ABSTRACT:
A winding element for an electrical machine, in particular a turbogenerator, includes an electrically conductive conductor configuration for carrying an electric current, an insulating layer surrounding the conductor configuration and a protective configuration surrounding the insulating layer. The protective configuration includes an isolating layer disposed like a helix, and an at least slightly electrically conductive contact layer likewise disposed like a helix and overlapping itself. The contact layer traverses or passes through the isolating layer from an inner side facing the insulating layer to an outer side facing away from the insulating layer. A winding assembly for an electrical machine includes an electrically conductive winding support and a winding element circumferentially surrounded and electrically contacted by the winding support. A set has a plurality of such winding elements in which the conductor configurations are connected to one another and form a winding for an electrical machine, in particular a turbogenerator.
