摘　　要：本文介绍了一种采用杆塔两端不锚固导地线方法,在空中杆塔上做记印,使导地线松落至地面上之后在导地线印记外侧,固定并收紧后开断导地线,压接导地线耐张线夹。该方法解决一个传统复杂的紧挂线操作程序,实现了利用小抱杆(或利用杆塔现有固定点)将输电线路直线开断改耐张的作业方法,解决传统输电线改造受到客观环境影响(如线长点多人员分散、通道难)和锚线、抽线施工周期长等线路改造中的种种困难。This article describes the tower without anchoring both ends of the ground guide ways,and then mark it on the tower, so that the ground lead to the ground after loosening, mark the outside of the ground in the guide, the guide is fixed and tightened breaking ground, pressed clamp on cables connected. The traditional way to solve a complex operating procedures hang tight, realized using small pole（or use an existing tower fixed point） to the linear transmission line method for breaking job-resistant sheets changed, the objective being to solve the transformation of the traditional environmental impact of power lines（eg length o’clock officers dispersed, Channel hard） and anchor lines, pumping long lines and other lines of construction period of transformation difficulties.
