摘　　要：针对超特高压输电线路发生的接续管破损、新建重要交跨物上方线路存在接续管及接续管口导、地线损伤等问题,介绍了1种新型预绞式接续条在接续管补强及导、地线断股修补上的应用情况。新型预绞式接续条的接续电阻、温升及握力等性能指标均符合有关标准的要求,可完全恢复线路机械强度,大大改善接续长度内导线的导电性能。To splice bars damaging, splice bars above the new-building important cross objects and wire damaging near the splice bars occured on EHV／UHV transmission lines, introduced a new type of pre-twisted splice bar used in the tube reinforcement and wire mending. The connection resistance of pre-twisting splice, temperature rise and grip strength performance all met the requirements of relevant standards, could fully restore the line mechanical strength, and greatly improve the conductivity within the length of connection section.
