Title
(EN) AN APPARATUS FOR WRAPPING FIBRE OPTIC CABLE AROUND AND OVERHEAD LINE
(FR) APPAREIL SERVANT A ENROULER UN CABLE OPTIQUE AUTOUR D'UNE LIGNE AERIENNE
Abstract
(EN)
The present invention relates to an apparatus for wrapping fibre optic cable around an overhead line, comprising a carriage (1) which sits on the overhead line (A) and is moveable along the overhead line (A), a supply of fibre optic cable (B) located on one side of the carriage (1) and a counterbalance (3) for the cable supply located on the other side of the carriage (1). Gear means (4) are arranged to cause rotation of the carriage (1) around the overhead line (A) when the carriage (1) moves along the overhead line (A) thereby wrapping the fibre optic cable (B) around the overhead line (1). Tensioning means (5, 6, 7, 8, 9, 10, 11) are provided which apply a substantially constant tension to the fibre optic cable (B) during all modes of operation of the apparatus.

Cette invention concerne un appareil servant à enrouler un câble optique autour d'une ligne aérienne. L'appareil comprend un chariot (1) qui repose sur la ligne aérienne (A) et peut se déplacer sur cette dernière (A), une alimentation en câble optique (B) située sur un côté du chariot (1) et un contrepoids (3) associé à l'alimentation en câble optique situé de l'autre côté du chariot (1). Des dispositifs d'engrenage (4) sont disposés de manière à faire tourner le chariot (1) autour de la ligne aérienne (A) lorsque le chariot (1) se déplace sur cette dernière (A), afin d'enrouler ainsi le câble optique (B) autour de ladite ligne aérienne (1). Des dispositifs tendeurs (5, 6, 7, 8, 9, 10 ,11) sont prévus pour appliquer une tension sensiblement constante sur le câble optique (B) pendant tous les modes de fonctionnement de l'appareil.
