Product Description

metal oxide varistor:

Zinc oxide resistor is the core of the arrester, which main component is Zinc Oxide and with a small quantity of Oxide bismuth, oxide fluoride , manganous carbonate, oxide antimony and other gleam of additive and made with high temperature,It is a lightning protection equipment with superior protection performance, light weight, pollution resistance and stable performance. It mainly utilizes the good nonlinear volt-ampere characteristics of zinc oxide, so that the current flowing through the arrester at normal operating voltage is extremely small (microampere or milliampere level); when overvoltage is applied, the resistance drops sharply, and the overvoltage is discharged. Energy to achieve the effect of protection.

The difference between this arrester and the conventional arrester is that it has no discharge gap and utilizes the nonlinear characteristics of zinc oxide to function as a discharge and break.
