The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through-current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.

Surge arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lighting impulse voltage and operated over-voltage.
