Our surge arrester ceramic capacitor elements serve as voltage grading capacitors inside metal-oxide surge arresters (MOSA). These high-voltage ceramic capacitors ensure uniform voltage distribution across the ZnO varistor stack, improving arrester performance and extending service life in 10kV to 35kV power systems.
Built with premium ceramic dielectric formulations, our elements withstand repeated impulse voltages and harsh outdoor conditions, delivering stable capacitance under thermal cycling and pollution exposure.
