Abstract: A rotating electrical machine and method for making the machine, where the machine includes a high-voltage stator winding and elongated support devices for supporting the winding. The machine and method employ an arrangement of cable that is made of inner conductive strands, covered with a first semiconducting layer, which is covered with an insulating layer, which is covered with a second semiconducting layer. The cable is wound in slots in the stator such that separate cable lead-throughs are positioned in specific arrangements with respect to each other and in slots of the stator. The arrangement of the cable in the stator protects the integrity of the respective components in the cable and particularly the second semiconducting layer.

Abstract: A rotor machine arrangement comprises a rotor, a stator, at least one guide vane, which at two opposite ends is supported by the stator, and at least one end is pivotably arranged relative to the stator in at least a first plane, and at least one conducting member arranged to conduce a fluid into the guide vane for influencing the temperature of the same. The rotor machine arrangement comprises a sealing element which is pivotably connected with the guide vane in at least a second plane, is arranged to seal between the stator and the guide vane, and the sealing function of which is essentially independent of the angular position between the guide vane and the stator in said first plane.
