Method and apparatus for pre-heating the conductor elements of cables with extruded insulators, in particular conductors with metal tape reinforcements

摘要

The method and the apparatus of the invention use preheating 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 conductors elements.
