Lightning arrester is to protect electrical equipments in power system from damage of over voltage and high voltage. Type:Zinc oxide lightning arresterZinc oxide lightning 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. The main technical parameter:
