ABSTRACT OF THE DISCLOSURE The invention is an improved method for producing insulated winding wire by extruding a thermoplastic material onto the wire. The thermoplastic material is a partly crystalline thermoplastic polycondensate having crystal- lite melting point above 170°C, which is polyethylene terephthalate filled with between 5 and 15% by weight of titanium dioxide. Such insulated wire avoids the disadvantage that after winding and storage fine cracks appear in the coated surface.
