ABSTRACT:
A direct-cooled layer winding for transformers is formed of a plurality of helically wound tapes, the tapes in successive layers being directed backwards and forwards in the axial direction so that the turns of successive layers form angles with each other. At least one cooling layer is arranged coaxial with the winding between two of the tape layers. The cooling layer is formed of a tubular cooling conductor which is helically wound into a complete layer with the inlet and outlet at the opposite ends of the winding.
