Abstract
A winding bar (10) for a high-voltage winding, for example a stator winding of an electric machine, includes a plurality of conductors (13) which are arranged above and/or next to one another in a conductor bundle. The conductor bundle has a rectangular cross section. The conductor bundle is surrounded by an insulation (14). An overall improved electric strength is achieved at the edges without changing the insulation thickness because a thickness (d2) of the insulation (14) on the edges (15) of the winding bar (10) is greater than the thickness (31) of the insulation (14) on the flat sides of the winding bar (10). Preferably, a calibration process is used to shape the edge region.
