LV 0.6 1kV Cold Shrink Straight Through Cable Joints

Low Voltage 0.6 1kV cold shrink straight through cable Joints is a pre-assembled kit designed to create a permanent, insulated, and sealed connection between two low-voltage power cables. It is a most common and reliable method for splicing cables in modern electrical installations.

 

● Low Voltage (1kV): Designed for electrical systems with a rated voltage up to 1000 Volts. This covers the vast majority of industrial, commercial, and utility power distribution cables (400V,600V,1000V)

● Straight Joint: Also known as an "in-line splice," it connects two cables end-to-end

● Cold Shrink: installation does not require heat or flames.The joint core is pre-expanded and held on a removable plastic support spine. Pulling the spine releases it, then the rubber shrink tightly onto the cable

● Excellent Sealing and Moisture Resistance:Cold shrink joints use silicone rubber, which have a permanent elastic memory function. Even after many years, they remain tightly wrapped around the cable and will not loosen
