In gas-insulated switchgear (GIS), the main busbars carry high voltage and high current, but auxiliary devices like gas filling switches require only small currents for operation. These switches can be connected using small cross-section busbars or flexible busbars, which provide reliable electrical connections without the need for full-sized conductors .
For a gas filling switch, a small, flexible, or low-current busbar connection is feasible and commonly used in modern GIS and switchgear systems. Flexible busbars like Ultraflexx® or Isoflexx® provide reliable, vibration-resistant connections, while solid copper or composite busbars can be used when minimal voltage drop or weight considerations are important . These solutions ensure safe and efficient operation of auxiliary devices without requiring full-sized high-current busbars.
