光纤复合相线设计应用探讨

贵州地区35kV变电站将逐步实现光纤通信网络覆盖，但在贵州山区对于本身无地线的中低电压等级输电线路需架设光纤时，当不宜采用ADSS光缆或加强杆塔、基础有难度时，光纤复合相线（OPPC）可以作为光纤通信的一种补充解决方案。通过对一个具体35kV工程的光纤设计选型过程，比较了几种光缆的优缺点，并阐述了光纤复合架空相线的设计要点，对贵州山区采用OPPC线路的一般选择原则进行了总结。

The design and application of the optical fiber composite phase line

The optical communication grid will gradually. However, when putting optical fiber cover the 35kV transformer substation in Guizhou district in the medium low voltage level power line in Guizhou district and when it is inappropriate to use ADSS optical fiber or the reinforce of the pole and the foundation is difficult, the optical fiber composite phase line （OPPC）can be served as a complement solution proposal. The paper compares the advantages and disadvantages of the various optical fibers through an optical fiber design and model selection process of the 35kV project. Besides, the paper presents the design key point of the optical fiber composite phase line and summarizes the common option norm of the OPPC circuit adopted in the Guizhou mountain area.
