MV Cable Shield Type
MV Cable Shield Type
(OP)
I have typically seen Medium Voltage cable with a copper tape shield between the conductor and the insulation in order to provide a uniform grounded shield on the cable. In speaking with a facility recently they mentioned that because of the plant environment they have had issues in the past the copper shield corroding and have thus specified a MV cable with a bare copper concentric conductor with the intent of using the concentric conductor as the cable shield and terminating shield to stress cones as you would with the tape shield.
I was curious if there was any advantage or possible disadvantage to using this concentric conductor shied as opposed to using the tape shield that I have typically seen on most cables? The concentric shield does not seem like it would provide as much as a uniform distribution that the tape shield would.
