Advantages of sulphur hexafluoride in gas-insulated switchgears. SF 6 insulation allows safe operation of high- and medium-voltage systems in close areas, since insulation with sulphur hexafluoride requires much smaller safety clearances. Non-dispersive infrared gas sensors (NDIR sensors) from smartGAS are ideal for measuring the SF 6 gas quality and for detecting even very small quantities of the harmful gas.

Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

Sulfr hexafluoride is used in GIS – gas insulated system at pressures from 400 to 600 kPa absolute. Wide range of pressure The pressure is chosen so that the Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. sf6 gas has two to three times the insulating ability of air at the same pressure.
