Station Class Arresters

Station Class Surge Arresters represent the highest level of overvoltage protection for critical substation equipment, such as large power transformers, reactors, and capacitor banks. These arresters are characterized by their superior energy handling capabilities and high cantilever strength, making them suitable for the most demanding utility applications. Whether installed in AIS (Air Insulated Substations) or integrated into complex switchgear, our station class units provide a low protective level (LPL) to extend the lifespan of your primary assets. Available in both Silicone Rubber and Porcelain housings, these devices are rigorously tested for thermal stability and seismic resistance, providing a “heavy-duty” shield for national grids and large-scale industrial power plants.
