  • 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.

    • 3 core power cable
    Application:
     
    Three core cable design and distribution range is 3.8/6.6KV to 19/33KV, the frequency is 50Hz. Mainly used in the power supply station, indoor and outdoor pipelines, underground water and other places, as well as the industry, power station, power station cable installation.
     
    Standard:
     
    IEC 60502 Part 1 (1.8/3KV)
    IEC 60502 Part 2 (to 18/30KV 3.6/6KV)
     
    Structure:
     
    Conductor: plain annealed copper or aluminum conductor, with IEC 60228 (1 class and 2 class).
     
    Conductor shield: conductor shielding should be non metallic, and should include a semi conductive compound, semiconductor band used in the top of the semiconductor complex.
    The conductor shielding layer is applied to the three important extrusion process in the outer and the insulation shield. The conductor shielding layer is made of non metallic layer, and the semi conductive compound must be firmly adhered to the insulation, and all gaps are eliminated. Conductor shielding layer for 1.8/3KV – 3.6/6KV PVC, EPR/HEPR insulated cable is not necessary.
     
    Insulation: 1.8/3KV and 3.6/6KV cable is generally used in PVC insulation, can also use EPR/HEPR, XLPE insulation.
     
    Physical properties:
     
    Operating temperature: 70°C (PVC insulation), up to 90°C (XLPE or EPR insulation)
    Temperature range: -5 °C(PVC); -20 °C(PE).
    Short circuit temperature (the longest duration at short circuit is no more than 5S): 140-160 °C(PVC sheath);
     250 degree°C(PE sheath)
    Bending radius: 15D
