Easily Assembled Metal Oxide Rubber Gapless Surge Lightning Arrester with Disconnector
Lightning Arrester 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. These surge arresters demonstrate excellent protection properties. YongDe surge arresters incorporate YNR elements (YongDe Non-linear Resistor ZnO Elements) with superior non-linear voltage-current characteristics, high quality and reliability. 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.
Lightning Arrester 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
