Feature: 

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.
