Product name:
Dielectric Constant Cable Cold Shrink Insulator For Telecommunication Industry
Product description:
Cold shrink tubing is an open ended rubber sleeve, made primarily from rubber elastomers with high-performance physical properties, that has been factory expanded or pre-stretched, and assembled onto a supporting removable plastic core. Cold shrink tubing shrinks upon removal of the supporting core during the installation process and the electrician slides the tube over the cable to be jointed, terminated or abandoned and unwinds the core, causing the tube to collapse down, or contract, in place.
