This paper describes the manipulator for live-line construction of high-voltage overhead power distribution lines (line voltage: 6.6 kV) that is being jointly developed by Tokyo Electric Power and other companies. It describes the system's development concept and makeup as well as operability tests using actually installed distribution lines.In this research, development began in 1984. As the first step, a prototype model of a ground-mounted twin-arm manipulator was trial-manufactured in 1985.As the second step, in 1988 a vehicle-mounted system was developed in which the twin-arm manipulator was mounted on a telescopic aerial vehicle. As the third step, a practical system was developed based on these results.On-boom operation type systems are now stationed at two branch offices, and a ground operation type system at one branch office, to continue system improvement.In the development of this system, the task of development of the individual items of equipment was shared as follows.Project leader, conceptual design, and utility evaluation: Development of manipulator system (on-boom operation type):
