Zinc-Oxide MOV Surge Arrester
Model : YH10W-12
Brand : Nanyang Jinniu Electric Co., Ltd.
Zinc-oxide MOV surge arrester is the most advanced over-voltage protector at present in the world. The voltage current characteristic of the varistor has been changed compared with traditional carborundum arresters due to the multiple metal oxide materials application in the core element-varistor, which has greatly improved the varistor’s throughput capacity and brought thorough change to arresters’ characteristics. When arrester is under normal voltage, there is only microamp current through it. When it is under high voltage, arresters’excellent nonlinear voltage current feature gets into play, so the current through arresters will reach thousands of amperes and the arresters are at conducting status, releasing over-voltage energy to effectively protect the power transmission equipments from damage caused by over voltage.
