The paper puts forward concrete methods and technical standards suitable for protective measures of site constructions of communication optical cable line overhead project as good reference to the similar project constructions. 本文针对通信光缆线路架空工程施工中应采取的防护措施,提出了适合现场施工的具体方法和工艺标准,对同类工程施工具有较好的参考意义。
In electrical power system, most of the breakdowns occur on transmission line ( especially overhead line ). 在电力系统的故障中,大部分的故障出于输电线路(尤其是架空线路)。
This thesis calculates the best installed position of a coupling line in 10 kV overhead lines when the lines are arrayed in triangle or in one line. 同时对10kV架空线路中导线三角形排列和垂直排列两种情况下,对耦合导线的最佳安装位置进行了计算。
