  • Power Cable

    Power Cable

    Power cables are mainly used for power transmission and distribution purpose. It is an assembly of one or more individually insulated electrical conductors, usually held together with an overall sheath. The assembly is used for transmission and distribution of electrical power. Electrical power cables may be installed as permanent wiring within buildings, buried in the ground and run overhead or exposed.……Including: rubber cable, welding cable, URD cable, XLPE insulated power calbe etc.

  • Bare Overhead Conductor

    Bare Overhead Conductor

    Bare Overhead Conductors are used in overhead transmission and distribution network applications.They are also used for un-insulated hook ups, jumpers, grounding conductors and other applications. Our Conductors conform to ASTM, IEC, BS, BS EN and DIN standards.…… Including: AAC conductor, AAAC conductor, ACSR conductor, ACAR conductor, AACSR conductor, etc.

  • Aerial Bundled Cable

    Aerial Bundled Cable

    Aerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. Our abc calbe conform to ASTM, IEC, SANS standards.……Including: abc cables, cvered line wire, service drop wire etc.

    • Armoured cable
    The Armoured cable is used in various fields of AC rated voltage 35kV and below  fixed line, used for power transmission and distribution, and can replace paper insulated power cable. Ordinary type products comply with GB/T12706 requirements, and consistent with the IEC60502 standard. Fire retardant products in addition to meet the above criteria, also need to comply with the GB/T18380.3 standard, and consistent with the provisions of IEC60332-3.
     
    In which fire retardant armoured cable is especially suitable for power station, nuclear power plant, petrochemical, urban rail transportation, high-rise buildings and other special requirements fixed laying occasions.
     
    The product is suitable for U0/U*kV 3.6/6, 6/6 (6/10), 8.7/10 (8.7/15),12/20,  18/20 (18/30), 21/35, 26/35 transmission and distribution system.
    *U0: rated power frequency voltage between conductor and shield in cable
    U: rated power frequency voltage between conductors in the armoured cable
     
    The use of characteristics:
    1, the cable conductor is allowed to work for a long time at 90℃.
    2, the maximum temperature of the cable conductor is no more than 250℃, the longest short-circuit time is 5 seconds.
    3, the cable body and the environment temperature is not less than 0℃ when laying armored cable.
    4, the cable allows the minimum bending radius: single core cable is 20 times of the cable diameter, the multicore cable is 15 times of the cable diameter.
    5, cable laying is not limited by the difference of level.
