High-voltage power supply and distribution is the most common in the power supply and distribution system. The electrical equipment in the line has been exposed to the sun and rain for many years, and the aging and damage of the line often occur. It is the most commonly used method for power companies to overhaul electrical equipment. Commonly used tools for high-altitude operations include liftable arm trucks, insulating ladders, insulating platforms, etc. The bucket arm trucks are only suitable for flat areas; while the insulating ladders can only be used for low-altitude liveline work in good terrain. Moreover, its center of gravity is high, and it is prone to overturning; although the insulating platform is not restricted by the terrain, it needs to be fixed on the cement pole, which limits the range of activities of the operator, and requires multiple replacements or the use of multiple insulating platforms. Just increased work difficulty, also reduced work efficiency simultaneously.
