What's the "fix" for a situation where there are cables in a vault that operate in different voltage ranges--like for transformer line/load conductors, one set over 600V and the load side under 600V. In this scenario, the cables are coming into the vault in such a way that there is no way to place a rigid physical barrier between the conductors. Is it practicable to wrap the 600V conductors with high voltage insulation?

There is Raychem BBIT but it will cost you plenty. I'd be sure your inspector will buy in to it first.

I don't know what the Raychem product is that you mentioned. This transformer vault situation is something that someone else had run into recently, I haven't seen the installation myself. My understanding is that you can have shielded URD racked within 6" of the 600V wire, but if it is un-shielded you can't have it in the same enclosure.
