10kV 15kV Cold Shrinkable Products
Product Introduction:
CN-NLS cold shrinkable indoor termination, CN-WLS cold shrinkable outdoor termination, CN-JLS cold shrinkable straight through joint are mainly composed of prefabricate main body, terminal lug, cold shrinkable breakout, cold shrinkable insulating tube, phase color tube. The stress cone inside prefabricate main body and the insulating body adopt imported liquid silicone rubber injecting formed which has long-term stability of lasting hold power and electric field uniform ability. Keep a suitable radial pressure to the cable with good property of interface, there is no creepage raise from respiration when cable runs. Cable lugs and other supporting materials are based on customers’ requirement, ensure cable insulating and waterproof.
Product Characteristics:
Excellent raw-material: prefabricate main body is adopts high quality liquid silicone rubber, which has excellent insulation, elongation, and breakdown properties, small residual deformation after expansion.
Cold shrink structure: using latest expansion equipment and expansion support tube to ensure product expand without break.
Easy installation: using cold shrinkable expansion structure, there’s no need special training, convenient installation.

CN - NRS CN - WRS CN – JRS heat shrink series cable accessories
CN - NRS CN - WRS CN – JRS heat shrink series cable accessories is applied to 35kv and below rubber cable. Heat shrink cable accessories is using import multiphase polymer, it’s the update products of wrapped type cable accessories. With convenient installation, keep on suitable radial pressure on the cable body, interface characteristic is good. the parameter type stress control tube to improve the distribution of the electric field, which can effectively solve the cable outer shield section in electric stress concentration problem. The electrical properties are improved from wrapped type cable accessories to ensure the safty and reliable operation. The main components are tubular, basically includinig stress tube, insulation tube, three fingeed tube, sealed tube protective sleeve, etc
Main performance and structure features:
Technical performance: meet BS EN 50181, IEC60502, GB/T12706 requirements.
Heat shrink raw materials: stress tube is parameter type, well-distributed electric field at the insulating cable cut off place. Insulatingtube has insilation effect, protective sleeve has protection effect. Product heat shrink is quite stable, can shrink to the orginal size in heating condition, the residual deformation is small. All the products are processing forming in the factory. There’s no need to use fire, no special training, installation is simple and fast.
It has resistance to filth, aging, and good waterproof, with superior cold heat resistant performance.
Surface is smooth and beautiful.
