Product Description
Product Description
 Zinc Oxide Lightning Arrester
1.Zinc Oxide lightning arresters are good protection performance. that the normal working voltage of the current flow through the arrester (a minimum or MA); 
3.when the voltage, resistance fell sharply, let go of the voltage of the discharge energy, protect effect. 
4.The differences of lightning arrester and traditional lightning arrester is that there is no gap, the nonlinear characteristics of the zinc oxide to discharge and breaking effect

Main principie
Zinc-oxide lightning 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 energv to effectively protect the power transmission equipments from damage caused by over voltage.

Application and features
Zinc-oxide lightning arrester is protective equipment for electrical devices in A.C.power system from damage caused by over voltage or over-voltage operation.
