Overview
Description:

The metal oxide resistor is the core part of the lightning arrester. It is made of zinc oxide as a main component, and is added with a small amount of cerium oxide, oxidized diamond, chromium oxide, manganese carbonate, oxidized bromine and other trace additives.

Our company has the most advanced large-scale production line of large-scale zinc oxide resistors, automatic detection circuit for electrical parameters of resistors, and the production process of resistors adopts the production process route of Japan Hitachi, and the external insulation process adopts the international popular glass glaze process.

Our company produces 700 tons of ZnO granules per year, equivalent to more than 5 million D3 zinc oxide resistors. The company's export-type lightning arrester for the production of resistors has passed the certification of the world-famous authoritative testing agency KEMA Labs in the Netherlands.
