Substation Composite Metal Oxide Surge Lightning Arrester Lightweight Protection Device
Description:
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.
Features:
1. Compact and Lightweight
2. Extremely Safe Pressure Relief Performance
3. Superior Performance against Environmental Contamination
4. Directly Molded Structure
5. Compliance with International Standards(IEC60099-4)
6. Simple Support Structure
7. Manufactured at Advanced ISO-9001 certified facilities
