May cause corrosion. Conventionally, in order to prevent this, a sheet having an adhesive rubber attached to the inner surface is manually wound around a damaged portion of the electric wire. However, this manual method is unstable and dangerous work at a high place, and requires skill and much labor. In addition, since work cannot be done without turning off the power, many inconveniences will be given to consumers during the power outage work.
For this reason, it has recently been socially required to carry out electrical work without power failure. However, it is not easy to work like a human hand with a remote control tool or manipulator (working robot) that enables live work.
