Abstract
A large electrical machine, includes bar windings composed of twisted individual conductors with irregularities formed at the narrow edges of the bar winding. The bar winding is composed of individual insulated conductors and uninsulated conductors. A synthetic mica-resin putty pressed between the conductors fills the spaces between the conductors. Electrically conductive strips covering the putty are electrically connected to the uninsulated conductors.
