This product is a high insulation lightning protection system. It uses the lead down (lightning protection cable) with pulse resistance voltage of 600kV (1.2/50μs), so that the instantaneous high current such as direct lightning strike does not flow through the tower or the reinforcing bar of the building, and is released smoothly in the ground pole buried in the ground place of the equipment.

※ (The lightning protection cable is not sold separately and needs to be sold as a whole with the lightning protection system, so please feel free to contact us if you want the lightning protection system 600)
