Alternatives for SF6 | 2020 | Siemens Energy Global more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earth's atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to ...

Technical Support Document for Process Emissions of Sulfur ... is used in gas-insulated substations, circuit breakers, other switchgear, and in gas-insulated lines. Sulfur hexafluoride has replaced flammable insulating oils in many applications and allows for more compact substations in dense urban areas. Currently, there are no available substitutes for SF6 in high voltage applications.

Sulfur Hexafluoride SF6 - A-Gas is generally transported as a liquefied compressed gas. SF6 allows simplified design of high and medium voltage switchgears because of size and weight reduction, quiet and reliable handling and maintenance. The emission of one kilogram of SF6 is in terms of share of the greenhouse effect is equal to 23.500 kg CO2 emissions.

ALTERNATIVE GAS TO SF 6 FOR USE IN HIGH VOLTAGE ... modern transmission and distribution network relies on SF6 technology because of its remarkable arc quenching properties and dielectric insulation (approximately 3 times greater than air). However, even if SF6 Switchgears are safe for the environment, the SF6 insulating gas has potential significant environmental impacts if it leaks into the atmosphere. Indeed SF6 is one of the six gases ...
