China Electric Power Bureau’s Laser Cannon

In online games, you may have seen a laser cannon to hit the aircraft. Have you ever heard of using a laser cannon to remove foreign matter on high voltage lines?

It is understood that overhead line foreign body hanging line is one of the main causes of unplanned outages. The current methods of scavenging mainly include unmanned aerial vehicle (UAV), flame cleaning, insulated bucket vehicles, lift off and so on. But the above technology or the clearing instrument is close to the live line, there is safety risk, or the operation time is long, the labor intensity is high, and the labor risk is great.

In order to ensure the UHV line on time and safely put into operation. State Grid Jiangsu power will use laser cannon technology to remove foreign objects suspended on UHV lines and conduct line inspections. It is reported that the laser cannon is called “laser rapid clearing instrument”. It is a self-developed foreign body cleaning equipment for the first transmission line at home and abroad by Jiangsu electric power company of state grid. The device can irradiate the laser beam with proper energy to the foreign body of the transmission line at a long distance. Under the condition of ensuring safety, the device will burn the part that is wound on the wire and cause the foreign object to fall.
