Abstract

A transformer winding, having at least two multi-layered winding modules, which are connected electrically in series, extend about a common winding axis, and are nested one inside the other hollow-cylindrically, at least one cooling channel, which is arranged along the common winding axis hollow-cylindrically between the winding modules, and a flat electrical shield is provided within the at least one cooling channel at least sectionally along the radial circumference thereof, wherein the electrical shield extends over approximately the entire axial length and through which electrical shield the electrical capacitance distribution in the transformer winding connected electrically in series is influenced.
