33KV 5KA Polymer Housing Metal Oxide Surge Lightning Arrester for Substation
Brief Description:
Polymer Housed Metal-Oxide Surge Arrester is mainly applicable for protection of the power equipment like transformers against system over-voltages and lightning surges. It is manufactured with excellent voltage-ampere characteristics and high level of reliability and durability. And the arrester is designed and type tested according to IEC60099-4:2004 standard.
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.
Main 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
Apply Area:
1. Distribution networks
2. Transmission line
3. Substation
4. Railway power station
5. Alternator and electromotor
