The insulation coating robot can realize live insulation coating on 10kv/35kv/66kv bare wires.The robot and UAV work together to automatically go online. The operation of the coating robot is intelligent and simple, without the operation of the insulating aerial device and aerial workers. It is applicable to a variety of terrain ,especially in the environment where insulating aerial device cannot pass. Autonomous on-line is less restricted by the terrain and the double tank coating operation is highly efficient.
