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.
