With rapid development of the global economy, electricity has become an indispensable energy resource. High-voltage power lines transmit steady streams of electrical energy to every corner of the world. The safe maintenance of these high-voltage power lines has become a top priority. Kites, cloth strips, balloons, and plastic bags often become entangled with the power lines, and if this is not handled in a timely manner, it is likely to cause trip events, resulting in a power outages. The removal of foreign objects caught on power lines has always presented a challenge in the maintenance of electric power grids.  Standard methods of foreign object removal for power lines include manual removal by ascending the towers, unmanned aerial vehicles, and manual removal with insulated aerial platforms. Such methods have following disadvantages: long working hours, high costs of human and material resources, low efficiency, and significant safety risks.
The Lasermach  Power grid foreign object cleaning instrument  overcomes the shortcomings of standard removal methods and solves the challenges of power grid maintenance and safety. The product emits an infrared laser from the ground at a specific power and a wavelength of 1064 or 532nm. When the facilities is powered on, foreign objects entangled on high-voltage lines are loosened and fall off, thereby allowing fast and safe removal. The removal process does not require the power lines to be switched off, and there is no need to manually climb up the towers. It can be safely applied in windy, rainy and nighttime conditions to remove kites, cloth strips, balloons, plastic bags, tree branches and other non-metallic foreign objects.
