Lightning rods, also known as lightning rods, are devices used to protect buildings and tall trees from lightning strikes. Install an air-termition device on the top of the protected object, and connect it with a wire that meets the specifications and the underground draige network. When the thundercloud discharges close to the ground, it distorts the ground electric field. At the top of the lightning rod, a space with a local electric field concentration is formed to influence the development direction of the lightning pilot discharge, guide the lightning to discharge to the lightning rod, and then introduce the lightning current into the earth through the grounding down conductor and grounding device, so as to protect the protected object from lightning strikes.
