Abstract

L'invention concerne un câble de communication comprenant une pluralité de paires torsadées, une couche de torsion des conducteurs enveloppant les paires torsadées et une gaine enveloppant la couche de torsion des conducteurs, chaque paire torsadée étant constituée de deux conducteurs centraux en cuivre isolés et d'une bande de composé aluminium-plastique, la bande de composé aluminium-plastique enveloppant les conducteurs centraux en cuivre isolés, et la surface conductrice de la bande de composé aluminium-plastique se situant à l'extérieur, et un conducteur en cuivre pour mise à la terre à l'intérieur de la couche de torsion des conducteurs mais à l'extérieur des paires torsadées. L'invention concerne également un procédé de traitement, un appareil de communication et un système pour le câble de communication. Comme le diamètre externe du conducteur dans le câble de communication est faible, il est malléable et facile à disposer, et permet de réduire les coûts.
