  • The difference between 2-electrode surge arrester and 3-electrode surge arrester

    The discharge electrodes of the gas discharge tube are generally two, three or five. The electrodes are separated by inert gas. According to the number of electrodes, they are divided into two-pole gas discharge tubes or three-pole gas discharge tubes.                 n the design of lightning pr...

  • The prnciple of Switching Spark Gap

    The principle of gas discharge can be used not only for overvoltage protection, but also for switching spark gap(https://www.zhengmaoelec.com/products/switching-spark-gap/). Different from the gas discharge tube, the SSG is an active component, and after dozens of ignitions, it still has stable p...
