Abstract

La présente invention concerne des câbles blindés qui possèdent une pluralité de fils (10) disposés à l'intérieur d'un tube (20) présentant des propriétés de blindage. Les câbles blindés sont caractérisés en ce que la pluralité de fils (10) sont séparés les uns des autres, et des attaches (30), qui maintiennent les fils (10) dans un état dans lequel la périphérie intérieure du tuyau (20) et les périphéries extérieures des fils (10) se touchent, sont disposées sur le tube (20). Les câbles blindés permettent d'améliorer la dissipation de chaleur tout en minimisant le bruit d'induction.
