Description

The metal oxide surge arrester is the most advanced over-voltage protector in the world, due to make the resistor disc of core component mainly adopt zine oxide arrester, compared with the conventional siliconcarbide arrester,  this presciption of the product improves greatly the volt-Ampere charateristics of the resistor disc and increased through-current capability at over-voltageso as to bring a radical changes for the characteristics of the arresters.
