Power line safety warning lamp is a new type of device used for outdoor overhead power lines (covering the fields of transmission, distribution, and consumption etc., high, medium and low voltage levels). It is often installed in places where power lines easily will be easily damaged, such as Road intersections and construction sites, which serve as a reminder for passing vehicles and construction machinery to prevent scratches and damage to power lines.

The device is installed on the conductor of outdoor overhead power lines, and has the same potential as the power lines. It adopts solar self-charging and built-in rechargeable battery, which can work continuously for 7-10 days in rainy weather (Shimmer). Automatically, the built-in light switch will be off during the day, and the LED light will flash normally at night or in a weak light environment.
