    Abstract: A method for making a dynamoelectric machine conductor bar, compromises providing a plurality of bundled together spiraling strand conductors having surrounding insulation to define a substantially rectangular shape with the strand conductors and strand insulation defining an opposing conductor bar end portion having an electrically insulated gap between the strand insulation adjacent the bar end portion; and applying a filler material to fill the gap to electrically shield the conductor bar end portion and to a greater than 0.080 to about 1.5 inch continuous outer radius surface end portion. A dynamoelectric machine conductor bar comprises a plurality of bundled together spiraling strand conductors having surrounding insulation to define a substantially rectangular shape, with the strand conductors and strand insulation defining an opposing conductor bar end portion; an electrically non-insulated gap between the strand insulation adjacent the conductors at the bar end portion, and an applied filler material filling the gap to electrically shield the conductor bar end portion an applied filler material filling the gap to electrically shield the conductor bar end portion, wherein the filler material defines a greater than 0.080 to about 1.5 inch continuous outer radius surface end portion.

    Abstract: 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.

    Abstract: An end winding (10) of a high voltage air-cooled ac generator or motor is made more resistant to surface deterioration by corona activity by using a paint whose binder contains at least 20% by weight silicone. An end winding, including its insulated conductors and separator and support structures, are coated with the paint whose composition includes a solvent or thinner, optional pigments, and the binder containing at least 20% by weight silicone. The balance (if any) of the binder can be, for example, an alkyd, acrylic, phenolic or epoxy resin.
