Series | YJLW |
66 - 500kV High-Voltage Power Cables with Cross-Linked Polyethylene (XLPE) Insulation are crucial components in modern power transmission systems. Designed to operate within a voltage range from 66 kilovolts to 500 kilovolts, these cables are primarily used for long - distance and large - capacity power transmission, connecting major power generation sources like power plants to substations in urban centers, industrial areas, and other key electricity - consuming regions. The cross - linked polyethylene insulation provides excellent electrical and thermal properties, ensuring stable and reliable power delivery over extended periods.
