Abstract
A Roebel bar () for an electrical machine comprises a plurality of essentially parallel, transposed conductor elements (), which, lying over and/or next to one another, form a bar with an essentially rectangular cross section, which is surrounded on the outside by an insulation () and has between the insulation () and the conductor elements () means () for forming an inner corona protection (ICP). In the case of such a Roebel bar, particularly effective inner corona protection is achieved by the fact that the means for inner corona protection comprise preformed, angled profiles () of an electrically conducting material, which, running in the longitudinal direction of the Roebel bar (), enclose the edges of the bar formed by the conductor elements (), and to which the insulation () is applied.
