Optimized Lightning Rod, Direct Strike Protection 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 earth 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. It then travels through the grounding downrods and grounding equipment to channel the lightning current into the earth, thereby protecting the object from lightning strikes.
