12-pulse dry-type transformer cooling methods are divided into natural air cooling (AN) and forced air cooling (AF).

Under natural air cooling, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%.

It is suitable for intermittent overload operation or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be in continuous overload operation for a long time.
