Abstract: In recent years, with the rapid development of the social economy and the increasing demand for power supply reliability from users, 10 kV live working has become an important means for power grid enterprises to optimize services and reduce power outages. In the early days, the use of insulated bucket trucks had limitations such as poor terrain adaptability and high cost. This subsequently evolved into the insulating ladder platform method, which relies on high dielectric strength devices to facilitate intermediate potential working. However, the existing insulation ladder is bulky and time-consuming due to its built-in climbing ladder, and the flexible fixation of the cable wind rope causes operational shaking, posing safety hazards. To address these issues, this paper proposes optimizing the structural design and fixation method of the insulating ladder to enhance its installation convenience, stability, and safety. Field applications demonstrate that the setup efficiency of the proposed insulating ladder in complex terrains is increased by 60%, and its operational stability is improved by 40%, providing an efficient and safe solution for 10 kV live working.
