A disc coil winding of interwound coils is formed of winding conductors covered with normal insulation, the winding having a radially inner and a radially outer surface. A plurality of the coils are disposed at an input to the winding, and have respective turns thereof located at the inner and the outer surface of the winding as well as respective turns thereof located radially adjacent thereto. Supplemental insulations are provided for reinforcing the normal insulation, the supplemental insulations extending from respective starting locations both between the turn located at the inner surface and the turn adjacent thereto as well as between the turn located at the outer surface and the turn adjacent thereto for protecting at least one edge of the respective turns. The coils have a turn capacitance between respective turns thereof free of the supplemental insulations which is greater than the turn capacitance between the respective turns thereof provided with the supplemental insulations. The supplemental insulations are formed as a spacer having a substantially rectangular cross section disposed radially between the respective turns to be supplementarily insulated, the spacer having a width in axial direction equal to the corresponding width of one of the winding conductors covered with normal insulation.
