How Franklyn Lightning Rod functions - It attracts and receives the direct lightning, approaching the structure and dissipates the high voltage lightning currents into the earth mass through conductors, thus preventing damages to the structure/building and fire hazards
Franklyn Penta 1.0 Cu : Ashlok designed Franklyn type Lightning Conductor, Made of Copper material the air terminal consist of metal sphere having 5 spikes fixed vertically at different angles. The sphere is connected with a vertical rod having a suitable base plate to fix it over horizontal plain surface. The protective conductor is connected at base plate at one end and other end is connected with Earth Rods. The Lightning current gets attracted towards air terminal and safety passes through the protective conductors laid in a pre-determined route and dissipates in to the ground | Mother earth through earthing system.
