High-voltage cable accessories are integrally prefabricated with imported high-elastic transparent liquid silicone rubber to facilitate product inspection. The reinforced stress cone structure is adopted to enhance the end sealing effect and reduce the deformation of the stress cone during expansion. The use of composite pre-expansion technology can realize rapid cold shrink installation of accessories, shorten product installation time, and improve product installation quality.
Cold shrink cable head
High-voltage cable accessories can realize insulation and straight-through connection of cable shielding layer according to user needs. The conductors in the cable joint are crimped according to the specified tonnage using hexagonal press molds. The contact resistance is small and has strong mechanical strength, which can fully meet the requirements of normal operation and short-circuit operation of the line.
Cold shrink cable joint
The straight-through intermediate joint of high-voltage cable accessories adopts an overall prefabricated structure. The outer diameter of the cable insulation is greater than 3mm on one side, and the interface pressure is greater than 2MPa, which can ensure that the insulation interface has sufficient pressing force. The cable insulation intermediate joint adopts a double-sealed structure of copper shell and fiberglass waterproof shell. The waterproof shell is filled with room-temperature curing waterproof casting agent, which has good waterproof properties. At the same time, the fiberglass waterproof shell has strong mechanical strength, can reach the same insulation level as the cable outer sheath, and can withstand the impact of certain mechanical external forces.
