1)Product description:
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.

3)Product installation:
1.Pour in advance cement base at the installation location , size 400mm × 400mm × 600mm (length X width X height) and embed anchor bolts or expansion screws.
2. Installation lightning rod: Fix the base set of lightning rod to pre-cast concrete base,then link reliably the lightning rod tower base and cement base with anchor bolts (or expansion screws) .
3. The lightning rod should be installed in the tower, tower or other buildings, the flange plate of lightning rod must be higher above 1.5m than the highest protection , according to this requirement to heighten tower or set tower height.
4. Get rid of installing and testing of lighting rod on the thunderstorm day.
5. The grounding wire of lightning rod must be connected with a reliable grounding rods, ground wire is green and yellow color and its cross-sectional area is BVR25mm2 multi-strand copper wire.
6, Make regular inspections (once a year) to make sure the connection of the lightning rod the screw, welding is solid or not, ground downlead is connected with the grounding system reliably or not.If we find that connection of the screw, weld is corroded serious,we shall replace the screw to re-connect, re-soldering the original weld.
