36KV up to 500KV Cu/Al XLPE insulated Power Cable
1. product' s introduce in details:
A high-voltage cable (HV cable) is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation, and is suitable for being run underground or underwater. This is in contrast to a conductor, which does not have insulation. High-voltage cables of differing types have a variety of applications in instruments, ignition systems, and AC and DC power transmission. In all applications, the insulation of the cable must not deteriorate due to the high-voltage stress, ozone produced by electric discharges in air, or tracking. The cable system must prevent contact of the high-voltage conductor with other objects or persons, and must contain and control leakage current. Cable joints and terminals must be designed to control the high-voltage stress to prevent breakdown of the insulation. Often a high-voltage cable will have a metallic shield layer over the insulation, connected to the ground and designed to equalize the dielectric stress on the insulation layer.
2 . Application:
The XLPE insulated power cable is used in electric transmission and distribution system operating in vertical section, indoor, tunnels, mines. It was widely used in crowded public places such as high-rise building, large-rise library, gymnasium, station, subway, underground shop, etc. The XLPE insulated power cable not only has excellent electrical performance, mechanical performance. heat-resistant & anti-aging performance, environment resistant character & chemical-corrosion resistant performance ,single structure, light weight, without restriction by laying fall, but it also has high temperature(90℃) for long time.
3 . Standard:
We produce these cables according to standard GB12706( equivalent to IEC60331), as well as BS, DIN and other international standards. In additional, we can also produce the low-smoke free halogen, Flame-retardant cables, or others according to customer request.
