Abstract

PURPOSE:To obtain the film suitable for high voltage by a method wherein an insulating layer consisting of a thermocuring prepreg mica tape is wound around a coil conductor, and a film release-treated with silicon resin and a film being composed of a soft polymer layer of urethane rubber containing the particles of carbon, etc. are wound on the insulating layer. CONSTITUTION:When manufacturing the coil 4 for the electric apparatus, the thermocuring prepreg mica tape using a fibrous base cloth or a film as a base material is wound around the coil conductor 5 and the insulating layer 6 is formed, and the corona preventive film 1 release-treated is further wound on the surface. In this constitution, the film 1 is formed by laminating the film 3 release-treated by means of the coating of silicon resin and the soft polymer layer 2 of urethane rubber, etc., which contains the semiconductor particles of carbon or silundum or the like and volume resistivity thereof is 10<2>-10<19>OMEGAcm. Accordingly, the coil, not only electric characteristics but also abrasion resistance thereof are large, can be obtained.
