What Is a 250 kVA Oil Immersed Transformer?
A 250 kVA Oil Immersed Transformer is a medium-capacity distribution transformer that uses insulating oil for cooling and dielectric protection. The oil effectively transfers heat from the core and windings to the tank surface, ensuring stable performance during continuous industrial operation.
Typical Technical Data of 250 kVA Oil Immersed Transformer
- Rated Capacity: 250 kVA
- Phase: Three Phase
- Primary Voltage: 10kV / 11kV / 20kV / Customized
- Secondary Voltage: 0.4kV or customized
- Cooling Method: ONAN
- Frequency: 50Hz / 60Hz
This configuration makes the transformer ideal for industrial power systems with steady and variable loads.
