Service Environment

1. The ambient temperature is not higher than +40ºC, not lower than -40ºC;
2. Radiation from sunlight:
Note: The effect of maximum solar exposure (1.1kw/m2) has been taken into account by preheating the test in the type test. If there are other heat sources in the vicinity of the arrester, the use of the arrester must be negotiated by the supply and demand parties.
3. The altitude does not exceed 3000m;
4. The frequency of the power supply is not less than 48Hz, not more than 62Hz;
5. The power frequency voltage applied between the terminals of the arrester for a long time should not exceed the continuous operating voltage of the arrester;
6. Earthquake intensity degree 7 and below;
7. The maximum wind speed does not exceed 35m/s.
