Abstract

Câble haute tension à éléments de transmission optiques (1) intégrés à l'intérieur d'au moins une nappe d'éléments de câblage (5) résistant à la traction et d'au moins une nappe d'éléments de câblage (6) électroconducteurs. Les éléments optiques de transmission (1) peuvent être groupés pour former un faisceau de guide d'ondes lumineuses. Pour protégér les guides d'ondes lumineuses contre les détériorations mécaniques et les températures excessives en cas de court-circuit, ceux-ci sont entourés d'un élément tubulaire intérieur (2) en matériau moulé par injection, mécaniquement et thermiquement résistant. Ledit élément tubulaire intérieur est entouré par un élément tubulaire extérieur (3) en polyester à poids moléculaire extrêmement élevé, qui protège l'élément tubulaire intérieur du contact avec des agents provoquant des fissures par contrainte, comme par exemple l'eau de pluie, le rayonnement UV et les solvants.
