For this reason, live construction work has been carried out to reduce the scope and duration of power outages and ensure that users' demand for power can be met.

At present, the live construction tools that can quickly reach the accident site are mainly 10kV insulated arm trucks. However, due to the uncertainty of the accident location, sometimes the 10kV insulated arm truck cannot reach the live work site. Even if it can reach the working place of live work, it often blocks traffic and causes adverse social repercussions. At the same time, the 10kV insulated arm truck is expensive, and the number of equipment is limited, so it cannot be used for a long time.

In addition, when carrying out live work on poles, due to the presence of many cross-posts and lead wires on the 10-110kV power lines on the nail poles, cable boarding poles and poles, the central wire of the 10-110kV power line has live defects. In the case of handling and repairing, etc., it is impossible to install the live working platform, which affects the development of live working. On the other hand, when crossing live 10-110kV power lines, it is not only dangerous to build wire-crossing racks with moso bamboo, but also has a large workload and is not insulated.
