  • 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.

    • Shielded cable
    Shielded cable is the transmission line which is wrapped single wire by metal mesh braided layer. Braid layer is usually copper or tinned copper.
     
    Use characteristics:
    1. rated voltage 3.6/6KV U0/U
    2. the long-term working temperature of the cable conductor is 90°C
    3. the minimum bending radius of the cable is 6 times the diameter of the cable.
    4. cable shall not be exposed in the sun for a long time
    5. the bottom line core of the cable must be well grounded.
     
    Main technical performance:
     
    1. finished cable should withstand power frequency AC voltage test power line core is 11.0kv 5min
     
    2. transition resistance
    The transition resistance of the shield or monitoring layer should be no greater than 3kΩ.
     
    3. combustion test
    Cables shall be subjected to the combustion test.
     
    4. partial discharge test
    1.5U0 discharge is not more than 20PC
     
    5. dielectric loss tangent test
    U0 is not more than 0.035.
     
    6. impulse voltage test
    95°C, 60KV positive and negative character each 10 times, the cable pattern processing frequency 11KV voltage, 15min.
     
    7. cable should be able to withstand 3U, 4H power frequency voltage test
