On July 2, in the power channel of the 110 kV high-duty line, there was a large horse cellar under an empty line cross-arm. The transmission personnel of Wuxi Power Supply Company cleared it with a “laser gun”. This is the first time that the laser clearing technology has been applied to the power supply line in the Wuxi power grid.
It is reported that this kind of equipment is a remote re-wiping device for foreign objects in the grid, which consists of a laser launching gun, an operating platform and a manipulator. After the power transmitter aimed the laser gun at the horse cell, the button that emits the laser was pressed. In just two seconds, the horse honeycomb started to smoke. Within 10 seconds, the horse cells have all burned out.
The "laser gun" used on the power channel line has an effective range of 120 meters, which can protect the power line from the intrusion of floating objects and improve the reliability of power supply. With the "laser gun" device, the clearing work can also be completed under live conditions, reducing customer power outage time.
