Zinc oxide lightning arrester is a lightning arrester with good protective performance. Utilizing the excellent nonlinear volt-ampere characteristics of zinc oxide, the current flowing through the lightning arrester at normal operating voltage is extremely small (microampere or milliampere level); When overvoltage occurs, the resistance drops sharply, releasing the energy of overvoltage to achieve protection.
1.Current handling capability: Surge arresters can effectively deal with various types of overvoltages, including lightning overvoltages, power frequency transient overvoltages, and operational overvoltages, demonstrating strong current handling capabilities.
2.Protection advantage: Zinc oxide lightning arrester, as an electrical protection equipment, plays a crucial role in the power system. It can protect various electrical equipment from overvoltage damage and demonstrate excellent protection performance.
3.Sealing reliability: the lightning arrester components use high-quality composite jackets, which not only have good anti-aging performance, but also have excellent air tightness.
4.Anti pollution capability: Zinc oxide lightning arresters have been designed with full consideration of anti pollution performance, thus possessing high anti pollution capability.
