Lightning and operational overvoltage protection for 66/72.5kV substations and transmission lines is critical to reduce the risk of equipment insulation breakdown. The Histe high voltage surge arrester is engineered to provide this crucial defense by safely diverting transient overvoltages to the ground. In high pollution and ice covered areas, its performance can be further enhanced with pressure equalization rings or anti-fouling flash coatings to ensure long-term stability.
Composite jackets with a protection level of IP65 are preferred for industrial plants and coastal salt spray areas.
In frequent thunderstorm scenarios, it is recommended to use rear plug-in lightning arresters that support multi-angle installation
