Dry Type Transformer

Dry Type Transformer is widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil.
The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When the transformer is naturally cooled, it can operate continuously for a long time at the rated capacity. When forced air cooling, the transformer output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; because the load loss and impedance voltage increase during overload are large, it is in a non-economic operation state, so it should not be in long-term continuous overload operation.
