Medium and high voltage cables
Standard
This product is based on GB/T12706.2 "Rated voltage 1kV (Um=1.2kV) to 35kV (Um=40.5kV) extruded insulated power cables and accessories Part 2: Rated voltage 6 kV (Um=7.2kV) and 30kV ( Um=36kV) cable" and GB/T12706.3 "Rated voltage 1kV (Um=1.2kV) to 35kV (Um=40.5kV) extruded insulated power cable and accessories Part 3: Rated voltage 35kV (Um=40.5kV) Cable" production.
Features and uses
Cross-linked polyethylene insulated power cables use chemical or physical methods to transform polyethylene molecules from linear molecular structures to three-dimensional network structures; from thermoplastic polyethylene to thermosetting cross-linked polyethylene, which greatly improves Improved its heat resistance and mechanical properties, and maintained excellent electrical properties.
The conductor working temperature of the cross-linked polyethylene insulated power cable is 90°C, and it has the characteristics of simple structure, light weight and chemical resistance, easy to use, and not restricted by the installation drop.
The cable is used for power frequency voltage U0/U6/6 (6/10), 8.7/10 (8.7/15), 12/20, 26/35 (26/45) kV power transmission and distribution system.
