Anode, fremgangsmÕte for eloksering, eloksert vaier og elektrisk anordning med slik eloksert vaier

摘要

An anode, process for anodizing, an anodized wire and electric device having an anodized wire for use in high-voltage electric machines. A predetermined length of metallic conductor wire is wound around a holder, where respective windings are separated from one another with guide cams and guide slots. The metallic conductor wire and holder are then disposed in an electrolyte, where both ends of the metallic conductor wire are connected to a positive pole on a current source so as to implement the anodization operation. An oxide layer is formed as a result of the anodizing operation on a metallic portion of the metallic conductor wire. Properties of the oxide layer are such that the electrical insulation properties and adherence of the oxide layer to the wire are suitable for use in windings of electric machines for high-voltage applications.
