Lightning protection grounding materials are specifically selected and designed to safeguard structures and electrical systems from the destructive forces of lightning strikes. The key requirement for these materials is high electrical conductivity to provide a low - resistance path for the massive electrical currents associated with lightning. Copper is a widely preferred material due to its excellent conductivity, durability, and corrosion resistance. Copper - based grounding rods, strands, and mesh systems are commonly used, as they can efficiently dissipate lightning energy into the ground. In addition to copper, other materials like copper - bonded steel offer a cost - effective alternative while maintaining good conductivity and mechanical strength. Grounding electrodes made from these materials are often installed in combination with grounding strands to create a comprehensive grounding network. Insulating materials with high dielectric strength are also crucial for protecting the grounding system components from electrical breakdown during a lightning event. These materials work together to form a reliable lightning protection grounding system that minimizes the risk of damage to buildings, equipment, and human safety.
