G.I. Lighting Arrestor

A G.I. lightning arrestor is a lightning protection device made from galvanized iron, installed at the highest point of structures to intercept lightning strikes and safely conduct the surge current to the ground. It forms part of a lightning protection system that includes down conductors and an earthing network. Typical technical characteristics include galvanized steel construction for corrosion resistance, high mechanical strength to withstand weather conditions, pointed air terminal design for effective strike interception, compatibility with GI strips or wires as down conductors, and suitability for buildings, towers, industrial plants, and substations to protect equipment and structures from lightning damage.
