he Best Solution to Fire-resistant Wires and Cables of LV & MV


Cold shrink cable accessories are capable of shrinking without application of heat. They are manufactured in a pre-expanded condition and assembled onto a removable core. The core is removed after the tube is positioned over the cable for installation, allowing the tube to shrink and providing a moisture-tight seal.
Woer cold shrink cable accessories are characterized by simple solutions with safe connection. They are manufactured with liquid silicone rubber, which has high-quality electrical insulation, excellent tracking resistance as well as high elasticity.


Heat shrink cable accessories are made of rubber/plastic composites. After exposure to radiation, the semi-finished product is heated and stretched to expand its dimension. It is then rapidly cooled in order to keep its shape. When installing, the cable accessories will shrink back down to the original dimensions by applying heating because of their “shape memory effect”. Therefore, the heat shrink cable accessories will provide excellent insulation, sealing and mechanical protection for power cables.
