Abstract

CONDUCTEUR ELECTRIQUE AYANT UNE CHARGE INDUCTIVE CONTINUE ET PROCEDE DE FABRICATION D'UN TEL CONDUCTEUR. UN CONDUCTEUR ELECTRIQUE, PARTICULIEREMENT APPLICABLE AUX CABLES POUR TELECOMMUNICATIONS, COMPREND UN CONDUCTEUR METALLIQUE AVEC UNE COUCHE DE MATERIAU COMPOSITE MAGNETIQUE-DIELECTRIQUE, DE FACON A DONNER UNE CHARGE INDUCTIVE CONTINUE. LE MATERIAU MAGNETIQUE PEUT ETRE CONSTITUE DE MATERIAUX FINEMENT DIVISES ET LE MATERIAU DIELECTRIQUE D'UNE VARIETE DE MATERIAUX. UN CABLE DE TELECOMMUNICATIONS SERA CONSTITUE D'UNE PLURALITE DE PAIRES DE CONDUCTEURS, CHAQUE CONDUCTEUR AYANT UNE AME METALLIQUE ET COMPORTANT LA COUCHE DE MATERIAU COMPOSITE. UNE COUCHE ISOLANTE EST GENERALEMENT FORMEE SUR LA COUCHE COMPOSITE. LA COUCHE COMPOSITE PEUT ETRE FORMEE, PAR EXEMPLE, PAR EXTRUSION OU PAR REVETEMENT ELECTROSTATIQUE. APPLICATION A LA FABRICATION DES CABLES POUR TELECOMMUNICATIONS.ELECTRIC CONDUCTOR HAVING A CONTINUOUS INDUCTIVE CHARGE AND METHOD FOR MANUFACTURING SUCH A CONDUCTOR. AN ELECTRICAL CONDUCTOR, ESPECIALLY APPLICABLE TO TELECOMMUNICATION CABLES, INCLUDES A METAL CONDUCTOR WITH A LAYER OF MAGNETIC-DIELECTRIC COMPOSITE MATERIAL, SO AS TO GIVE A CONTINUOUS INDUCTIVE LOAD. MAGNETIC MATERIAL MAY CONSIST OF FINALLY DIVIDED MATERIALS AND DIELECTRIC MATERIAL OF A VARIETY OF MATERIALS. A TELECOMMUNICATIONS CABLE SHALL BE CONSTITUTED OF A PLURALITY OF PAIRS OF CONDUCTORS, EACH CONDUCTOR HAVING A METAL CORE AND INCLUDING THE COMPOSITE MATERIAL LAYER. AN INSULATION LAYER IS GENERALLY FORMED ON THE COMPOSITE LAYER. THE COMPOSITE LAYER CAN BE SHAPED, FOR EXAMPLE, BY EXTRUSION OR BY ELECTROSTATIC COATING. APPLICATION TO THE MANUFACTURE OF TELECOMMUNICATION CABLES.
