I want to inquire

【a brief introdction】

ESE pre-discharge lightning rods are simple to install: they are lightweight and do not require the installation of coaxial shielded cables. Corrosion resistance and strong wind resistance. Beautiful shape

△ T: According to the start-up preemption time stipulated by French International NFC17-102, the actual test value is greater than the specified value
ESE pre-discharge lightning rod protection radius

According to NFC17-102, the needle tip should be more than 2m (h1) above the level of the protected object. When the height of the lightning rod is different (h2, h3, ... hn), the protection range (radius) is Rp2, Rp3 ... Rpn, and the calculation formula should consider the lightning protection level of the protected object, local thunderstorm activity and geomorphology.

The protection radius of "satelit +" is related to the height (h), its start-up preemption time (model), and the selected protection level:

When h≥5,

Note: In the formula, Rp is the protection radius on the horizontal plane under consideration, h is the horizontal height difference between the tip of the needle and the top of the protected object, and D is the ball radius (flashing distance).

* Class buildings are 20m (GB50057-94 regulations D = 30m)

The second type of building is 45m

The third type of building is 60m

△ L is the upstream preemptive distance of "satelit +"

△ L = V (meter / microsecond) · △ T (microsecond)

V is the pilot propagation speed. Experimental data shows that V = 1 m / microsecond.

When h <5, see protection radius table
