Abstract: The disclosure is related to a dry transformer, which includes a transformer core with at least two parallel limbs and upper and lower yokes, and at least two hollow cylindrical coils, each arranged as neighbored coils around a limb of the at least two parallel limbs. A cooling system can include at least one wall-like diaphragm in-between the neighbored coils, which is in parallel to the orientation of the limbs.

Abstract: A dry-type transformer heater includes a closed housing, and at least one transformer winding arranged in the housing. The at least one transformer winding includes at least one corresponding winding conductor and a corresponding insulation layer surrounding the transformer winding, respectively. In addition to the respective winding conductor, at least one coil heating wire is provided in at least one of the insulation layer and on the surface of the insulation layer to input thermal power into the respective insulation layer.
