Protection against lightning overvoltage at the incoming end of 220/264kV substations, high and low voltage sides of transformers, and transmission lines, limiting the amplitude of overvoltage to below the equipment tolerance level; Power frequency continuous current cutoff reduces equipment damage and maintenance costs caused by lightning strikes. As the primary line of defense, the Histe high voltage surge arrester is engineered to perform these vital protective functions with unmatched durability and precision.
Composite jacket type is used in coastal salt spray and industrial pollution areas, combined with pressure equalization rings to enhance stability.
Priority should be given to fully sealed zinc oxide lightning arresters in high-altitude areas to avoid seal failure caused by pressure changes
