The corona-shielding arrangement for the stator winding of an electric machine, comprising a semi- conductive textile corona-shielding strip wound around the major insulation of slot portion and end yoke portion of each bar of the stator winding is con- structed such that the slot portion (10) of the stator winding bar is wound around in at least one layer with a first semiconductive, volume-conducting corona- shielding strip (24) having an approximately constant degree of overlap. The end yoke portion is wound around in at least one layer with a second semiconductive, volume-conducting corona-shielding strip (24), the degree of overlap from the exit of the bar from the stator body (14) to the bar end becoming continuously smaller. This corona-shielding arrangement is economic to produce; the voltage characteristic in the longitu- dinal direction of the bar is simple to optimize.
