500千伏输电线路绝缘子在长期挂网运行中由于自身质量、外力破坏等原因，绝缘子断裂、烧伤缺陷时有发生，为保证输电线路安全稳定运行需对其带电及时更换。然而，由于山顶或大跨越铁塔垂直荷载较大的原因，常规带电作业工器具不能满足提升导线的要求，本文主要介绍新研制的导线提升专用装置，该装置能够提升大吨位导线，以达到更换复合绝缘子的目的。此装置对减少设备临时停电次数，缩短带电作业工作时间，提高工作效率具有重大意义。

The 500kV transmission line insulator hanging in the long run because of their quality problems or external damage, the insulator breakage and burns defects have occurred. In order to ensure safe and stable operation of transmission lines, the insulator need to be replaced in time with live working. However, in case of the Hilltop Tower or the Big leap tower, because of the large vertical load, conventional live working tools and instruments do not meet the requirements, this paper introduces the newly developed wire lifting device that can enhance the large tonnage wire to achieve the purpose of replacing insulators. This device has a great significance of reducing the number of temporary equipment, shortening live working time and improving work efficiency.
