架空光缆飞线技术研究

Study on the Flying Line of Aerial Optical Cable

光缆架空敷设方式的特点是建设速度快、投资少,广泛应用于本地网建设和部分干线建设中。为保证飞线安全,应使飞线跨越采用独立受力段设计,且应分别设立跨越杆与终端杆,其中跨越档应采用H杆并安装正辅吊线,终端杆应采用单杆。同时,给出了H杆及终端杆的拉线设置原则,为架空飞线的设计提出了较好的解决方法。

The aerial cable is characterized by its fast construction speed and low investment.It is widely used in local network construction and some trunk construction.In order to ensure the safety of flying line,the independent stress section design should be adopted to finish the flying line crossing.The crossing pole and the terminal pole should be set up separately,and the crossing span should be H pole and be installed main and auxiliary suspension wire,the terminal pole should use single pole.At the same time,the stay wire setting principle of H pole and terminal pole is given,and a good solution for the design of overhead flying line is put forward.
