Abstract:
An ultra-thin wall cable for automotive service comprising:a) a conductor nucleus consisting essentially of a smooth, annealed, geometrically formed joint of copper wires; and b) an insulating thermoplastic cover which is being formed of polyvinyl chloride (PVC) composition which is lead free, flame retardant, resistant to abrasion and gasoline and pinch test, said cable fabricated in three stages: i) stretching said copper wires by a one-row or multi-row drawing machine; ii) passing said wires through a single or double torsion joining machine; wherein steps (i) and (ii) are performed in such manner as to result in a geometrically constructed joint which is sufficiently smooth and having slight undulations without using an adhesive; iii) positioning the insulating thermoplastic cover concentrically around said conductor nucleus; and iv) extruding said cover around the conductor nucleus.
