Abstract

a. Câble à haute immunité à blindage mince. b. Câble caractérisé en ce que le blindage est formé par au moins trois couches dont deux sont conductrices et alternent avec une couche à haute perméabilité, la résistance de chaque couche conductrice étant égale au plus à cinq fois celle d'un tube continu, en cuivre de même épaisseur, et de même rayon moyen.
