Abstract

Le but de la présente invention n'est pas seulement de blinder efficacement contre des ondes de bruit électromagnétiques générées par des câbles d'alimentation mais aussi d'empêcher un courant induit excessif de circuler dans des éléments de blindage. Ce faisceau électrique se compose de : trois câbles d'alimentation pour conduire une électricité à courant alternatif triphasé symétrique ; trois premiers éléments de blindage conducteurs qui entourent individuellement les trois câbles d'alimentation ; et un second élément de blindage qui entoure les trois premiers éléments de blindage ensemble tout en étant en contact avec les trois premiers éléments de blindage. Le second élément de blindage est plus grossier que les premiers éléments de blindage (1).
