摘要： A device and a method for stabilizing an elongated metallic strip of a magnetic material when coating the strip with a metallic layer. The strip is transported from the bath in a direction of transport along a predetermined transport path. A wiping device for wiping off superfluous molten metal from the strip applies an air flow in a line across the strip, where the wiping device includes at least one pair of air-knives arranged with one air-knife on each side of the strip. An electromagnetic stabilizing device stabilizes the position of the strip with respect to the predetermined transport path. A sensor detects the position of the strip in relation to the predetermined transport path.

摘要： 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.

摘要： The magnetic circuit of a generator in a hydro-generator plant is arranged to directly supply a high supply voltage of 20-800 kV, preferably higher than 36 kV. The generator is provided with solid insulation and its winding includes a cable (6) comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by at least one outer and one inner semiconducting layer (34, 32) and intermediate insulating layers (33). The outer semiconducting layer (34) is at earth potential. The stator winding may be produced with full or fractional slot winding, the phases of the winding being Y-connected. The Y-point may be insulated and protected from over-voltage by means of surge arresters, or else the Y-point may be earthed via a suppression filter. The invention also relates to a hydro-generator plant, a generator included in the plant and a procedure for building such a plant.

摘要： A conductor and a rotating electric high-voltage machine that includes the conductor has a cable configured for high-voltage operation. The cable may be included as a winding for the rotating electric high-voltage machine. The conductor includes a first strand that is clad with an electrically insulating layer, and a second strand that is uninsulated whereas the first strand and the second strand are arranged in two or more layers of strands. The two or more layers of strands are insulated from one another. Furthermore, the first and second layers of the two or more layers of strands are arranged around a central core where the central core is at least one of an air core and a core of another material. The second strand is positioned so as not to be electrically contacting any other uninsulated strand.
