Abstract

FIL METALLIQUE ISOLE PAR UNE MATIERE PLASTIQUE EXPANSEE COMPORTANT UNE COUCHE ISOLANTE DE MATIERE PLASTIQUE EXPANSEE FORMEE SUR UN CONDUCTEUR. LA MATIERE PLASTIQUE COMPREND AU MOINS UN CONSTITUANT AYANT UN RAPPORT DE GONFLEMENT SUPERIEUR A 55 QUI REPRESENTE AU MOINS 20 EN POIDS DE LA COUCHE ISOLANTE. LE FIL ISOLE EST FABRIQUE EN AJOUTANT UN AGENT D'EXPANSION TEL QU'UN AGENT D'EXPANSION CHIMIQUE OU UN GAZ INERTE, ET EN EXTRUDANT LE MELANGE SUR UN CONDUCTEUR. APPLICATION A LA REALISATION DE CABLES ELECTRIQUES.METAL WIRE INSULATED BY AN EXPANDED PLASTIC MATERIAL CONTAINING AN INSULATING LAYER OF EXPANDED PLASTIC MATERIAL FORMED ON A CONDUCTOR. THE PLASTIC MATERIAL INCLUDES AT LEAST ONE CONSTITUENT HAVING A SWELL RATIO GREATER THAN 55 WHICH REPRESENTS AT LEAST 20 BY WEIGHT OF THE INSULATING LAYER. THE INSULATED WIRE IS MADE BY ADDING AN EXPANSION AGENT SUCH AS A CHEMICAL EXPANSION AGENT OR INERT GAS, AND EXTRUDING THE MIXTURE ON A CONDUCTOR. APPLICATION TO THE REALIZATION OF ELECTRIC CABLES.
