Abstract
In order to provide windings for electrical rotating machines having an insulating film superior in electrical characteristics, a high heat conductive insulating film 11 is formed at outer periphery of wound conductor 10 using a high heat conductive insulating tape, which includes a mica layer 3, a reinforcement layer 5, and a high heat conductive filler layer 7, wherein the resin content in each layer of the mica layer 3 and the high heat conductive filler layer 7 is specified in the range of 10-25% by weight based on the whole weight of the material. 1-80% by weight of said filler is spherical.
