9KV Gapless Metal Oxide Surge Arrester Polymer Self - Standing with KEMA Certified

9kV Polymeric Gapless Lightning Arrester with KEMA


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.


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


Applications:


1. Distribution networks

2. Transmission line

3. Substation

4. Railway power station

5. Alternator and electromotor
