Composite Metal Oxide Surge Protectors without Gaps of Low Voltage

Description:

Metal oxide 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.

Applications:

1. Distribution networks

2. Transmission line

3. Substation

4. Railway power station

5. Alternator and electromotor

Specifications:

Working condition:

1) Environment temperature: -40--+40 degree
2) altitude: <1000m
3) 48HZ

4) Power frequency voltage should not be more than continuous running voltag
5) Max wind speed should be less than 35m/s
6) Earthquake intensity should be less than 7 degree
7) If used in contamination area, should be noted in advance.
