Detailed Description

6kV Silicon Rubber Surge Arrestors 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.
