35KV Теплоусаживающ Совместное

Product Introduction: 35KV heat shrinkable joints are designed for 1 and 3-core XLPE power cables. The whole set contains heat shrinkable outer and inner insulation tubes,stress control tubes, sealing tubes,protective tubes,self adhesive tape and voil filler.Its unique patented water-proof design ensures the higher security of cable accessories. Its high permittivity material endows it unique stress control system. And with compact design and few components, this product is easy to install, minimal waste for disposal. Fast, consistent installation means lower installing costs. Installation environment: use of torch adds flexibility to cable preparation in any climate. It also has high reliability. Heat-activated seals ensure maximum protection against moisture ingress. Lightweight construction requires no additional support. UV resistant, non-tracking outer tube for long life, even under adverse conditions. It also has excellent mechanical robustness. Characteristics: 1.Operating Temperature:-40 degree - 110 degree; 2.Shrink Temperature:90 degree; 3.Waterproof, RoHS compliant.
