MS Copper Bonded Conventional Type Lightning Arrester is a traditional lightning protection device designed to safeguard structures from direct lightning strikes. It consists of a mild steel (MS) rod with a bonded outer layer of copper, combining the mechanical strength of steel with the high conductivity and corrosion resistance of copper. Installed at the highest point of a building, the arrester provides a preferred path for lightning discharge, directing the surge current safely to the ground through a down conductor and grounding system. This type of arrester operates on the principle of providing a sharp-pointed conductor to attract lightning within a defined protective zone, typically following a 45-degree angle of coverage. It is widely used in residential, commercial, and industrial buildings due to its durability, cost-effectiveness, and compliance with conventional lightning protection
