摘　　要：按照SDJ 226—87《架空送电线路导线及避雷线液压施工工艺规程》对1 000 mm2大截面导线进行压接施工时,容易在管口附近出现比较严重的散股现象。通过对1 000 mm2大截面导线特点分析,并结合试验结果,提出了几项有效、可行的减少液压压接散股程度的措施,对提高大截面导线的施工质量具有积极的作用。According to SDJ 226-87 ＂Code for Hydraulic Construction Technology of Overhead Transmission Lines and Grounding Wire＂,when the 1 000 mm^2 cross-section conductor is jointed by compression,the phenomenon of loose strands frequently occurs around the tube end.Based on an analysis of the characteristics of 1 000 mm^2 cross-section conductors and the testing results,some effective measures are proposed to reduce loose strands for hydraulic jointing,which will be very helpful for improving the construction quality of large cross-section conductors.
