Pre-molded cable termination product introduction:
Pre-molded indoor and outdoor terminations are inlaid with stress control parts in the insulation body in advance in the factory production, no interface exists, through the stress control parts to effectively solve the problem of stress concentration at the cable shield cut. Using silicon rubber high resilience, high temperature resistance and strong aging resistance, and cable insulation to adopt interference combined design. This ensures that the interface between cable insulation and accessories is closely combined without internal creepage. In order to meet the four types of pollution environment, and design the external insulation of the accessories. 15kV prefabricated cold shrinkage power cable accessories are suitable for the connection of 6/10kV, 8. 7/15kV single/three core XLPE power cable.
Product execution standards: IEC60502.4, GB/T12706.4
