ABSTRACT:
The corona-shielding arrangement for the stator winding of an electric machine, comprising a semiconductive textile corona-shielding strip wound around the major insulation of slot portion and end yoke portion of each bar of the stator winding is constructed 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 coronashielding 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 longitudinal direction of the bar is simple to optimize.
