What is power cable?

Power cable is used for the transmission and distribution of electric power cables, power cables are often used in urban underground power grids, power station lines, industrial and mining enterprises internal power supply and underwater transmission lines across the river and sea.

Second, what is power cable?

The diameter of the line is thick, generally 3 core or four core, and the insulation is thick, and the outside is protected by metal armor. It is used for power supply system as the main trunk of three-phase industrial power or single-phase civil power.

Third, the difference between power cables and power cables

Power cables are collectively referred to, power is only one of the sub-items, generally four or five lines, lighting is generally three lines.

Power cables are generally used on machinery and equipment, and power cables are used for lighting.

Type of power cable

Representative model: VV/VLV/YJV, etc. 35kv and below crosslinked polyethylene insulated power cable

Main application

35kv and below crosslinked polyethylene insulated power cable is suitable for fixed laying in AC 50Hz, rated voltage 35Kv and below power transmission and distribution lines for the transmission of electric energy. Compared with polyvinyl chloride power cable, the product not only has excellent electrical properties, mechanical properties, heat aging properties, environmental stress resistance and chemical corrosion resistance, but also has the characteristics of simple structure, light weight, not limited by laying drop, long-term high working temperature (90 degrees).



Executive standard

GB/T12706.1~12706.4-2002 "Rated voltage 1KV (Um=1.2kV) 35k (Um=40.5kV) extruded insulated power cable and accessories", can also be according to user needs, using the Electrotechnical Commission IEC60502-1997 standard production.

Service characteristics

1. The ambient temperature when the cable is laid shall not be lower than 0 ° C, otherwise it must be pre-heated. The laying drop of the cable is not li
