Product Description

Rubber Cold Shrink Tube
Cold Shrink Terminations & Joints 1-36kV
Description

Cold shrink cable accessories are manufactured with advanced liquid silicon rubber, which has high resilience and strength,good electrical insulation, is

UV stable and adverse to water. The cold shrink cable terminations & joints applications from 1 to 36kV(1kV, 12kV, 15kV, 20kV, 36kV). The simple installation of 

cold shrink cables accessories can help you save time and physical force. It improves your work efficiency, make the cables connect safely and reliably, assure your every connection correctly sealed and insulated for long protection. So our cold shrink MV terminations & joints are widely applied in power plant (nuclear), wind farm, substations, city subway etc.

Cold Shrink Cable Joints 

Use:

Cold shrink cable joint for XLPE -insulated 1 or 3 cores cables with Al or Cu conductor, 1-36kV.

Design:

The joint body is made of advanced liquid silicone rubber with three layers: a conductive outer layer, an insulating layer and a conductive inner layer.

The joints kit contains all mounting material. It improves reliability, reduces time and labor. It fits cable sizes from 25mm2 to 500mm2.
