  • SF6 Switchgears - ELECTRONSYSTEM MD

    SF6 is a gas used by switchgear manufacturers in making their equipment because of its unique dielectric and breaking properties. The main use of the gas, although it is used in multiple other industries, is in high and medium voltage switchgears.. When it comes to medium voltage (MV) switchgears, SF6 is the single proposed solution that suits the switchgear.

  • Is the end coming for sulfur hexafluoride, the most

    Oct 15, 2020Current EU F-gas regulation prohibits the use of SF 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use SF 6.When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF 6 were available.

  • Innovative SF6-free Switch with Shunt Vacuum Interruption

    More than 30 million units of medium-voltage switchgear installed worldwide use sulfur hexafluoride (SF6), a potent greenhouse gas. Eliminating the use of SF6 is a significant step toward safer, more environmentally friendly switches. This paper discusses how, beyond boosting safety, an innovative new SF6-free technology is:

  • An alternative to SF6 in electrical switchgear - EE Publishers

    However, SF 6 is a greenhouse gas and the life-cycle management costs incurred when handling SF 6, particularly when the decommissioning of ageing substations, is on the increase. These costs will rise further as the demand for electricity, and, therefore, gas-filled high and medium-voltage switchgear…

    SF 6 (Sulfur hexafluoride) has been a reliable insulation gas used in switchgear for over 50 years worldwide. Although it has excellent insulation qualities, it also has a high global warming potential and is a potent greenhouse gas. Upcoming regulations regarding SF 6 will motivate customers to adopt SF 6-free switchgear technology.

    SF 6 gas is widely employed in medium-voltage switchgear because of its high insulation reliability and down-sizing ability. However, SF 6 gas was placed on the list of greenhouse gases under the Kyoto Protocol in 1997. Since then, research on low-SF 6 or SF 6-free insulation has been carried out actively. Therefore, we focused on solid
