Good Aerial Cable Accessories Manufacturers – 35kv Cold Shrinkable Type Cable Joint – Pengyou Power Detail:
6~35kv Cable Accessories Classification Introduction
4E-NLS Cold Shrinkable Indoor Termination, 4E-WLS Cold Shrinkable Outdoor Termination, 4E-JLS Cold Shrinkable Joint
4E-NLS cold shrinkable indoor termination, 4E-WLS cold shrinkable outdoor termination, 4E-JLS cold shrinkable middle joint are mainly composed of prefabricated body, terminations (indoor and outdoor) or connecting tube (middle joint) cold shrinkable multi-core fingerstall ( supporting multi-core cable), and cold shrinkable insulation 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 shrinkable structure: using latest expansion equipment and expansion support tube to ensure product expand without damage.
Easy installation: using cold shrinkable expansion structure, there’s no need special training, the labor is low due to convenient installation.
