12kV Surge Arrester

Metal oxide 12kV surge arrester is the most advanced over-voltage protector at present in the world



What is a Surge Arrester?

A surge arrester is a device that is used to protect electrical equipment from overvoltage surges. Electrical surges and lightning strikes can damage electrical equipment, resulting in costly repairs or even system failure. The surge arrester protects electrical equipment by diverting the surge away from the system, reducing the risk of equipment failure.
