Brief Description:</s

33KV 5KA Polymer Housing Metal Oxide Surge Arrester for Substation YH5W5-33

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
