  • SF6 Free Gas Handling - us.dilo.com

    SF 6 Free Gas Handling Alternatives to SF 6. The so-called Alternative Gases are alternatives to SF 6, the preferred insulating and arc-quenching gas used in switchgear in the last few decades.While SF 6 has excellent dielectric properties, it is also the most potent greenhouse gas with a GWP of 23,900. Ideally, SF 6 should be used in closed loop systems and never be emitted into the atmosphere.

  • SF6: Does its Impact Outweigh its Benefits? | TD World

    Powerplant and substation electrical staff are very familiar with sulfur hexafluoride or SF6 which is a common insulating gas used in electrical equipment like electrical switches and circuit breakers. For many decades, SF6 has been the go-to dielectric insulating material for high-voltage electrical systems installed in enclosed spaces.

    An SF 6 alternative designed to reduce greenhouse gas impact by 99%. The electric industry has been willing to accept the challenges of using SF 6 as an insulating gas because of its dielectric properties and reliability. But SF 6 is a potent greenhouse gas with a global warming potential 23,500 times that of CO2 when compared over a 100-year period. In fact, it is the most potent greenhouse
