Dry type transformer winding
专利汇可以提供Dry type transformer winding专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a dry type transformer winding having superior humidity resistance and dust resistance against humidity and dust in air to come in contact with the winding by a method wherein the sheet of an insulator having high density and hard to transmit water, etc., is inserted between a conductor and an enclosing insulator. CONSTITUTION:The insulator sheet 5 of high density is wound around between the enclosing insulator 1 using a prepreg tape or a prepreg sheet, etc., and the winding conductor 2. A polyamide-imide film or a polyester film, etc., is used for the sheet 5 thereof, and the edge parts 5a are made as to be extended to the outer sides than both the edges of the winding conductor 2. Edge part insulators 3 to cover comparatively thick both the edge parts of the winding conductor 2 are formed of molding resin. Molding resin and the prepreg sheet 1 have favorable adhesion, and are adhered powerfully after hardening by heating. Humidity passed through the thin prepreg tape arranged inside of the outermost side of the coil is intercepted by the sheet 5 thereof.，下面是Dry type transformer winding专利的具体信息内容。
