ESE Lightning Rod EarlyHD-T5.3 Advance Discharge Lightning Rod Lightning Protection SystemESE Lightning Rod Early HD-T6.3 Advance
Discharge Lightning Rod Lightning Protection SystemHD-T6.3/0.5 advance discharge lightning rod made of special stainless steel material, needle (needle) height 500mm, receiving flash capacity 200KA, with simple installation, corrosion resistance, suitable for direct lightning protection of small objects. Can also be installed with lightning rod installation bracket will be installed in a relatively high position, as a standard receiver use.
Lightning rod protection radius as shown in the figure.
Lightning rod body using threaded connection, needle rod and flange plate using on-site welding, installation and fixing according to the site will be flange plate fixed root can be, while the lead wire and flange plate connection, can be fixed in the flange plate can also be welded on the steel pipe, can also be fixed directly on the daughter wall above.
Grounding resistance requirements. 10 ohms.
"HDE" lightning rod in the traditional lightning rod based on the addition of an active trigger system, this trigger system can establish a repetitive high-voltage pulse signal, in the discharge process in due time to produce a continuous discharge path and thundercloud downstream pilot rendezvous, the lightning current into the earth.
"HDE" through a combination of pulse transformer and oscillator to achieve a strictly controlled frequency and amplitude of high-voltage signal emission technology; its energy from the electrostatic field and electromagnetic field and transformed into a high-voltage signal to the tip of the needle, generating a large number of ions, this function so that "HDE" issued by the upstream pilot to advance away from the lightning rod tens of meters or even hundreds of meters and the downstream pilot from the thundercloud to meet the flash, thus expanding the protection range of the lightning rod.
1．2 “HDE” The workflow of lightning rod
Thundercloud formation when the thundercloud prompted the formation of electromagnetic fields between the ground and the clouds, the magnetic field strength at ground level can exceed 14KV/M.
a) At this time, the lightning detector in advance of the discharge lightning rod will detect a certain electromagnetic signal
b) then the detected lightning signal by the sensor will signal transmission to the trigger device
c) trigger device will signal amplification to prompt the next level of high-voltage generator action
d) high voltage generator will generate high voltage to the high voltage pulse generator
e) High-voltage pulse generator will be high voltage oscillation after the generation of electric ions directly to the stainless steel electrode
f) stainless steel electrode tip of the electric ion through the venturi effectively to the tip of the lightning rod.

other important places in higher architectural buildings.
Pre-discharge
When the lightning rod is cut off by lightning, the lightning
received by the lightning body, through the lightning waveform
processing device, using the shell and the centre grounding rod
between the 3mm gap, constituting a coupling capacitor, while the
shell through the inductive coil grounding (centre grounding rod)
When the downstream inducer is close, due to the high frequency.
The inductor is in an open circuit state and the capacitor presents
a short circuit characteristic for high frequencies, so that the
electric field strength on the surface of the flash catcher
increases rapidly under the action of the coupling capacitor until
the avalanche process is triggered, thus releasing the lightning
current to the ground in an instant and effectively achieving
lightning safety.
