ABSTRACT OF THE DISCLOSURE: A sheet winding in a transformer is made with double-curved conductor sheets. Some of the winding turns are mutually different as regards the curvature visible in an axial section. This has been achieved by arranging a number of filling members at each one of the end surfaces of the winding. Each filling member contains several turns of a filling tape, which are evenly distributed in a group of mutually adjacently positioned winding turns wound from a conductor sheet. Because the filling tape has different degrees of overlap in the different turns of the conductor sheet, the filling member will have approximately the same effect as a filling body which, in axial section, exhibits a wedge-shaped cross-section area.
