Process for manufacturing a cable resistant to external chemical agents

A cable comprising:

• at least one conductor;
• at least one insulating coating layer around said at least one conductor;
• at least one metal tape longitudinally folded around said at least one insulating coating layer, said metal tape bearing on its externally facing surface at least one ethylene based adhesive coating layer, wherein the longitudinally folded metal tape has a thickness of 0.05 mm to 1.0 mm and overlapping edges;
• at least one continuous coating layer comprising at least one polyamide or a copolymer thereof in a radially external position with respect to said at least one adhesive coating layer, said continuous coating layer being in contact with said at least one adhesive coating layer;
• at least one further adhesive coating layer in a radially inner position with respect to said at least one metal tape, said at least one further adhesive coating layer being in contact with said at least one metal tape;
• and
• at least one coating layer made of expanded polymeric material in a radially inner position with respect to said at least one metal tape.
