Arrester resistor

Commodity name： Arrester resistor

Product Details

Metal oxide resistor is the core part of lightning arrester. It is sintered at high temperature with zinc oxide as the main component and a small amount of bismuth oxide, cobalt oxide, chromium oxide, manganese carbonate, antimony oxide and other trace additives.
The microstructure of metal oxide resistance sheet is mainly composed of zinc oxide grain, grain boundary layer and spinel phase. The conductive mechanism is generally considered as follows: zinc oxide grains have good conductivity, almost all the voltage applied to zinc oxide grains acts on the high resistance grain boundary layer, the nonlinearity of the resistance sheet mainly comes from the grain boundary layer (with bismuth oxide as the main component), and the spinel phase is scattered in the boundary layer, which is a composite oxide composed of zinc oxide and bismuth oxide. Its function is to inhibit the growth of zinc oxide grains, so that the resistor has
Better nonlinear characteristics. Zhejiang Beitai High Voltage Electrical Appliance Co., Ltd. is a large backbone enterprise specializing in the production of resistor and varistor for lightning arrester. It is the largest producer of zinc oxide resistor in China. The company has the most advanced automatic production line of large zinc oxide resistor and automatic detection line of electrical parameters of resistor. The production process of the resistor adopts the production process line introduced by Hitachi Company in Japan. The external insulation process adopts the internationally popular glass glaze process. The company annually produces 700 tons of Zn0 granulation material, equivalent to more than 5 million pieces of D3 zinc oxide resistor. The export type arrester produced by our company has passed the certification of KEMA Laboratory, the world famous authoritative testing organization.
