Ball type lightning air terminals is the metal inner conductor downlead with non-inductive, low impedance, after the lightning flash then transport currents to the earth , and protect antenna tower or building get rid of occuring sideswipe and charged. In most cases, the impact of electrostatic field is less than the tower cable impedance 1 / 10, to avoid building or tower live and eliminate flashover.

The biggest feature of Ball type lighting air-termination system is big coverage area and strong lightning discharge.

It is applied to mobile communication base stations, buildings, depots, warehouses, oil tanks, pump stations, satellite station, airport equipment, weather stations, gas stations, military bases, communication base stations and so on.
