Abstract
A sheathed control cable includes an inner cable, a cable-guide duct of a material having a low coefficient of friction surrounding said cable with clearance, armoring surrounding the cable-guide duct, and an outer sheath providing mechanical protection, wherein the cable-guide duct is a duct of microporous PTFE obtained by lubricated extrusion and that has been subjected, on leaving the extruder die, to simultaneous drawing and heating to a temperature above the sintering temperature of PTFE.
