Applications：
Provide lightning protection and over-voltage protection, can effectively ensure the safe operation of the power grid.
Features：
Surge arrester with a unique escape from the explosion-proof device (ejector arrester valve).
Can effectively prevent arrester valves from aging off moment, the ground to form a high voltage and external shield to form a pathway discharge.
