1,Early electro-discharge time is about 30 subtle

2,The protection radius of the common lightning rod is several times larger than that of ordinary lightning conductor,The same installation height.

3, It consists of three systems, Double instantaneous electro-discharge device, don't have to maintain, There is no aging.

In a thunderstorm, when charged clouds appear over tall buildings, the lightning rod and the top of the tall building will be induced with a large charge, and because the lightning rod needle is pointed, the tip of the conductor will always gather the most charge when electrostatic induction occurs. In this way, the lightning rod gathers most of the charge. The lightning rod and these charged clouds form a capacitor because it is relatively pointed, which means that this capacitor has a very small area of positive polar plates and a very small capacitance, which means that it can hold very little charge. And it gathers most of the charge, so that when there is more charge on the cloud, the air between the lightning rod and the cloud is easily broken through and becomes a conductor. In this way, the charged clouds and the lightning rod form a pathway, and the lightning rod is earthed. The lightning rod can channel the charge on the clouds into the earth so that it does not cause harm to the high-rise building and ensures its safety.

1. All metal parts must be galvanised and care must be taken to protect the galvanised layer during operation.
2. The wall thickness of the tube shall not be less than 3mm and the length of the tip brushed with tin shall not be less than 70mm when using galvanised steel tubes for the tip of the pin.
3. 3. Lightning rods should be installed vertically and kept firm. The permissible deviation of verticality is 3/1000.
4. welding requirements welding should be used lap welding, its lap length must comply with the following provisions.
5. flat steel is twice its width (and has at least 3 prongs welded).
6. round bars are 6 times their diameter.
7. 6 times the diameter of the round bar when connected to the flat bar.
