Maxwell Technologies, Inc. Gas-Insulated Switchgear (GIS) Grading Capacitor

Gas-insulated switchgear (GIS) circuit breakers for tough environments with extreme temperature variations, dust, pollution or confined space use grading capacitors to ensure a uniform distribution of the voltage across the breaking chambers. CONDIS® GIS capacitors have a sophisticated design—its electrical insulation is made by a vacuum impregnated epoxy resin tube with a smooth external surface. This design guarantees mechanical robustness and oil- and gas-tightness within a high pressurized environment in a large, specified temperature range. Our capacitors are partial-discharge-fr ee and have a proven record of high performance and reliability with years of in-field operation. High-voltage GIS capacitors are compliant to the standard IEC62146-1; they can be used in various types of gas-insulated switchgears, and their design is therefore customer-specific. Independent of the application, the flanges, tubes, and field distribution will remain unchanged along the insulator.
