Electromagnetic insulation wire, and method and apparatus for manufacturing the same

摘要

The present invention is concerned with an electromagnetic insulation wire, a method of manufacturing the same and an apparatus for manufacturing the same. The wire comprises a conductor and an electromagnetic insulation coat containing magnetic powder dispersed in a resin matrix. The particles of the powder are oriented in the coat in the circumferential direction of the conductor. The particles are oriented in the magnetic field, while the conductor and the composite material are passed through a die heated to a certain temperature.
