Product Details

Metal Oxide Varistor is the core of the arrester,which main component is Zinc Oxide and with a small quantity of bismuth oxide,Silicon.Oxide,
cobalt.oxide,nickel.oxide fluoride oxide,manganous carbonate,antimony oxide and other gleam of additive and made with high temperature.
Metal Oxide Varistor’s microstructure mainly constitute of Zinc Oxide grain,grain boundary layer and Chienshih phase. Ard 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. Varistor’s nonlinearity mainly comes from grain boundar layer (the main ingredient is bismuth oxide) Chienshih 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.
