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.
