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： A method for manufacturing a liquid-cooled stator bar suitable for use in a generator. The method includes providing a stator bar comprising a plurality of conducting strands collectively formed into a desired shape, wherein at least one of the conducting strands is configured to channel a liquid for cooling the stator bar. At least one layer of ground wall insulation is applied to the outer portions of the stator bar, and then at least one layer of a conductive tape is applied to an outer area of the ground wall insulation. The ground wall insulation and the conductive tape are cured.
