Dry-type transfomers are widely used in local lighting, high-rise buildings, airports, wharf CNC machinery and other
places. Simply speaking. dry-type transformers refer to transformers in which iron cores and windines are not immersedin insulating oil Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). During natural aircooling, the transtormer can operate continuously for a long time at rated capacity. When forced air cooling occurs, theoutput capacity of the transformer can be increased by 50% Suitable for intermittent overoad operation or emergencyoverload operation; Since the load loss and impedance voltage increase greatly during overload and are in non -economic operation, it should not be kept in continuous overload operation for a long time.
