摘要

目前,CVG EDELCA正在进行超过1360公里的传统地线更换项目,安装OPGW电缆以及在765千伏,400千伏和230千伏等高压水平下运行的初级和区域输电系统。理想情况下,执行这类项目需要将线路中断作为基本规则或预防措施。然而,在大多数情况下,破坏电力是不可能的;由于这个原因,它迫使我们在电力线运行时执行串接过程。CVG EDELCA正在用OPGW替换1360公里的传统地线,这使我们能够了解在带电线路上安装OPGW电缆的不同方法。本文介绍了在吊装方法和安全措施方面所取得的经验和细节,以及所使用的设备和其他相关方面

Methods for "Live Line" OPGW Cables Stringing at Voltage Levels of 400 kV and 765kV
Presently, CVG EDELCA is carrying out a replacement project of more than 1360 km of conventional ground wires, installing OPGW cables along with the primary and regional transmission systems operating at high voltage levels such as 765 kV, 400 kV, and 230 kV. Ideally, executing this kind of project requires the outage of the lines as a fundamental rule or precaution. However, is not possible to, in most cases, disrupt power; for that reason it forces us to execute the stringing process with the power lines in operation. CVG EDELCA is carrying out the replacement of 1360 km of conventional ground wires with OPGW which has allowed us to get to know different methodologies for OPGW cable installation on live lines. In this paper, the acquired experiences and details about stringing methods and safety measures are presented, as well as the used equipment used and other related aspects
