Cold shrink cable accessories utilize the high elasticity of silicone rubber material to inject and mold high-temperature vulcanized silicone rubber into various tubular components of different structures. Special machinery is then used to expand the tubular components of different structures. When the inner diameter of the component expands to about three times, a specially designed plastic support tube is placed into the tubular component to keep the silicone rubber tubular component in an expanded state. These expanded components become the components of cold shrink cable accessories.

During on-site installation, these expanded components are inserted into the treated cable ends or joints, and the internal support tubes (strips) are pulled out. The silicone rubber components automatically shrink and press onto the cable insulation. It is designed as a cable accessory. Because it relies on the elastic shrinkage force of silicone rubber at room temperature, rather than heating and shrinking with fire like heat shrink cable accessories, it is commonly known as cold shrink cable accessories.
