    Model: FCGW-35KV / (630-2000) A
    Rated voltage: 35kv
    Rated current: 630 ~ 2000A
    Product certification: ISO9001

    I. Through-wall bushings_application scope and characteristics

    FCGW composite wall bushing is outdoor-indoor type, suitable for power distribution devices of three-phase AC system power stations and substations with a rated voltage of 10KV ~ 35KV and a frequency of 15 ~ 60Hz. The ambient temperature of the installation site is -40 ℃ ~ 40 ℃, and the altitude does not exceed 1000m. This product is suitable for horizontal installation.
    Various electrical and mechanical properties of the composite wall bushing have reached the standard requirements. He also has the common characteristics of composite insulators . Small size, light weight and beautiful appearance, especially the silicone rubber umbrella skirt used as external insulation, the jacket has good hydrophobic and hydrophobic migration characteristics, which makes the composite wall bushing have good anti-fouling performance and prevent Pollution Flash Ability.

    Product model description:


    Structure and performance

    The composite wall sleeve is composed of a cylindrical guide rod and an epoxy fiber layer tightly enclosing the guide rod, an intermediate flange, and a silicone rubber sheath and an umbrella skirt encapsulating the epoxy glass fiber layer. Evenly processed. This series of products are produced in accordance with Q / GND-JD05-2003 and combined with the relevant regulations of GB / T12944.1-1991, GB / T12944.2-1991 and J85892-1991. Its main dimensions and electrical and mechanical characteristics are shown in Tables 1 and 2.
