FAQS

Frequently Asked Questions (FAQ)

Cold shrink joints are made of pre-expanded silicone rubber that automatically contracts around the cable when the inner core is removed. This method eliminates the use of heat and open flames.

No. The cold shrink design eliminates the need for heat, flame, or special installation tools, making it safer and faster to install, especially in confined or sensitive areas. 

Yes. Cold shrink technology is ideal for sensitive or hazardous zones where flame-based methods are restricted.
Yes. Kits are supplied with either mechanical (shear bolt) or compression connectors, based on project specifications.

They are tested and certified according to IEC 60502-4, IS 13573, CENELEC HD 629.1 and are RoHS compliant.

 The CCSJ is designed for straight-through jointing of XLPE insulated medium-voltage power cables up to 42 kV, covering conductor sizes from 185 mm² to 1000 mm². 

Absolutely. Its quick installation, high reliability, and resistance to harsh environments make it ideal for solar, wind, and other renewable energy installations.
