lightning rod
A lightning rod is a metal rod or conductor that is installed on buildings or structures to protect them from lightning strikes. When lightning occurs, the rod provides a safe path for the electrical discharge to travel to the ground, preventing damage to the structure and reducing the risk of fire.
Typically made of copper or aluminum, lightning rods are connected to a grounding system that disperses the electrical energy safely into the earth. This technology is essential for protecting tall structures, such as skyscrapers and communication towers, as well as historical buildings and homes from the destructive effects of lightning.
