DUAL-ADE and nuventura announce partnership to bring ... days ago· GIS uses SF 6, or sulfur hexafluoride, as an insulation medium due to its electrical insulating properties. However SF 6 is a potent greenhouse gas - the atmospheric greenhouse effect of one kilogram of SF6 equals that of over 23,500 kilograms of CO 2 and its atmospheric lifetime estimate is over 3,000 years.
