It adopts gapless design, eliminating the hidden troubles of gap aging, arc reignition and poor consistency existing in traditional arresters, ensuring stable protection performance. The core component is a high-quality nano-composite zinc oxide varistor chip with high voltage gradient (80-120V/mm), large through-current capacity and excellent energy absorption capacity, which can quickly clamp the overvoltage to a safe range when lightning or operating overvoltage occurs. The ceramic housing is made of high-purity alumina ceramic, sintered at high temperature, with smooth surface, dense structure, strong mechanical impact resistance and thermal shock resistance. It can be equipped with a frequency division shunt disconnector, which does not malfunction during normal operation and does not refuse to operate when the arrester fails, providing obvious signs of effective and permanent disconnection, realizing maintenance-free inspection of the arrester. The internal filling of arc-extinguishing materials can effectively eliminate the reliability of internal arc establishment, prevent internal flashover and eliminate porcelain sleeve explosion. It supports vertical installation, can be flexibly matched with 110kV power grid equipment, and is an essential protection device to improve the safety and reliability of the power system.
