Busbar Insulating Tubes 36kv

REPL heat shrinkable busbar insulating tubes (RIBT-T) are used to insulate copper and aluminium busbar up to 36kV preventing flashovers and accidentally induced discharge.
The tubes are made from thermally stabilized, cross linked, non tracking and weather resistant polymeric material and have a nominal shrink ratio of 3:1 and an unlimited shelf life when stored at normal warehouse temperatures.
