It is an insulation and sealing component used for the intermediate connection of 20/24KV power cables.
Conductor connection part: Using crimping or welding technology to reliably connect the two cable conductors, ensuring good electrical conductivity between the conductors, reducing contact resistance, and minimizing energy loss.
The insulation layer is made of silicone rubber material, which has excellent insulation performance and corona resistance. It can withstand 20/24KV voltage and prevent current leakage and short circuit.
Stress control structure: Using special shapes and materials to improve the electric field distribution at the cutting point of the cable insulation shielding layer, reduce the electric field strength, avoid partial discharge, and ensure stable electrical performance of the joint.
Inner and outer semiconducting layers: The inner semiconducting layer is tightly adhered to the insulation layer, creating a uniform electric field; The outer semiconducting layer is connected to the outer semiconducting shielding layer of the cable to prevent electric field concentration and provide shielding.
Sealing structure: composed of rubber sealing rings, sealant, etc., to prevent moisture, dampness, and other pollutants from entering the interior of the joint, ensuring long-term stable operation.
