Abstract

DES CANNELURES SONT MENAGEES A LA PERIPHERIE DE LA COUCHE DISPOSEE SOUS L'ECRAN METALLIQUE ET CONSTITUEE PAR UNE SUBSTANCE ELASTIQUE, CANNELURES DANS LES CREUX DESQUELLES ON INTRODUIT UNE MATIERE D'ETANCHEITE DILATABLE EN PRESENCE D'EAU. SELON LA PRESENTE ADDITION, ON INTRODUIT EN OUTRE DANS CES CREUX UN MELANGE COMPRENANT DES ELEMENTS SEMI-CONDUCTEURS ET DES ELEMENTS PRESENTANT UNE RESISTANCE A VARIABILITE NON-LINEAIRE EN FONCTION DE L'INTENSITE DES COURANTS CAPACITIFS DE FUITE. APPLICATION : CABLE ELECTRIQUE A ACCESSOIRES D'ENCOMBREMENT REDUIT.
