Double spherical lightning rod product introduction:
   The double-spherical optimized lightning rod is a non-inductive low-impedance metal inner conductor that passes through the down conductor todeliver lightning current after lightning to the earth, so that the protected antenna tower or building does not have side impact and electrification. In most cases, the impact of the electrostatic field cable is less than 1/10 of theimpedance of the tower , avoiding the charging of buildings or towers and eliminating flashovers. The spherical lightning arrester has the largest feature coverage area and strong lightning discharge capability.
Double spherical lightning rod features:
   1. It is triggered by the electric field principle, and there is no electronic device that can be aged inside, so that it is truly maintenance-free; it is especially suitable for places that cannot be repaired after installation, such as churches and building spires, which are often difficult to reach;
    2 , using stainless steel material, so that it can work normally in chemical pollution places;
   3. The ionizing ball can effectively and quickly ionize the ball-like gas when the lightning is generated, thereby achieving the purpose of optimizing the discharge.
   4 , the standard height of the ball lightning rod is 1.2 meters, 1.5 meters, 2 meters, 2.5 meters, 3 meters, 4 meters, 5 meters (including the flange), and an extension rod is also available .
Double spherical lightning rods : mobile communication base stations, buildings, explosives warehouses, warehouses, oil depots, pump stations, satellite stations, airport equipment, meteorological stations, petrol gas stations, military bases, communication base stations, etc.;

Double spherical lightning rod installation method :
    1. The cement base should be placed in the installation position in advance, and the anchor bolts or expansion screws should be embedded.
   2. Install the lightning rod. The base of the lightning rod is fixed on the pre-set prefabricated cement base. The base of the lightning rod tower is reliably connected with the anchor bolt of the cement base (or with expansion screws).
    3. The lightning rod should be installed on the tower, tower or other building. The flange of the lightning rod must be 1.5m or more higher than the highest protection. According to this requirement, the height of the pole or the height of the tower should be set.
    4. The distance between the independent lightning rod and its grounding device and the entrance and exit protection of the road or building shall comply with the regulations. The distance shall be greater than 3m. When less than 3m, the pressure equalization measures shall be adopted or the pebble or asphalt ground shall be laid.
    5. Installation and testing of lightning rods are not allowed on thunderstorm days.
    6. The grounding wire of the lightning rod must be reliably connected to the earth. The value of the grounding resistance should meet the requirements of national regulations.
   7. Regular inspection (one inspection per year) Whether the lightning rods are connected to the screw and the welding joint is firm, and whether the grounding down conductor is reliably connected to the grounding system. If it is found that the connecting screw and the welded joint are seriously corroded, the screw must be replaced and the original welded joint should be re-welded.
