CABLE JOINTING AND SEALING

Our advantages

Beyond expectations 

we are aimed at bring reliable cable jointing and sealing SOLUTIONS.

We are inspired to do great work because we truly believe in what we do and we put our heart and soul into it.

High insulation tube

HST004 heat shrinkable high insulating tubes, are made from thermally stabilized cross linked polyolefin. The tube is designed for main insulation for cable joints for 24kV and 36kV.
