Abstract

L'invention concerne un faisceau (9) de câbles équipé d'un élément (24) de logement, d'un trajet conducteur (25) à haute tension inséré dans ledit élément (24) de logement, et une pluralité d'éléments (20) de fixation servant à fixer le faisceau (9) de câbles dans une position prescrite. L'élément (24) de logement est formé sous la forme d'un tube destiné à l'insertion et à la protection du trajet conducteur (25) à haute tension. L'élément (24) de logement est un article moulé en résine, et des sections minces (38-40) sont formées sur le côté intérieur de l'élément de logement. Les sections minces (38-40) sont formées de façon à être disposées en fonction de zones où l'écart entre des éléments (20) de fixation adjacents est étroit. Les sections minces (38-40) sont formées en tant que zones de réduction de poids.
