摘要:
Method of making insulated conductor wire in which a homogeneous mixture of a dielectric carrier and magnetically permeable particles is sprayed onto the wire to deposit a layer of the mixture on the wire. The layer is then hardened to provide an insulating layer with the particles substantially uniformly dispersed therein.
