Abstract
A multilayer insulated wire has a conductor and solderable extrusion-insulating layer made up of two or more layers for covering the conductor. At least one insulating layer including the outermost layer is formed by a mixture of 100 parts by weight of resin components in which 100 parts by weight of a thermoplastic polyester-series resin (A) is blended with 5 to 40 parts by weight of an ethylene-series copolymer having a carboxylic acid component or a metal salt of the carboxylic acid component in its side chain, and 10 to 80 parts by weight of an inorganic filler (B). A transformer which utilizes the multilayer insulated wire has excellent solderability, high-frequency characteristics, peel resistance under high-voltage and high-frequency, and coilability, and it is favorably suitable for industrial production. A transformer utilizing the multilayer insulated wire has excellent electrical properties and high reliability, because when used at high frequencies, there arises no problem of lowering of electric properties and scraping-off from the wire by corona.
