Abstract: A strip winding for a transformer includes a plurality of winding modules each having a strip conductor wound around a winding axis. A winding segment is formed by at least two radially adjacent winding modules. At least one cooling channel extending in the axial direction is provided between at least two radially adjacent winding modules. At least two axially adjacent winding segments are provided, and the winding modules are connected electrically in series by connecting conductors. At least one connecting conductor is led at least in sections through the cooling channel along the axial extension of the cooling channel.

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.
