Abstract
La présente invention concerne un câble électrique comportant un conducteur central torsadé (12) entouré d'un isolant (10) constitué d'un matériau qui confère au câble (11) des propriétés d'auto-obturation, situé au moins entre les bords adjacents du conducteur torsadé (12) et l'isolant (10). De préférence, ce matériau est un matériau polymère fluide à une température d'au moins 25 DEG C à peine et présente une valeur de pénétration d'aiguille de 100 grammes supérieure à 100 dixièmes d'un millimètre à 25 DEG C.
