Lightning rods are used to protect power plants, substation power installations, individual line sections, industrial and civil high-rise buildings. The lightning rod is directly grounded. The height of the needle is higher than that of the bar. In the process of the lightning circuit extending to the ground, due to the impact of the power plant, the lightning rod will gradually rotate and hit the lightning rod, thus avoiding the development of lightning bolts directed at the protected equipment. The device is ideal for protection against direct lightning strikes.
