Dry-type transformer has the advantages of large short-circuit resistance, little maintenance work, high operation efficiency, small dimension and low noise, which is commonly used in places with high requirements of fireproof and explosion-proof. This type transformer is widely used in local lighting, high buildings, airports, docks, CNC machinery and others. Its cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). The transformer can operate continuously for a long time under rated capacity under natural air cooling. Output capacity of the transformer can increase by 50% under forced air cooling. It is suitable for intermittent overload operation or emergency overload operation. Due to the load loss and impedance voltage increase significantly when overload, it is not suitable for long time continuous overload operation.
