Conductor bars for the stator winding of an electrical machine are impregnated by winding the bars with an insulation, impregnating the insulation, and then curing. Specifically, the bars are provided on their surface with an insulation which is produced by wrapping each conductor bar with an insulating tape, preferably with a mica-containing insulating tape, which is impregnated with an insulating fluid, preferably curable synthetic resin. Each conductor bar provided with the finished insulation is provided over its entire length with a press-tight and fluid-tight casing. The encased conductor bar is subjected on all sides to a pressure p1 in a pressing device. The impregnating fluid is introduced into the interspace between the insulated conductor bar and the casing at a pressure P2<P1. The conductor bar, loaded with impregnating resin over its entire length in this way and surrounded by the casing, is pressed to shape and size at the curing temperature.
