<p>Method of continuously manufacturing a coaxial cable the dielectric of which consists at least partly of a gas, such as air, in which cable spacers are provided on a wire of a conductive material which serves as the central conductor, after which the spacers are surrounded by and envelope which comprises a cylindrical outer conductor and an outer sheath made of a synthetic material, characterized in that a cylinder of synthetic material is continuously provided by extrusion so as to concentrically surround a wire made of a conductive material; after cooling of the synthetic material, parts of the cylinder are mechanically removed at intervals and evenly distributed along the length of the cylinder, which parts are separated by parts of the cylinder bounded by the peripheral surface of the sheathing, gas-filled spaces, which extend in the direction of length of the cable and do not communicate with one another, are produced between the cylinder parts left around the central conductor and surface of the sheathing which faces the cylinder.</p> |
