First, the principle of lightning rod
In thunderstorm weather, when charged clouds appear over high-rise buildings, lightning rods and the top of high-rise buildings will induce a lot of charges. Because the lightning rod is pointed, the tip of the conductor always collects the most charge when conducting electrostatic induction. In this way, the lightning rod collects most of the charge. The lightning rod and these charged clouds form a capacitor. Because it is pointed, that is, the two plates of this capacitor are opposite in a small area, and the capacitance is very small. In other words, it can hold very little charge, and it collects most of the charge. So when there is more charge on the cloud, the air between the lightning rod and the cloud will be easily broken down and become a conductor. In this way, the charged clouds and the lightning rod form a channel, and the lightning rod is grounded. Lightning rod can transfer the charge on the cloud to the earth, so that it will not cause danger to high-rise buildings and ensure their safety.
Second, the lightning rod brand

Western porcelain
Xi 'an Xidian High-voltage Electric Porcelain Co., Ltd. (formerly Xi 'an High-voltage Electric Porcelain Factory) was formed by the merger of two key construction projects (high-voltage electric porcelain and lightning arrester) aided by the former Soviet Union during the First Five-Year Plan period. 1953 was established and 1959 was put into production. In September of 200 1 year, it was restructured into Xi 'an Xidian High-voltage Electric Porcelain Co., Ltd., which belongs to china xd Group.
Zhongguang
Sichuan Zhongguang Lightning Protection Technology Co., Ltd. is the earliest lightning protection company in China, established in 1987. In 2003, the sales reached more than 200 million, and it will be listed on 20 12. It has a provincial-level technical center in Sichuan Province, a nationally recognized laboratory, a lightning protection engineering research center and an automated production line, with strong strength. It is the largest lightning protection enterprise in China.
Third, the selection points of lightning arrester
Mainly includes the following aspects:
1, conditions of use, such as pollution level.
2. Continuous working voltage of lightning arrester to ground.
3, relative to the rated voltage of lightning arrester.
4, power frequency withstand voltage time characteristics.
5. Lightning discharge current.
6, long duration discharge ability.
7. Insulation matching coefficient.
8. Pressure release grade
Lightning rod is used to protect buildings, trees and other equipment from lightning, which is related to our personal safety and cannot be careless. Buying things still depends on the brand, and everyone can't go wrong. This is the end of the introduction of lightning rod brand, I hope it will be helpful to everyone.
