Electric Power Surge Arrester

1. About Surge Arrester 

YONGDE Surge Arresters can be applied to a variety of systems including substation equipment,

railway power system and power distribution units ranging from 0.28kV to 500kV systems. 
These surge arresters demonstrate excellent protection properties. Our surge arresters incorporate

non-linear resistor ZnO elements with superior non-linear current- voltage characteristics,

high quality and reliability. Metal oxide type surge arresters offer such special features 
inherent in the gapless structure, such as a quick response to surge voltage,

high energy dissipation capability, safe operation, compactness / lightweight and freedom from pollution.
