1kV low voltage cold shrink cable joint is specially used for low voltage (1kV and below) cable system, Suitable for the connection of single-core, double-core, three-core, four-core and five-core cables. It uses cold shrink technology to tightly wrap the cable connection, providing reliable electrical insulation, mechanical protection and environmental sealing.

Applicable to low-voltage cable systems of 1kV and below.
Supports single-core, 2-core, 3-core, 4-core and 5-core cables.
No need to heat, relying on elastic materials to shrink automatically, easy to install.
Usually silicone rubber or ethylene propylene rubber (EPDM) is used, with good insulation performance, weather resistance and mechanical strength.
Waterproof, moisture-proof and dust-proof, suitable for indoor and outdoor environments.
