OPGW fiber optic cable has the dual functions of ground wire and communication fiber optic cable. It is install at the top of the power overhead pole tower. Compared with the ADSS fiber optic cable, it does not need to consider the best hang site, electromagnetic corrosion, man-made damage and other unfavorable factors,from the early 80s, OPGW fiber optic cables were widely used around the world for their high reliability, superior mechanical and electrical properties, and good performance and practicality. According to relevant domestic and foreign standards and their own installation experience, Let’s communicate togerther for the OPGW optical fiber cable installation and line tighted.
1. In principle, to install OPGW optical fiber cable must be blackout, can not be do the work in bad weather, thunderstorms and other adverse weather; must implement the “electrical safety work regulations”, fill the safety worksheet, implement the high-pressure overhead line safety work organization measures, Observe the relevant working procedures of the power system.
2. The deployment of OPGW cable should be carried out with tension to prevent the OPGW cable from directly rubbing against sharp sand and other ground. When laying, there should be someone with the line to observe the operation of the cable end anti-twist whip through the pulley. In particular, traffic crossings, communication lines, power lines, etc., must be monitored by special persons.
3. During the Installation of OPGW cable, there should not be any sudden vibration, pull or wire jump; ensure that the minimum bending radius of the optical cable is more than 500mm and must not be squeezed and twisted; the tension of the pay line is generally controlled below 1 ton. Not more than RTS 15~20 KN load.
4. The waterproof treatment is very important for the OPGW cable. After the opening test, the waterproof cap shall be restored until it is set up. In the erection process, all installers must correctly operate and use the installation tools and take appropriate personal protective measures to carry out operations. Otherwise, it may cause damage to construction workers and OPGW cables.
5. Before install the OPGW cable need Seriously check the start and end of the tower marked on the reel, after the length is correct.
