Method of manufacturing a polymer-insulated conductor

摘要

The present invention relates to a method of manufacturing a polymer-insulated conductor. The method comprises the steps of a) providing a conductor having a first cross-sectional shape, b) passing the conductor through a conductor-shaping die to shape the conductor such that the conductor obtains a second cross-sectional shape, wherein heat is developed in the conductor, c) applying molten polymer to the conductor when the conductor is in a heated state resulting from step b) to obtain a polymer-coated conductor, and d) shaping the polymer-coated conductor by means of a polymer-shaping die to thereby obtain the polymer-insulated conductor.
