Copper three-prong lightning rods are commonly used direct lightning protection devices, featuring multi-tip discharge and high-conductivity copper material. They are widely applied in buildings, photovoltaic power stations, energy storage systems, communication base stations and other scenarios.
Consisting of a three-prong air terminal, copper rod body and base flange, this device works by tip discharge to capture lightning leaders actively. Multi-tip design expands the protection range and reduces current concentration, safely guiding lightning current to the grounding system through down conductors.
· High conductivity: Pure copper ensures fast lightning current transmission with low resistance loss.
· Corrosion resistance: Excellent weather resistance for coastal, industrial and harsh outdoor environments.
· Stable performance: Multi-prong structure improves lightning interception probability and wind resistance.
· Photovoltaic and energy storage power stations
· Industrial plants, villas and high-rise buildings
· Communication base stations and outdoor electrical equipment
· Coastal and high-corrosion areas
· Install at the highest point of the protected structure.
· Ensure reliable electrical connection between lightning rod, down conductors and grounding grid.
· Grounding resistance generally required ≤ 10Ω (≤ 4Ω for critical facilities).
· Comply with lightning protection standards such as GB 50057.
