Optimized Lightning Rod, Direct Strike Protection and Air Terminal for High-Rise Buildings, Discharge Lightning Rod

Lightning rod, also known as a lightning arrester or lightning conductor, 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 direction of the lightning leader discharge, directing the lightning to discharge onto the lightning rod. It is then channeled through the grounding downrods and grounding equipment into the earth, thereby protecting the object from lightning strikes.
