First, the zinc oxide arrester has a large flow capacity
This is mainly reflected in the arrester's ability to absorb various lightning overvoltages, power frequency transient overvoltages, and operating overvoltages. The flow capacity of the zinc oxide arrester produced by Chuantai fully meets or exceeds the requirements of national standards. Line discharge level, energy absorption capacity, 4/10 nanoseconds high current impulse withstand, 2ms square wave flow capacity and other indicators have reached the domestic leading level.
Second, the zinc oxide arrester has excellent protection characteristics
The zinc oxide surge arrester is an electrical product used to protect various electrical equipment in the power system from overvoltage damage and has good protection performance. Because the non-linear volt-ampere characteristics of the zinc oxide valve plate are excellent, only a few hundred microamps of current is passed through the normal operating voltage, which is convenient to design a gapless structure, which has good protection performance, light weight and small size. feature. When the overvoltage invades, the current flowing through the valve plate increases rapidly, and the amplitude of the overvoltage is limited, and the energy of the overvoltage is released. Thereafter, the zinc oxide valve plate returns to a high resistance state, so that the power system works normally.
Third, the zinc oxide arrester has good sealing performance
The arrester component adopts a high-quality composite jacket with good aging performance and good air tightness. It adopts measures such as controlling the compression of the sealing ring and adding sealant. The ceramic jacket is used as a sealing material to ensure reliable sealing and stable performance of the arrester.
