Dry type transformer

Dry type transformers are widely used in local lighting, high-rise buildings, airports, dock CNC mechanical equipment, and other places. Simply put, dry type transformers refer to transformers with iron cores and windings not immersed in insulation oil.

The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). During natural air cooling, the transformer can operate continuously for a long time at rated capacity. When forced air cooling is applied, the output capacity of the transformer can be increased by 50%. Suitable for intermittent overload operation or emergency accident overload operation; Due to the significant increase in load loss and impedance voltage during overload, it is in a non economic operating state, so it should not be subjected to long-term continuous overload operation.
