Ahmedabad is the largest city in Gujarat with a beautiful scenery and pleasant climate. January 14th of each year is the harvest festival in Gujarat and locals hold the festival before the harvest festival.
The Kits Festival on-site
On the Kite Festival, the sun starts moving northward marking the end of winter in India. Indians of all ages fly kites cheerfully from sunrise to sunset! However, after the festival, Indian electricians must face a serious challenge - cleaning up kites entangled in high-voltage lines.

As we all know, as long as there is a little foreign body hanging on the wire, once the wind, rain and lightning occur, it is easy to cause short circuit, and even trigger large-scale power failure, resulting in serious losses. What's more, after the festival, so many kites wrap around the high-voltage power line, so they need to be removed immediately. However, this is not an easy task for Indian electricians. Cleaning up suspended kites requires several electricians to board the tower together and work for six or seven hours to clean up, which is a time-consuming and dangerous work.

Not long ago, China's electricity workers faced the same problem. Every tree, kite, nylon bag, shading plastic net and tree obstacle is the natural enemy of overhead lines. For this reason, power grid has to carry out more than 200 times of obstacle removal every year, and it is very difficult to deal with it.
In the past, electric workers manually clean foreign bodies on high-voltage lines
With the tireless efforts of the research and development team, laser obstacle remover was developed. Now, with the help of laser obstacle remover, electricity workers can finish it in minutes by simply tapping the keyboard and locking the obstacle according to the high-definition display. This brings great convenience to the obstacle removal work, and the safety problems of electric workers have also been alleviated.

Early laser foreign body removal device - laser obstacle remover
After several product iterations, today's early laser foreign body removal devices (laser obstacle remover) have evolved from bulky behemoths to small objects that can be carried in just a small box, with greater power and wider range of applications.
SPT laser foreign body removal device (laser obstacle remover)
The new laser cannon operates at a distance of 5-300 meters and protects transmission lines from obstructions in all directions. It can remotely remove kites, balloons, agricultural film, plastic bags, hornets, bird's nest, tree obstacles and other non-metallic obstacles, and further improve the stability of transmission lines.

Moreover, lidar is used to collect data from power grid area with foreign bodies hung, and real-time images are processed to facilitate staff to observe the combustion or gasification degree of obstacle cleared by laser beam, reasonably grasp the laser irradiation time, and ensure that laser obstacle removal will not cause damage to transmission lines.
At present, laser foreign body removal device (laser obstacle remover) has been gradually applied to daily transmission line maintenance by power companies all over the country to remove laser foreign bodies, providing a reliable guarantee for the safe operation of transmission lines.
