Abstract
Method of manufacturing electrical cables for underground lines and in particular cables of this type intended for the conduction of three-phase currents characterized by the following phases or operations: extrusion of the aluminum conductors that have to form the cable in such a way that each of these conductors have a circular sector with an arc of 120º so that the juxtaposition of these conductors forms a circle in transverse section surrounded by each of the conductors also by an extrusion process inside a coating of insulating plastic material; coupling of the three insulated conductors thus constituting the conductive core of the cable distortion of the group of three conductors according to a relatively long pitch propeller; in a given set of these three groups of helix conductors by several turns in a strip of a plastic material in laminates coating the conductive core thus insulated with a set of aluminum strips juxtaposed by their edges in direct contact with the joint insulation of the core coupling this cover of aluminum strips so that they describe a helical line with a shorter pitch than that of the conductors of the cable and in the opposite direction; and coating this core of insulated and reinforced conductors by means of an outer sheath made of a synthetic elastomer and this outer coating being carried out by means of the extrusion process.
