The main types of arresters include tube-type arresters, valve-type arresters and zinc oxide arresters. The main working principles of each type of lightning arrester are different, but their working essence is the same, which is to protect communication cables and communication equipment from damage. Zinc oxide arrester is a kind of lightning protection equipment with good protection performance, light weight, pollution resistance and stable performance. It mainly uses the good nonlinear volt-ampere characteristics of zinc oxide to make the current flowing through the arrester at normal operating voltage extremely small (microamperes or milliamperes); when overvoltage occurs, the resistance drops sharply and the overvoltage is discharged. energy to achieve the effect of protection. The difference between this kind of arrester and traditional arrester is that it has no discharge gap and uses the nonlinear characteristics of zinc oxide to play the role of discharge and breaking.
The above introduces several types of lightning arresters. Each type of lightning arrester has its own advantages and characteristics and needs to be used in different environments to achieve good lightning protection effects.
