The transformer body is placed in the IP54 cabinet, which can be used in places with complex site environment (such as corrosive gas, serious dust, conductive particles, etc.);

The dry-type rectifier transformer for afwf variable-frequency speed regulation is cooled by air-water heat exchanger. With special air duct design, the fan draws out the hot air of the transformer, cools it by air-water heat exchanger, and then sends the cooled air to the air inlet of the transformer, so as to solve the heat dissipation problem of the transformer without exchange with external air;

It has high insulation level, small partial discharge and long product life; it can be decomposed and recycled after environmental protection life, which lays a solid foundation for building circular economy. The dry-type rectifier transformer for forced air-cooled variable-frequency speed regulation is easy to overheat when the capacity exceeds 14000KVA due to insufficient heat dissipation. Afwf dry-type rectifier transformer for variable-frequency speed regulation is more suitable for making large capacity transformer, which can effectively solve the disadvantages of ordinary air-cooled transformer. By solving the problem of heat dissipation, all aluminum coil design can be used for products above 8000kVA.
