ABSTRACT:
An enameled wire having resistance to overload which comprises an electric conductor and a baked wire enamel coat is disclosed. The wire enamel coat is applied to the conductor through a die from wire enamel comprising a silicone resin having incorporated therein 50 to 200 phr of particles of an inorganic tabular crystalline material that have a maximum average particle size not greater than 80.mu., an average not greater than 40.mu. and an average aspect ratio between 30 and 100 and which react with the silicone resin at elevated temperatures to become a ceramic and which have been surface-treated with a coupling agent, a surface active agent or a coating agent. The tabular crystals in the wire enamel coat are orientated parallel to the surface of the conductor. The enamel coat has good adhesion to the conductor and will not easily crack or peel off the conductor even when subjected to high temperatures and adverse physical stress.
