Are skirts of termination kits on the same phase allowed to touch?
Are skirts of termination kits on the same phase allowed to touch?
(OP)
Say we have cables (two per phase) terminating at a bus, can the skirts of the cable termination kits ON THE SAME PHASE touch?
Would the voltage potential throughout the length of the termination on both cables be equal? Or would there be slight differences of potential between the two terminations that it would cause problems? Any other concerns? If they are not allowed to touch at all, is there a minimum amount of separation recommended? The cables are 15kV.
Thanks.

Raychem {er, Tyco} used to have an application note/drawing for their HVS-series terminations at their site but I can't seem to find it now.

For the indoor type without skirts, it may not be as important.

We avoid this by installing a piece of 4in copper bus drilled to NEMA hole pattern. In an overhead application we also include a bail off one side to hang an arrestor, thereby eliminating any voltage difference between the arrestor and termination.
