zinc oxide lightning arrester

zinc oxide lightning arrester is to protect electrical equipments in power system from damage of over voltage and high voltage.

          zinc oxide lightning arrester

 Zinc oxide arrester is a king of world advanced over-voltage and high voltage protector at present,due to its core components of resistance applying Zn and other metal oxide,which greatly improves V-A characteristics of resistance,increases the passing current ability of resistance,thereby it brings fundamental change to feature of arrester.
