Dry Type Distribution Transformer

Henan New Electric Power Co.,Ltd. is a comprehensive enterprise integrating product research and development, product sales, and import and export services. It has more than 45 years of research and development experience. The company has a modern workshop of more than 120,000 square meters, a research and development center, and a staff apartment of more than 30,000 square meters. The production equipment is perfect, the testing method is perfect, the technical force is strong, and the qualification is complete. We can provide high, medium and Low Voltage Transformers with voltages of 110KV and below and capacities of 120,000 kVA and below for various purposes, as well as tap changers, gas relays, oil level gauges, moisture absorbers, valves, thermometers, insulators, fans and other accessories .

Dry type transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC mechanical equipment and other places. Simply speaking, 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). In case of natural air cooling, the transformer can operate continuously for a long time under rated capacity. In case of forced air cooling, the output capacity of transformer can be increased by 50%. It is applicable to intermittent overload operation or emergency overload operation; Due to the large increase of load loss and impedance voltage during overload, it is in a non economic operation state, so it should not be in a long-term continuous overload operation.
