Product Description
Ceramic Capacitor Elements for Medium Voltage Surge Arresters | 10kV–35kV Grading Capacitors

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.

Key Features
  • Optimized for 10kV, 24kV, 35kV surge arrester designs
  • High impulse voltage withstand capability
  • Stable capacitance under wide temperature variation
  • Low dielectric loss under continuous operating voltage
  • Resistant to moisture, pollution and UV degradation
  • Custom diameter and height to fit arrester housings
  • Compatible with both porcelain and polymer housed arresters
Applications
  • Medium-voltage metal-oxide surge arresters (MOSA)
  • Distribution class and station class arresters
  • Overhead line and substation surge protection
  • Wind farm and solar plant lightning protection
  • Capacitive grading inside polymer insulator assemblies
