Surge Arrester

Surge arresters are protective devices used in power transmission and distribution systems to safeguard equipment from over-voltage surges caused by lightning or switching operations. Made with high-quality zinc oxide (ZnO) elements housed in porcelain or polymer housings, they feature excellent protective performance, fast response, and strong durability. Surge arresters effectively limit over-voltage, extend the service life of electrical equipment, and ensure safe and stable grid operation.
