grounding wire, grounding rod, household grounding pin, lightning protection grounding, building lightning rod.
Brief introduction
The lightning rod should be directly grounded, and the
discharge phenomenon at the tip of the charge is not allowed to
happen. The lightning rod is separate from the protected object,
and it can protect the important objects that are more
concentrated. The lightning rod is actually a mine needle, the
general lightning rod is higher than all the protected objects, the
top of the lightning rod is a metal tip, the bottom is well
connected with the grounding grid, and the grounding resistance is
generally below 10 ohm. In thunderstorm weather, due to the strong
distortion of the top tip to the electric field, it attracts the
nearby thundercloud to discharge the tip of the lightning rod, and
protects the other objects from lightning through good grounding
neutralization and the charge of the thundercloud.

Working principle of product
In the thunderstorm, the lightning rod and the top of the
tall building are induced by a large amount of charge when there is
a charged cloud over a high building. Because the needle of the
lightning rod is sharp, the most charge is always gathered at the
tip of the conductor when the electrostatic induction is induced.
In this way, the lightning rod congregates most of the charge. The
lightning rod also forms a capacitor with the charged clouds, which
is relatively small because the two pole of the capacitor is small
and the capacitance is very small, that is to say, it can hold very
little charge. When it charges more clouds, the air between the
lightning rod and the cloud layer can easily be breakdown and
become conductor. In this way, the charged cloud layer and the
lightning rod form the path, and the lightning rod is grounded, the
lightning rod can import the charge on the cloud layer into the
earth, so that it does not pose a danger to the high-rise building
and ensures its safety.
Use of attention
1.The distance between the lightning needle and earthing
device from the road and exit should be greater than 3m, otherwise,
the gravel or asphalt surface should be 5 to 8cm thick, so that the
protection of the insured is not affected by step voltage.
2. way is to install overhead lighting lines,
telephone lines, broadcasting lines, antennas, etc. on lightning
rods or frames.
3. if the lighting lamp is installed on the independent
lightning rod or frame, the power wire must be leaded or penetrated
into the steel pipe and directly buried in the ground for more than
10m.
