Application
High-voltage zinc oxide arresters are mainly used to protect equipment and lines in power systems from damage by lightning strikes and overvoltage. It can quickly introduce the increased overvoltage into the ground to ensure the safe operation of the power system. In addition to power systems, high-voltage zinc oxide arresters are also widely used in petrochemical, transportation, communications and other fields. For example, on the highway, the arrester on the street light pole is a high-voltage zinc oxide arrester. In petrochemical plants, high-voltage zinc oxide arresters can effectively protect equipment from lightning strikes and electrostatic interference. In the field of communication, high-voltage zinc oxide arresters are also important equipment to ensure the normal operation of communication systems.
