run of 3 conductor w/gnd 5kV MV-90 500kcmil IAC type cable for an expansion. NEC states 5kV cable needs to be shielded and parallel cables need to be of the same basic design and terminated the same way. Seems shielded cable would have different characteristics. Can shielded cable parallel unshielded? Is there a caveat that would allow me to use unshielded? Could the local AHJ grant a variance in this instance?

You can distribute the existing "C" phase conductors between "A" phase and "B" phase and add a new "C" phase of a different type of cable. Physically changing the existing cables into an acceptable configuration will be a challenge.
