China transformers, single phase transformer, three phase transformer

Products Information

SG series three-phase dry transformer
SG series three-phase dry transformers are that since the air is cold or air-cooled in the voltage transformer cooling way of the type. Power frequency is 50-60HZ. It does not exceed 600 volts to input the voltage.

The dry-type transformer have been designed and produced by our factory for over 15 years. It is suitable used for electric circuit of AC 20Hz to 400Hz and voltage below 1000V, and is wide used in electric Used in the industrial, mining enterprises, power plant, airport, skyscraper etc fire prevention and require the higher place. For lighting electric facilities, the power of motive force, the power of rectification is used.  The specifications can be designed and satisfied for custom's special requirement.

Features and benefits:

• High level of isolation
• High quality neutral-ground bond
• High level of common-mode noise rejection
  Conversion from Delta to Wye or the other way around
• Easy to change voltage taps
• Custom design for specific system

Operating environment
1)Temp.:The ambient temperature can not over +40℃。
2)Altitude: Mounting location can not exceed the altitude of 2000m
3)Relative humidity: Maximum 90%
4)The site not attack by rain and snow
5)The medium which no explosion danger,no corroding metal,no electrical breakdown
