Title (EN) METHOD FOR THE PRODUCTION OF AN ELECTRICAL CABLE BY EXTRUSION OF A COMPOSITION COMPRISING A PROPYLENE POLYMER AND A DIELECTRIC LIQUID
(FR) PROCÉDÉ DE FABRICATION D'UN CÂBLE ÉLECTRIQUE PAR EXTRUSION D'UNE COMPOSITION À BASE D'UN POLYMÈRE DE PROPRYLÈNE ET D'UN LIQUIDE DIÉLECTRIQUE
Abstract:
(EN) The invention relates to a method for the production of an electrical cable comprising an extruded thermoplastic layer obtained from a composition comprising at least one dielectric liquid and at least one thermoplastic polymer selected from a homopolymer and a copolymer of propylene, as well as to a cable produced using said method.
(FR) L'invention concerne un procédé de fabrication d'un câble électrique comprenant une couche thermoplastique extrudée obtenue à partir d'une composition comprenant au moins un liquide diélectrique et au moins un polymère thermoplastique choisi parmi un homopolymère et un copolymère de propylène, ainsi qu'un câble obtenu par ledit procédé.
