A dry-type transformer is a type of transformer that does not use liquid cooling agents. Unlike traditional oil-immersed transformers, dry-type transformers use air as the cooling medium, thus eliminating safety hazards such as oil leakage and explosion. It is widely used in local lighting, high-rise buildings, airports, docks, CNC mechanical equipment and other places.
The cooling methods are divided into Natural Air Cooling (AN) and Forced Air Cooling (AF). During natural air cooling, the transformer can operate continuously at the rated capacity. When using forced air cooling, the output capacity can be increased by 50% for intermittent overload or emergency operation.
