SF6-alternative gases vacuum training

However, SF 6 is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with insulation and arc interruption properties similar to those of SF 6. This mission has now been accomplished and the world's first gas-insulated switchgear (GIS) pilot installation to use a new gas

  • SF6 Training and Certification | EA Technology

    Since the Fluorinated Greenhouse Gas Regulations were revised in 2014, if you carry out any activities that directly involve the recovery or handling of SF 6 from high voltage (HV) switchgear, then you need to have passed a theoretical and practical examination in SF 6 handling and hold a certificate of competence issued by an accredited certification body.Phone: 01513394181

  • Development Sf6 Alternative Gases in Switchgears

    Nov 23, 2019An additional alternative approach is proposed to use air for insulation. The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing SF6 as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than SF6, and their boiling points are below 0 ˚C.

    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.
