48kv Silicone Polymer Housing Composite Metal Oxide Surge Arrester

Zinc oxide surge arrester is a lightning protection device with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good non-linear volt-ampere characteristics of zinc oxide to make the current flowing through the surge arrester at normal working voltage very small (microamp or milliampere level); when the overvoltage acts, the resistance drops sharply, venting the overvoltage Energy to achieve the effect of protection. The difference between this kind of lightning arrester and the traditional lightning arrester is that it has no discharge gap, and uses the non-linear characteristics of zinc oxide to discharge and break.
