1.Working Principle: ZnO arrester is used to protect equipment in power systems from overvoltage. When overvoltage appears in the system, the ZnO arrester will conduct, directing the overvoltage to the ground wire, thus protecting the equipment.
2.Advantages:Eliminate Spark Discharge: ZnO arrester eliminates spark discharge and reduces the risk of the system.
3.Current Sharing: Multiple columns of ZnO blocks can be used in parallel to meet high energy requirements. With good current sharing, the energy absorption capacity of these blocks can be effectively utilized.
4.Gapless Design: ZnO arrester adopts a gapless design and does not require a voltage grading system.
ZnO arrester is a reliable and efficient device used to protect equipment in power systems from overvoltage.
