ABSTRACT:
A Roebel bar for a rotating electrical machine includes a straight slot part disposed in a slot in an iron sheet of a stator of the rotating electrical machine and a bent yoke part adjacent to the straight slot part and protruding from the stator, wherein the bent yoke part is configured to connect the Roebel bar to at least one more Roebel bar so as to form a winding. A copper conductor disposed in the straight slot part and the bent yoke part is surrounded by an insulation having an outer surface. A slot corona shielding includes an electrically conductive layer disposed on the outer surface of the insulation in an area of the straight slot part. A yoke corona shielding includes a semiconducting layer disposed on the outer surface of the insulation in an area of the bent yoke part.
