Highlight:
21kV,5kA polymer lightning arrester/surge arrester

Single Phase Silicon Rubber Lightning and Power Surge Arrester for Electrical Equipment

 

Specifications:

 
Composite Surge Arresters can be applied to a variety of systems including substation equipment, AC-DC converters, railway power system and power distribution units ranging from 0.25kV to 765kV systems. These surge arresters demonstrate excellent protection properties. Metal oxide type surge arresters offer such special features inherent in the gap-less structure, such as a quick response to surge voltage, high energy dissipation capability, safe operation, compactness / lightweight and freedom from pollution.
