OMEGA X25 X45 X60 Early Discharge Lightning Rods, Pre-Discharge Lightning Rods, Early Discharge Time 25µs, 45µs, 60µs
France OMEGA:Ω-X Advance Discharge Lightning Rods Product Description:
France OMEGA: Ω-X early discharge lightning rod working principle is to produce a faster than ordinary lightning rod upstream pilot, early flash, the protection range is larger than ordinary lightning rod.
OMEGA: Ω-X early discharge lightning rod developed by the French PIORTEH & WRWELS group of companies, the company has obtained ISO9001 certification, holds the INERIS (France's environmental protection agency) certificate, the company's products are sold in more than 30 countries and regions of the world, widely used in buildings, aviation, and petrochemical enterprises, such as: Paris Invalides (Napoleon's tomb), the Pantheon, De Gaulle Airport, Copernicus Memorial in Poland, the world's tallest bridge in France, Miyo Bridge, the Polish cathedral and other famous buildings are used. The products have passed the test reports of EDF, LGE, Beijing Lightning Protection Device Test Center and China invention patent, and the products are underwritten by Pacific Insurance Company.
OMEGA:Ω-X advance discharge lightning rod protection range, France:
According to the French national standard NFC-17-102, when the tip of the ESE (“Early Strike”) is 2m, 4m, 5m, 6m, 7m, 10m and 20m above the object to be protected, the scope of protection is related to the early discharge time ΔT of the lightning rod, the height of the rod and the type of lightning protection of the building: ΔT, ΔT and the height of the rod. Discharge time △ T, needle height and the building's lightning protection category:
Let the start-up preemption time of Ω-X advance discharge lightning rod be △T, then the upstream pilot distance △L = V × △T
OMEGA:Ω-X lightning rod, FranceThe protection radius RP is calculated by the following formula:
1, D for the electric shock distance, it depends on the level of the protected object, for Ⅰ, Ⅱ, Ⅲ class protection object, D value 30m, 45m, 60m respectively.
2. H is the height from the top of the lightning rod to the protected plane.
3. △T is tested and calculated from the evaluation, which are: 25µs, 30µs, 45µs, 60µs.
4, △ L = V * △ T, usually V = 1.06m / s (pilot speed), L is the upward flash height.

Installation Precautions
The installation of pre-discharged lightning rods must strictly follow the mandatory provisions of the National Standard of the People's Republic of China - Code for Lightning Protection Design of Buildings (GB 50057-2010):
1, according to the area of the protected building, height, location of the number of days of lightning and geographic environment correction factor, the nature of the use of the building to determine the category of building lightning protection.
2, by the lightning protection category and the area of the building, to determine the selection of a lightning rod or several.
3. The lead wires shall be electrically connected to the main steel reinforcement of the building, or at least two or more lead wires shall be made according to the regulations.
4. The lead wires should be disconnected and insulated on the ground in the vicinity.
5, grounding body, grounding resistance should be implemented in accordance with the requirements of GB 50057 -2010.
