Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, and CNC machinery. Simply put, a dry-type transformer is one whose core and windings are not immersed in insulating oil.

Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). With natural air cooling, the transformer can operate continuously at its rated capacity for extended periods.

With forced air cooling, the transformer's output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; however, because load losses and impedance voltage increases significantly under overload conditions, resulting in uneconomical operation, it should not be subjected to prolonged continuous overload operation.

Dry-type transformers are mainly classified into three types: open-type, enclosed-type, and cast-resin type.

Currently, our company produces S11, S13, S20, and S22 series 10kV and 35kV oil-immersed power transformers; SCB11, SCB12, SCB14, and SCB18 series 10kV and 35kV epoxy-cast dry-type power transformers; SH15, SH21, SH25, SCBH15, SCBH21, and SCBH25 type amorphous alloy power transformers; ZGS type combined substations; YB prefabricated substations; photovoltaic box-type substations and prefabricated cabins.
