Application

SG series single-phase and three-phase dry type transformer adopts high quality material and advanced technology, it has advantages of damp-proof and convenient, like underground railway, high building, airport, station, wharf, enterprise, tunnel, etc.

It is mainly used in power supply occasions of AC50-60Hz and voltage, connection group and capacity of trapped winding can be designed and produced according to users' requirements.

Model and Meaning

Working conditions

1.Ambient air temperature: -5°C~+40°C, the highest monthly mean temperature should not exceed +30°C;

2.Altitude for installing place should not exceed 2000m;

3.When the ambient air temperature is +40°C, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is + 25°C, and condensation on the product surface caused by temperature change should be taken into consideration.
