Abstract

The invention relates to a process for continuously enamelling aluminium alloy wires in a raw state from wire drawing. This process consists in treating the wire surface by phosphoric anodizing in a solution of specified conductance in the presence of a surface-active agent before enamelling it. It finds its application in the manufacture of electrical windings such as especially motor and transformer windings.
