Problems solved by technology

[0005] The existing lightning protection technology mostly uses lightning rods to guide the lightning current to discharge. The grounding wire of the lightning rod is usually buried underground with a large number of metal components for reliable grounding, such as deeply buried copper plates, copper strips and other components. The price of metal materials is high, so the cost is high. Corrosion, including the lightning rod as a whole, is facing the danger of corrosion. After corrosion, the grounding resistance increases, which reduces the grounding performance. It is easy to be damaged by lightning strikes, and even accidents occur, which is not conducive to long-term use.
In addition, steps such as digging pits, placing metal components, and burying metal components are required during specific construction, which is complex and can easily lead to poor electrical connections of metal components during construction, resulting in grounding failures
