Power Station Lightning Current Silicon Rubber Material Surge Arresters
Description:
YongDe 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. 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
Operating 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
6) Earthquake intensity should be less than 7 degree
7) If used in contamination area, should be noted in advance.
