Description
36kV metal oxide arrester is a non-linear type, 10kA distribution class lightning arrester without spark gaps, which works for 50HZ a.c. power system with the highest voltage of 36kV. When the arrester fails abnormally, the power frequency short-circuit current is used to make the disconnector act, so that the grounding terminal of the disconnector is automatically disengaged, and the arrester stops running to prevent further expansion of the accident, and the faulty arrester is given a visible disconnection mark, which is convenient for maintenance personnel find fault points in time for maintenance and replacement.
Product Feature
Packing
To protect the product during land, air, or sea transport, all insulators will be packed in weatherproof containers. Several different grades of packaging are available depending on the mode of transport and expected storage conditions. Special packaging arrangements are available upon user request.

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.
