摘　　要：积石峡水电站330kV送出工程的电站出线侧地形复杂、施工环境恶劣,该工程在架线施工中存在导线上扬、导线在放线滑车上的包络角过大、压接管或压接管保护钢甲通过滑车时超过允许荷载等问题。提出了相应的解决方案,实践证明该方案是可行的,可为山区架线施工工程提供参考。The terrain condition for the 330 kV power transmission project of Jishixia hydropower station is complex and the construction environment is bad.It is analyzed that this project has suffered from a series of problems such as conductor upward,big enveloping angle of conductors,and over load of the connecting pipe under pressure or its protecting steel armor when passing the pulley.On this basis,this paper proposed relevant solutions and schemes.The implemented construction proved the feasibility of the proposed scheme,which can provide reference for tension stringing projects in mountainous areas.
