High voltage

 

Up

   

High voltage crosslinked polyolefin bus bar tubing, up to 36 KV. Reduces bus bar clearance requirements, protects against accidental flashover, anti-track, halogen free.

Continuous operating temperature between -40oC and 125oC, with a shrink temperature of 120oC

Shrink ratio more than  2:1 and dielectric strength of  20 KV/mm.

Red standarized color for this voltage level.
