35kv Cold Shrinkable Indoor Cable Termination

6~35kv Cable Accessories Classification Introduction4E-NLS Cold Shrinkable Indoor Termination, 4E-WLS Cold Shrinkable Outdoor Termination, 4E-JLS Cold Shrinkable Joint4E-NLS cold shrinkableindoor termination, 4E-WLS cold shrinkableoutdoor termination, 4E-JLS cold shrinkablemiddle joint are mainly composed of prefabricated body, terminations (indoor and outdoor) or connecting tube (middle joint) cold shrinkablemulti-core fingerstall ( supporting multi-core cable), and cold shrinkableinsulation tubes and relative colormetric tube (indoor and outdoor termination). The prefabricated body stress cone and insulating body are using plastic injection molding of liquid silicone rubber, which has long-term stability of the package tight force and uniform electric field capacity. Always keep a suitable radial pressure to the cable body. The interface characteristic is good without respiration creepage breakdown when cable runs. The terminations or connecting tube meet cable core material requirements or users' requirements to ensure the protection of cable insulation and waterproof. Main structure features:Excellent raw-material: prefabricated body is composed of high quality liquid silicone, which has excellent insulation, elongation, and breakdown properties, small residual deformation after expansion.Cold shrinkablestructure: using latest expansion equipment and expansion support tube to ensure product expand without damage. Easy installation: using cold shrinkableexpansion structure, there's no need special training, the labor is low due to convenient installation. 6~35kV Cold Shrinkable Outdoor TerminationLug2.
