REPL RIHTU Heavy Wall Heat Shrink Tubing (Uncoated) are unlined heatshrinkable tubes used for environmental sealing of plastic and paper insulated cable joints rated up to 36kV.
RIHTU Part Numbers: 12/4, 16/5, 20/6, 30/8, 40/12, 55/16, 80/20, 100/30, 120/ 34, 140/37, 160/50, 180/60.
These tubes are made from thermally stabilised, cross linked, UV and weather resistant polymeric material and have a nominal shrink ratio of 3:1 and an unlimited. The tubes can be supplied in a coated form – hot melt adhesive lined (RIHTA) depending on the application.
