30KVA EI/Square Type Three Phase Auto Transformer 380V/220V Air Cooling
Feature:
1. Ambient air temperature; minimum air temperature:-40℃.
2. Air relative humidity: The average monthly maximum relative humidity of the wettest month is 90%, and the monthly average minimum temperature of the month is 25℃, taking into account the condensation on the surface of the product due to temperature changes.
3. A place without significant shaking and shock vibration.
4. There is no explosion hazard in the medium, and there is no gas and dust (including conductive dust) in the medium that can corrode the metal and damage the insulation.
5. In a place where there is no rain or snow.
