Product Details
Adopt cold shrinkage technology, installation without fire, without heating, safe and reliable, save time and effort, and no gradual set into the trouble, only need to gently extract the core rope; grounding using constant force spring, without welding or copper binding line, construction time and effort to save space, for the construction of small space is especially suitable for the place. A model for a variety of cable diameters; complete supporting, without special tools, construction and installation of convenient and rapid; the use of high-quality liquid silicone rubber, its insulation is excellent, high resistance to tearing, fixed stretch rebound good, full cold shrinkage of the automatic reset technology, and the cable with the respiratory effect, sealing and insulation are good. Suitable for 12/20kV, 18/20 (30) kV cross-linked polyethylene, rubber insulated single-core, three-core power cable power connection.
