Heat shrink cable accessories 10-36KV

Cotran heat shrink terminations (indoor/outdoor) are precisely designed to meet the parameters of international cable and cable accessories standards such as CENELEC HD 629.1 S1, IEEE-48, IEEE-404, IEC60502. Our heat shrink terminations offers reliable and consistent performance for longer service life. We have designed our heat shrink terminations for single core and 3 cores extruded UA, SWA/STA, CWS/CTW cable through 36KV.

Heat shrink cable accessories 1KV

Cotran heat shrink terminations and joints are composed of a series of pre-expanded adhesive lined heat shrink tubes and necessary accessories. Heat shrink and provide excellent waterproof seal and electrical insulation. The terminations and joints are designed to be suitable for SWA/UA, XLPE/PVC/PILC, S/C, multi-core cable rated to 0.6/1kV.

Wraparound Repair Sleeve

Cotran wraparound repair sleeve (CWRS) is designed to repair damaged cable jackets and protect cable or pipes where needs corrosion protection on undamaged ones. CWRS is made from modified cross-linked polyolefin (XLPE) with a hot-melt adhesive. When heating, the sleeve shrinks and the adhesive melts, thereby achieving tightly bonding between the sleeve and the cable. It provides an excellent solution of protection against mechanical stress, harshest environments, moisture and corrosion.

CWRF is a fiber reinforced repair sleeve, which is composed of XLPE and fiber layer. It can provide better mechanical properties. CWRA is a fiber reinforced and aluminum layer reinforced repair sleeve, which is composed of XLPE, fiber layer, and aluminum layer. It can provide more stronger mechanical properties than CWRS and CWRF.

Heat Shrink Rain Shed (10~36kV)

Applications：

Used to provide insulation protection for cable outdoor termination in order to increase the creepage distance and avoid the formation of sewage for various of rod supporting insulators.
