The Characteristic Structure Of Dry Type Transformer

Temperature control system

The safe operation of dry transformer and its service life depend greatly on the reliability of the insulation of transformer windings.

Cooling way

Dry transformer cooling is divided into natural air cooling (AN) and forced air cooling (AF).

In natural air cooling, the transformer can run continuously at rated capacity.

The output capacity of transformer can be increased by 50% when forced air cooling.

It can be used for intermittent overload operation or emergency overload operation.

Because load loss and impedance voltage increase greatly in overload, it is in non-economic operation state, so it should not be in a long time continuous load operation.
