SF6 (or Sulphur Hexafluoride) has been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF6 is also listed as a potent greenhouse gas according to the Kyoto Protocol, with 24,300 times the comparative Global Warming Potential (GWP) of CO2 and a lifetime of 1,000 years in the atmosphere. With grid operators across the world becoming increasingly concerned about the environmental impact, we offer a commercially available and viable alternative to SF6 to help utilities and industries reduce their environmental impact.
