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.

Low voltage bus bar tube



HSBB 001, a heat shrink insulation tube for bus bar at low voltage, is a thin wall heat shrink tube which provides insulation enhancement and protection against flash-over and accidentally induced discharge Particularly useful in confined spaces in low voltage environments and greatly reduces the noxious and corrosive effects in fire situations. It can be used on both circular and rectangular copper or aluminium bus bars.

Color: black, blue, red, yellow.
