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

Lightning rod, also known as a lightning arrester or grounding rod, 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 ground 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 close to the ground, they distort the ground's electric field. At the tip of the lightning rod, a localized space of concentrated electric field is formed to influence the direction of development of the lightning leader discharge, guiding the lightning to discharge onto the lightning rod, and then through the grounding conductor and grounding device, the lightning current is channeled into the earth, thereby protecting the object from lightning strikes.
