Gapless ZnO surge arrester with porcelain housing:
The Zinc Oxide surge arrester protects the electrical equipment in AC power systems against damaging atmospheric over-voltage and operating over-voltage.
The surge arresters comply with IEC60099-4&IEEE.C62.11 standard technical requirements.
Working conditions
1. The ambient air temperatures is no higher than + 0°C, no lower than -40°C.
2. The altitude above sea level does not exceed 1000-2000m (the plateau area should be indicated when order).
3. AC system frequency 50Hz or 60Hz.
4. Power frequency voltage brought to bear on arrester for a long time does not exceed arrester's continuous operation voltage.
5. Maximum wind speed does not exceed 35m/s.
6. The earthquake intensity does not exceed 7 degrees.
