OPGW光缆在我国电力通信领域普遍使用并在主干网络上的使用越来越普及,但是110 kV及以下的电网输电线路没有架设架空地线,所以无法实施OPGW光缆的安装。110 kV及以下电网在我国地、县级市所属的城网、农网中普遍使用,在现有的模式下只能考虑安装ADSS光缆,但是ADSS光缆的架设存在一定的限制,如遇电腐蚀毁缆、断纤及容易遭外力破坏,为了保证通信的安全性,可以考虑采用新型的电力特种光缆OPPC光缆。
OPGW fiber optic cable is widely used in China’s power communication field and has become more and more popular in trunk networks. However, the overhead power lines of 110 kV and below power grids are not erected. Therefore, the installation of OPGW optical fiber cables can not be implemented. The 110 kV and below grids are commonly used in urban and rural areas in China and county-level cities. Only ADSS cables can be considered in the current mode. However, the installation of ADSS cables has some limitations, such as electrical corrosion Destroyed cable, broken fiber and easily damaged by external forces, in order to ensure the safety of communications, you can consider the use of a new type of power OPPC cable optical cable.
