Abstract:
An electrical machine (40) comprising at least one stator winding (10) with a winding wire (1) comprising a conductor (2), and an insulation layer (3) surrounding the conductor (2) along a longitudinal direction thereof. A conductive layer (4) surrounds the insulation layer (3) along a longitudinal direction thereof, and the conductive layer (4) is grounded. By providing a winding wire (1) with a conductive layer (4) surrounding a conventional insulation layer (3), important prerequisites for both bearing currents and partial discharges are removed from the stator winding (10), thereby enabling increased voltage levels in stator windings without further additional measures required for deviating bearing currents.

The conductor arrangement including an electrical conductor (101); and an insulation being provided around the electrical conductor (101) and including at least one mica tape layer (110; 110-1; 110-2) and at least one impregnation resin layer (120; 120-1; 120-2), wherein the at least one mica tape layer and the at least one impregnation layer contain a resin mixture. The insulation includes a catalyst for curing the resin mixture and a catalyst-activating agent (230) activating the catalyst. The concentration of the catalyst-activating agent (230) is greater in the mica tape layer than in the impregnation resin layer and the concentration of the catalyst per resin unit of the respective layer is substantially the same in the mica tape layer and in the impregnation resin layer.
