Product Description
Product Description
Full cold shrink technology : No open flame or special tools are required, and there is no trouble of gradually inserting it. Just gently pull out the core rope, and it will shrink back due to its own elasticity, thus attaching tightly to the cable and completing the installation.
Integrated design : The climbing skirt, the enhanced insulation of the terminal head, the terminal port seal and stress control components are prefabricated as a whole in the factory. The single-core terminal diameter reduction design allows for one-time shrinkage after cable processing, which is convenient for installation and minimizes the impact of various adverse factors in on-site installation .
Reliable insulation : Made with imported liquid silicone rubber, ensuring excellent insulation and a high yield rate. It effectively eliminates impurities and air bubbles in the product, and provides constant and lasting radial pressure to the cable body after installation. It has low partial discharge and "breathes" with the cable body.
Easy installation : Installation is simple, with low technical dependence on operation. Cable pretreatment requires a short stripping distance and minimal installation space. Grounding uses a constant force spring process, eliminating the need for welding or copper binding wire, making it faster and more reliable.
Widely applicable : It is stain-resistant, aging-resistant, hydrophobic, corrosion-resistant, and UV-resistant, ensuring stable performance over long-term use. It also possesses excellent cold-resistance, making it particularly suitable for high-altitude, cold, humid, salt-spray, and heavily polluted areas.
