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

Lightning rods, also known as lightning arresters or air terminals, are devices 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 network using compliant wiring. The specifications of lightning rods 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.
