摘要： Resin-impregnated sheet materials, such as fabrics, films, paper and tapes, for forming electrical insulation that exhibits significantly improved voltage endurance performance. The present invention finds particular use as groundwall insulation for high voltage generator stator bars, in which the groundwall insulation is formed by mica tape filled with submicron particles of silicon dioxide, aluminum oxide, titanium dioxide and/or zirconium dioxide, in combination with an unfilled mica tape impregnated with the same or compatible resin binder. The filled tape is preferably in the form of a mica paper having at least one woven fabric on at least one of its surfaces, a resin binder permeating the mica paper and woven fabric so as to bond the woven fabric to the mica paper, and oxide particles dispersed in the woven fabric.

摘要： An electrical machine includes a stator having a radically inwardly directed duct adjacent the center of the machine for flowing cooling medium into the gap between the stator and rotor. The rotor includes radial or diagonal ducts having scoops for directing flow generally radically inwardly to cool the field windings in the center of the machine. The cooling medium flows either into subslots for radial or diagonal outward flow through outlet ducts for return to the gap.
