Maxwell Technologies SA – CONDIS® HV Capacitors Typical GIS Capacitor Design HV GIS capacitors are dedicated to various types of Gas Insulated Switchgear, and the design is therefore customer-specific. The general design can be seen in the outline drawing above. Independent of the application the flanges, tubes, and field distribution will remain unchanged. Backward compatibility with our former technology is 100% guaranteed. However, the CONDOR technology will often permit new concepts and designs, i.e. by higher capacitance in a given space. The table below shows selected types of GIS...
