国外自70年代后期开始研究和使用光纤复合架空地线(OPGW)。OPGW线路的架设有一套专门的技术。我国自85年开始研制OPGW,首条全国产化OPGW线路已于89年元月开通并使用至今。本文着重对其施工技术作些陈述,并就架设过程中OPGW结构伸长和由此引起的光纤受力情况略作探讨。
Foreign since the late 70s began to study and use optical fiber composite overhead ground wire (OPGW). OPGW line erected a set of specialized technologies. Since the beginning of the development of OPGW in China in 1985, the first nationalized OPGW line was opened and used in January 1989. This article focuses on its construction technology to make some statements, and in the erection of the structure of the OPGW structure elongation and the resulting fiber stress a little discussion.
