WOER cold shrink tubes provide hassle-free, flame-free installation - perfect for on-site operations. Made of high-elasticity silicone rubber or EPDM, they form waterproof seals while delivering superior electrical insulation for medium/low voltage systems. UV-resistant and temperature-stable (-40°C to +105°C), they offer robust mechanical protection against tension, compression and impact. Widely used for cable joints, terminations, T-branches and repairs in diverse environments, these maintenance-free tubes ensure long-term reliability.
Cable joint protection: used for insulation and waterproof protection of intermediate joints and terminal joints of power cables.
Cable repair: used to repair damage to the outer sheath of the cable or damage to the insulation layer.
Branch protection: used for insulation and waterproof protection at the cable branch.
Communication cable protection: used for joint and terminal protection of communication cables.
Outdoor application: suitable for insulation and protection of outdoor cables, such as photovoltaic, wind power, etc.
The production of cold shrink tubes is a precise process involving material selection, pre-expansion, support core installation and quality control.
Material selection: Silicone Rubber or EPDM.
Tube extrusion and vulcanization.
Use a special expander to radially expand the vulcanized tube to make its inner diameter reach the designed size, and then cool it to shape.
Support core installation.
Cutting and packaging.
Quality control: size detection, performance testing; test insulation resistance and withstand voltage performance, mechanical properties and weather resistance.
