  • An alternative to SF6 in electrical switchgear - EE Publishers

    For decades, the unique properties of sulfur hexafluoride (SF6) have made it popular as an insulation and switching medium for electrical switchgear. However, SF6 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 […]

    IEC standards have numbers in the range 60000–79999 and their titles take a form such as IEC 60417: Graphical symbols for use on equipment. Following the Dresden Agreement with CENELEC the numbers of older IEC standards were converted in 1997 by adding 60000, for example IEC 27 became IEC 60027. Standards of the 60000 series are also found preceded by EN to indicate that the IEC standard is also adopted by CENELEC as a European standard; for example IEC 60034 is also available as EN 60034.
