In a high-voltage insulated stator winding having at least one stator winding bar (10) for an electrical machine, which stator winding bar (10) is surrounded by winding insulation (13) which comprises a plurality of insulating layers (22) arranged one above the other, in which case each insulating layer (22) is composed of an insulating material arranged on a base (16), in particular in the form of Mica paper (14), improved dielectric utilization (withstand voltage) and improved thermal utilization (heat dissipation) are achieved to an equivalent extent in that a heat-resistant plastic film is used as the base (16), which plastic film is modified by introducing a filler which can resist corona discharges.
