Product Details

Product description

Volcano 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.

Working condition:

1)Environment temperature: -40--+40 degree
2)altitude: <1000m
3)48HZ
4)Power frequency voltage should not be more than continuous running voltag
5)Max wind speed should be less than 35m/s
