METHOD AND APPARATUS FOR PRE-HEATING THE CONDUCTOR ELEMENTS OF CABLES WITH EXTRUDED INSULATOR, IN PARTICULAR CONDUCTORS WITH METAL TAPE REINFORCEMENT

摘要

A method and apparatus for preheating the conductor elements of cables with extruded insulator essentially by forced thermal convection. Particularly for conductors with metal tape reinforcement, such as for example Milliken conductors, where it has been found that the traditional magnetic-induction heating is not satisfactory since the tape reinforcement shields the elements of conductors.
