背景技术Background technique

随着现代城市开发加速，35kV老旧输电线路线路的归并成为电力部门施工的新课题，需要解决以下问题：1、需要将两个双回线路归并为一个通道同杆四回架设；2、因线路需穿越其他高压线，因此杆塔高度不能太高，且要方便线路分支转角。现有结构的输电杆塔尚无法较好满足上述使用要求。With the acceleration of the development of modern cities, the merging of 35kV old transmission lines has become a new topic in the construction of the power sector, and the following problems need to be solved: 1. It is necessary to merge two double-circuit lines into one channel and erect four circuits on the same pole; 2. The line needs to cross other high-voltage lines, so the height of the tower should not be too high, and it should be convenient for the line to branch and corner. The transmission poles and towers of the existing structures still cannot satisfy the above-mentioned requirements for use well.
