Applications

Cross-linked power cables are power transmission equipment suitable for power distribution lines with a rated power frequency voltage ranging from 3.6/kV to 26/35kV. The main models include CU/XLPE/PVC, AL/XLPE/PVC, and other series, and are produced in accordance with standards such as GB12706. The long-term operating temperature of its conductor does not exceed 90℃, and the radiation environment temperature needs to be above 0℃.

This cable adopts a Uo/U (Um) voltage classification system, where Uo is the rated voltage of the conductor to ground and U is the rated voltage between conductors. The bending radius of single-core cables shall not be less than 20 times the outer diameter, and that of three-core cables shall not be less than 15 times the outer diameter, suitable for different laying requirements. It adopts cross-linked polyethylene insulation and polyethylene/polyvinyl chloride sheath. Some models enhance mechanical and protective properties through armor structure. The factory test detects partial discharge and withstand voltage performance through a series resonant system, and it can be applied in cable trenches, tunnels, underground and special environments subject to mechanical external forces.

Other jacket materials/colors can be provided upon request, such as CSP/PCP/NBR/PVC.

Double-layer jackets with reinforced fibers in the middle are available as an optional configuration.
