摘要： Disclosed is an electric-machine stator bar winding provided with an arrangement for electric insulation of end connections of extreme bars of different phase winding groups, that comprises box-type dielectric screens encompassing said connections. Each of the screens is built up of channel-shaped members made from a thermosetting material and having bent end portions. These members are so installed that adjacent walls of a pair of the screens in one interphase region of the end windings, lying in the radial planes of the stator are formed by adjoining walls of the angle-shaped members, the walls of the screens which are opposite to the adjoining walls are formed by the walls of the channel-shaped members, whereas the walls of the screens, lying in the tangential planes of the stator are formed by the flanges of the channel-shaped and angle-shaped members, the bent end portions of these members adjoining a part of involume sections of the bar end portions. The end windings have members used for tangential fastening of the bar end portions, which members are made from an electrically insulating moulding material, arranged in the interphase regions, and entering the regions of arrangement of the involute sections of the bars.
