Product Features:
Liquid Silicone Rubber Injection Molding: Provides constant shrinkage pressure on the cable body, allowing it to "breathe" with the cable, resulting in low partial discharge.
Waterproof Insulation Tape: Restores the inner and outer sheaths with reliable sealing.
Special "Armor Tape": Offers external protection and ease of installation.
Versatile Applications: Suitable for intermediate connections in rubber and plastic insulated power cables, including harsh environments such as mines and underwater.
35 kV Single-core Joints: Please specify whether you need a through-type or insulated type when ordering.
