A process for manufacturing an electric cable. In particular, the process
includes the steps of: a) feeding a conductor at a predetermined feeding
speed; b) extruding a thermoplastic insulating layer in a position
radially external to the conductor; c) cooling the extruded insulating
layer; and d) forming a circumferentially closed metal shield around the
extruded insulating layer. The process may be carried out continuously,
i.e., the time occurring between the end of the cooling step and the
beginning of the shield forming step is inversely proportional to the
feeding speed of the conductor.
