摘要
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) 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.
