Over-voltage Protector
Over-voltage Protector

Over-voltage protector is to protect electrical equipments in power system from damage of over-voltage and high-voltage.

  

 
Type" over-voltage protector  over-voltage protector 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:
