  • SF6 gas in medium-voltage switchgear | TD Guardian

    In this issue, we discuss the use of SF6 (sulfur hexafluoride) gas in medium-voltage switchgear. SF6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

    The global gas insulated switchgear market for medium voltage is forecast to grow over 8% per annum through 2022. In certain markets, minimizing or eliminating SF 6 emissions is increasingly prioritized. However, currently even best practices are self-imposed and not widespread due to scant legal obligation on SF 6 emissions. Since switchgear typically has a lifetime of 40-50 years, it is critical to act now.

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    But 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 earths atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to
