Optimized Lightning Rods, Direct Lightning Protection Terminal for High-Rise Buildings, Discharge Lightning Rods

Lightning rod, also known as a lightning arrester or air terminal, is a device used to protect buildings and tall trees from lightning strikes. A lightning rod is installed at the top of the protected object and connected to an underground grounding grid with a compliant wire. The specifications of the lightning rod must comply with national standards, and the height specifications required for each lightning protection category vary.

When lightning clouds discharge near the ground, they distort the ground's electric field. At the top of the lightning rod, a localized area of concentrated electric field is formed to influence the development direction of the lightning leader discharge, guiding the lightning to discharge onto the lightning rod, and then through the grounding down conductors and grounding devices, the lightning current is channeled into the earth, thereby protecting the object from lightning strikes.
