Abstract
A method for producing electrically insulated apparatus, which may be used in windings for rotary electric machines, for example, an induction motor, synchronous machines, DC machines or stationary induction apparatus, for example, transformers, and the product produced thereby comprising an electric conductor and an insulating layer formed around the electric conductor, wherein said insulating layer contains a resin having excellent permeability for the gas generated in the layer, e.g., a silicone resin, and a resin having excellent adhesive force in an appropriate blending ratio in order to impart excellent thermal resistance to the electrically insulated apparatus.
