Grounding MV Cable.
Grounding MV Cable.
(OP)
I don't do MV cable much and I'm a little confused on an grounding issue. I have 13.2kv coming form a overhead line going underground to Switchgear. I'm pulling single conductors MV Cable in the conduit. Should I ground the shields just at the Overhead pole or at both the pole and the switchgear? Is a grounding conductor also required for this application?






RE: Grounding MV Cable.
It is safer to ground the shield at each end. This can create current in the shield which may require that the cable ampacity be de-rated a bit.
Contact your local Okonite Cable office, or try their website. Their cable installation manual has some good information on shield grounding. Southwire can probably provide the same information.
