Abstract: An insulated electric conductor with increased adhesion of an insulating coating includes an electric conductor, preferably made of copper or aluminum, with an insulating coating having either at least one insulating layer made of thermoplastic material, or the insulating layer and a plastic-containing intermediate layer, obtainable by a method in which the electric conductor is placed under a protective gas atmosphere and is bombarded with ions of the protective gas in a gas plasma in order to remove an oxide layer formed on a surface of the electric conductor and/or to increase the surface energy of the electric conductor, and subsequently either the at least one insulating layer or, in the case that the coating includes the plastic-containing intermediate layer, at least the plastic-containing intermediate layer is applied directly to the surface of the electric conductor under a protective gas atmosphere.

Abstract: An insulated electric conductor includes a flat or round wire made of one or more electrically conductive materials, the flat or round wire having an exterior surface that is free of an oxide layer; and an insulating layer adhering directly to the oxide-layer-free exterior surface to form a coating around the oxide-layer-free exterior surface, the insulating layer being made of at least one thermoplastic material which provides electrical insulation. The flat or round wire is designed to conduct an electrical current.
