摘要
在架空输电线路设计中,对OPGW的外径有着严格的限制,由此也限制了OPGW内的光纤最大容纤数。为满足未来智能电网对光纤通信的要求,试制了一种新型的外径为200μm光纤,代替目前常规的外径为245μm光纤,以达到增加OPGW内光纤芯数的目的。在结构相同情况下,采用200μm光纤可使光纤数量增加三分之一以上,试制的OPGW样品各项性能满足标准要求。
The external diameter of OPGW is strictly restricted in overhead transmission line design, which conse- quently restricts the maximum fiber-count of OPGW. To thlfill the requirements of thture smart grids tor optical fiber communication, we trial-produced a new type of optical fiber with 200 μm external diameterto replace the conventional 245μm diameter fiber, so as to increase the amount of fibers inside OPGW. With the same OPGW structure, using 200μm diameter fibers increased the amount of fibers inside OPGW by more than 1/3. The peribrmances of the trial- produced OPGW sample with new 200μm diameter fibers met the standard requirements.
