Norway 20KV dry-type transformer

Product Description
20k dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). During natural air cooling, the transformer can operate continuously at rated capacity for a long time. During forced air cooling, the transformer's output capacity can be increased by 50%. Suitable for intermittent overload operation; or emergency overload operation. Because the load loss and impedance voltage increase significantly during overload, it is in a non-economic operating state, so it should not be allowed to operate continuously under overload for a long time.
