1. Versatile Applications: Ideal for local lighting, high-rise buildings, airports, terminals, CNC machinery, and equipment.
2. Dry-Type Design: Core and windings are not immersed in insulating oil, enhancing safety and reducing maintenance.
3. Cooling Options: Offers both natural air cooling (AN) for continuous operation at rated capacity and forced air cooling (AF) to boost output capacity by 50% for intermittent or emergency overload operations.
4. Economic Operation: Efficient operation under normal conditions, with the flexibility to handle temporary overloads, although not recommended for long-term continuous overload due to increased load loss and impedance voltage.
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and equipment, etc. Simply put, dry-type transformers refer to transformers whose core and windings are not immersed in insulating oil.
Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at rated capacity. When forced air cooling is used, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; because the load loss and impedance voltage increase greatly during overload, it is in a non-economic operating state, so it should not be placed in long-term continuous overload operation.
