An 8.7/15kV XLPE insulated power cable for AC 50Hz distribution networks, industrial installations and fixed power transmission.
Designed for electrical distribution systems that require stable operation, clear circuit protection, and practical installation for industrial, commercial, utility, and infrastructure projects.
Dongfang Electric Power (Shandong) Co., Ltd. supports product selection by voltage level, rated current, installation environment, cabinet structure, cable connection method, and project documentation needs.
High Voltage Power Cable
8.7/15kV XLPE Insulated Power Cable
XLPE insulated power cable uses chemical or physical methods to transform the linear molecular structure of polyethylene insulation into a three-dimensional network molecular structure. This changes thermoplastic polyethylene into thermosetting cross-linked polyethylene, greatly improving its heat resistance and mechanical properties, reducing shrinkage, preventing melting after heating, and maintaining excellent electrical performance.
