High-performance Metal Oxide Zinc Varistor Disc Manufacturers


Brief Description:


Metal oxide Varistor For surge arrester


Zinc oxide varistor is the core of the arrester,which main component is Zinc Oxide and with a small quantity of bismuth oxide, fluoride oxide, manganous carbonate, antimony oxide and other gleam of additive and made with high temperature.


Metal oxide Varistors microsturcture mainly constitute of Zinc Oxide grain, grain boundary layer and chienship phase. And its electric conduction principle lies that Zinc Oxide grain has good electro conductibility, and the voltage to the Zinc Oxide is almost act on high resistant grain boundary layer. Varistors nonlinearity mainly comes from grain boundary layer(the main ingredient is bismuth oxide) chienship phase scattered throughout the grain boundary layer which is the multiple oxide of Zinc Oxide and bismuth oxide. Its function lies in restraining the growing of Zinc Oxide grain to make the better nonlinearity.

Zinc Oxide Varistor is widely used in large filed of lightening protection,they are

specified according to the voltage range that they can tolerate without damage.

Other important parameters are the varistor's energy rating in joules, operating

voltage, response time, maximum current, and breakdown (clamping) voltage.

Energy rating is often defined using standardized transients such as 8/20

microseconds or 10/1000 microseconds, where 8 microseconds is the transient's

front time and 20 microseconds is the time to half value.
