Kite Laser Pointer Wrapped Around A Power Line
On the morning of the 18th, a laser pointer shot into the air. A kite wrapped around the high-voltage line near Huateng Road in Qingpu District slowly dropped. The device that emits the laser is similar to a camera, with a scientific name of laser obstruction remover, commonly known as "laser cannon". This is the latest "artifact" that operation and maintenance personnel of the State Grid Shanghai Electric Power Company's maintenance company have added to clean up obstacles such as kites, balloons, etc. that are wrapped around power lines. Add this laser pointer device at the same time. The unit has also specially formed a "sharp sword" clearance team.

Many people do not know that the cheapest red laser pointer on the market does not have an IR (infrared) filter. This means that it is inherently more dangerous because it emits invisible infrared light, which can be harmful if exposed for a long time. Ensure that all lasers under consideration, whether high-power or low-power, contain an infrared filter to obtain the safest beam.
