Therefore, the concept of lightning rods and lightning arresters can be said to be very vague for customers. They all believe that with the addition of lightning rods, they do not need to worry about thunder, and they can guarantee safety. Here, our technical staff and everyone briefly explain the general difference between the lightning arrester and the arrester and their respective roles.
First of all, it is not necessary to add lightning rods to be determined according to the site conditions. If the situation on the site is not very severe (high buildings, lightning strikes, and particularly open areas), it is generally not necessary to install lightning rods. The main role of the lightning rod is to prevent direct lightning hitting the building, commonly known as the mechanical effect, also called direct lightning, the probability of this happening rarely. The function of the lightning arrester is to prevent the secondary effect of lightning strikes. It is a completely different and separate concept. It is also possible to add a lightning arrester to the lightning arrester, and it is possible to add a lightning arrester without a lightning arrester. The addition of arresters is based on the use of electrical equipment at the site. Simply speaking, as long as there are useful electrical equipment and overhead lines, then it is necessary to increase arresters. Only by adding lightning arrestors can we ensure that no electricity will be burned out when lightning strikes. equipment. The main function of the lightning arrester is to prevent the lightning wave invasion and lightning induction. The lightning rod has no such effect.
Therefore, if a lightning rod is installed, if there is a line entering and the use of a useful electrical device, then it is better to increase the lightning protector's secondary protection against lightning strike during the safety period.
Is it necessary to install a lightning arrester after installing a lightning rod?
Recently, many customers called directly to say: "We need to be a lightning rod here please quote us a price." In this case, our technical staff will always ask the customer's on-site situation seriously. Sometimes it is necessary to install a lightning rod according to the site conditions. However, most of the cases are not based on the situation provided by the customer and the equipment to be protected. Install lightning rods, but install lightning arresters.
