    Over Voltage Metal Oxide Gapless Lightning Arrester Ceramic For Electric Railway Systems


    1, Lighting Arrestor Description

    The lighting arrestor is the most advanced over-voltage protector. It is widely used as protective
    devices against switching and lightning over voltages in power electrical systems such as power
    transformers ,distributors,generators, compensation capacitors. Its core component--resistance slice adopts the material including zinc oxide and many kinds of metal oxides, compared with traditional silicon-carbide arrester,its volt-ampere characteristic of resistance slice has been improved to great degree, as well as the
    current-transmit ability of resistance slice, as a result, the capability of arrester has been improved basically
    and thoroughly.

    2, The metal-oxide surge arresters without gaps for electric railway, which is used to protect
    all kinds of electrical equipments, contact network, electric locomotive from the damage of
    atmosphere overvoltage and operating voltage.
