Metal-oxide surge arrester with disconnector

Product introduction
The disconnector is used in series with the arrester. Utilizing the fault current when the arrester is damaged, the disconnector will generate electric arc and heat, act quickly to make the arrester out of operation in order to prevent the system from single-phase fault. The action of the disconnector has distinct disconnection sign, and the line fault point is easy to be found, improving the operational stability and safety of the electric power system. The arrester can be fixed with discharge counter or online monitor to record the number of arrester actions and the leakage current.
