摘要： Process for manufacturing a cable comprising the following steps:(a) conveying at least one conductor to an extruder apparatus;(b) extruding an insulating coating layer radially external to said at least one conductor; (c) longitudinally folding a metal tape around said extruded insulating coating layer, said metal tape bearing at least one adhesive coating layer in a radially external position; (e) extruding at least one continuous coating layer comprising at least one polyamide or a copolymer thereof around and in contact with said folded metal tape; wherein the step (e) is carried out at a draw down ratio (DDR) not higher than 2.5, preferably of from 1.2 to 2.0.
