    GB 11032 Polymer Lightning Surge Arrester Gapless For Electrical Railway

    Railway Polymer Gapless Surge Arrester


    Product introduction:

    Polymer-housed metal oxide surge arrester (MOA) combines advantages of organic insulation material and porcelain-housed MOA. It is of good electrical performance, high dielectric strength, resistance to high/low-temperature, to aging, as well as explosion-proof, excellent chemical stability, and hydrophobicity. Polymer housing is made of high-quality silicone rubber, formed by integral moulding and curing process which benefites sealing performance, service life and lead time.
    Metal oxide varistors are wrapped and fixed by PBT, after that a varistor rod shall be processed by vulcanizing machine into a completed surge arrester. This kind of uniq technics greatly improves SA electricl performance and shorten production time.
    Advantage:
    1/ Low partial discharge;
    2/ Low residual voltage;
    2/ High dielectric insulation level;
    3/ Tolerance to high/low temperature;
    4/ Explosion-proof;
    5/ Anti-corrosion;
    6/ Anti-aging;
    7/ Shorter lead time (Ex-work 1 week+).
    Standard Technical Data:
    Below info. only for your reference, all data shall be specified and determined by technical specification and customer demand.
