The design of our metal oxide surge arrester consists of zinc oxide (ZnO) discs, making it highly effective for lightning protection. The nonlinear characteristics of zinc oxide eliminate the need for series gaps, resulting in a reliable gapless design.

The metal oxide discs are arranged in a stack and enclosed in a durable polymer or porcelain housing. Spring-loaded cups at both ends secure the stack, with electrodes for earth and line connections. The housing is completely filled with fiber-reinforced composite material, creating a solid component with threaded studs on each end.

Lightning strikes during thunderstorms pose significant threats to electrical systems, potentially causing equipment damage and power disruptions. Our lightning arrester provides reliable protection against these hazards.
