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 breakout

HSLB, heat shrink breakout for 1kV, is made from radiation cross-linked polyolefin, which environmental and mechanical protection for 2-core, 3- core, 4-core and 5-core armored or sheathed cables. The breakouts are UV resistant and consist of adhesive inside to create air tight seals. The heat shrinkable breakouts material and design make it perfect to seal electrical connections that need superior insulation and water proof protection.

The HSLB has excellent properties of electrically insulating, UV resistant and water proof, it is widely used in electric power industry to provide insulation and sealing over the crutch of multi-core cables.
