Grading Capacitors are used in combination with High Voltage Circuit Breakers with different purposes.

• Multibreak Circuit Breakers:
  • Grading Capacitors ensure uniform voltage distribution across all contacts points during normal and switching system operation
• Single break Circuit Breakers:
  • Grading Capacitors can be used to increase the switching capacity of the breaker
• 90 up to 300 kV
• Sealed construction, maintenance free
• All external metallic components made by aluminum or inox steel
• High customization range to match CB mechanical and electrical parameters
• High mechanical resistance to shock and vibration due CB‘s switching operation
• Available in compliance with all international standards

GC’s – AIS Circuit Breakers (outdoor installation)

• Synthetic liquid + paper and/or polypropylene insulation
• Porcelain or composite insulator

GC’s – DT and GIS Circuit Breakers (indoor installation inside SF₆  CB’s gas enclosure)

• Synthetic liquid or SF₆  + paper and/or polypropylene insulation
• Fiberglass tube insulator
