摘　　要：特高压输电线路架空导线截面不断增大、分裂数不断增加,给导线架设带来新的技术难题。通过对1 250 mm2级大截面导线架设技术、工器具选型、放线滑车悬挂、放线、紧线等施工工艺的研究,在昌吉-古泉±1 100 k V特高压直流输电工程6B标段中得到成功应用,解决了大截面多分裂导线架设技术难题,为今后特高压线路工程八分裂1 250 mm2级大截面导线架设提供参考和指导。The section of overhead conductor of UHV transmission line is increasing and the number of splitting increases continuously, which brings new technical problems to the erection of the conductor. Through the research on the construction technology of 1 250 mm^2 large cross -section lead wire, the selection of tooling, the suspension of trolley, the pay - off line and the tight line, etc. , in the section 6B of Changji-Kuquan ± 1 100 kV UHVDC Transmission Project It has been successfully applied to solve the technical problems of erecting large cross-section multi-split wires and providing reference and guidance for the follow-up erection of 1 250 mm^2 large cross-section wires in eight-split UHV transmission line project.
