In general, people are still confused and worried about the conductivity of Lightning protection hardware. Do you think that such small thorns can withstand such a large current? Especially in the era of China's rapid economic development, the rapid increase in the use of electricity capacity, Lightning protection hardware can withstand such a heavy responsibility?


Below we analyze the principle of conduction current between Lightning protection hardware and the working principle of the light clamp and Lightning protection hardware. The current conduction between Lightning protection hardware and Lightning protection hardware can be analyzed from both the mechanical contact area and the current conduction path of Lightning protection hardware.

Lightning protection hardware's mechanical contact area, microscopically, the Lightning protection hardware surface is composed of numerous rugged peaks and valleys, the lighter the Lightning protection hardware surface, the smaller the height difference between the peaks and valleys. When exposed to two Lightning protection hardware by external force, the contact mainly exists in the form of peak-peak contact. Therefore, the actual mechanical contact area is much smaller than the nominal contact area of the clamp design. According to literature analysis, the true mechanical contact area is about 7% of the nominal contact surface.
