Abstract
A conductor bar for a stator winding of a rotating electrical machine includes a bundle of parallel conductor strands extending between two ends of the conductor bar and spaced apart by interspaces. A main insulation is wound around the bundle of conductor strands and a stack separators fills at least part of the interspaces. Protection elements are between the bundle of conductor strands and the main insulation. At least one of the protection elements or the stack separators are configured to compensate, at least in part, thermal expansion of the conductor elements when temperature changes.
