Surge arrester
Zinc-Oxide Arrester is widely used in the power system for the overvoltage protection, because it has high through-flow capacity and good nonlinear characteristic. It can protect the equipments in Alternating Currenlt Power System from over-voltage effectively. We can manufacture arresters with rated voltage from 0.22kV to 220kV. Uder below is the main electrical parameter of ther type you can refer to.
