Pre-discharge current-limiting lightning rod

Ⅰ. Product description:

The pre-discharge current-limiting lightning rod is a non-inductive, low-impedance metal inner conductor leading down the wire, which transports the lightning current after the flashover to the ground, and prevents the protected antenna tower or building from side strikes and electrification.In most cases, the impact of the electrostatic field cable is less than 1/10 of the impedance of the tower, which prevents the building or tower from being charged and eliminates flashover; limits the current intensity of the mine, so that the protected equipment reduces the hazards of counterattack and induced overvoltage .

The direct lightning protection devices for buildings are composed of air-termination devices, down conductors and grounding devices. The air-termination device directs the lightning current to itself, and leaks into the earth through the down conductor and the ground network. Lightning rod is one of the lightning rods. It has the characteristics of traditional lightning rods to attract lightning to the ground, and it can reduce the amplitude, wavelength and wave head steepness of the incoming mine current at the same time, so that people, electronic equipment, and electronic equipment within the protection radius of the lightning rod can be reduced. Power facilities, communication lines and various buildings are protected from direct lightning strikes.

Early discharge current-limiting lightning rods are widely used in first, second, and third types of lightning protection buildings, such as: mobile communication base stations, buildings, warehouses, oil depots, water pumping stations, satellite stations, airport equipment, meteorological stations, petroleum gas stations, Military bases, etc.

Ⅱ. Main feature:

A. Large coverage area, strong lightning discharge current

B.Significantly reduce the lightning induction when the lightning current passes through the lightning rod and the down conductor

C. The ground current is small, reducing the potential difference formed by the current entering the ground and the counterattack phenomenon appears

D. Reduce the overvoltage phenomenon caused by the large current that appears in the down conductor
