(Eaton Corporation, 2009) SF6, the most potent greenhouse gas with a Global Warming Potential (GWP) of 23.900 CO2 equivalents, is one of the substances that have been banned for almost all applications, except for high voltage and medium voltage switchgear. The reasoning for this exception
is that there would be no alternatives available. However, there is good news on the horizon:
Eaton has developed very compact and environmental friendly MV switchgear, called Xiria,
which is based on vacuum technology and solid insulation for voltages up to 24 kV. With this
green solution utilities can choose a sustainable alternative and therefore reduce the use and
emission of SF6 in their distribution networks. This green alternative – launched in 2002 – is now
finding a wide acceptance due to the fact that many utilities in Europe have decided to use this
SF6-free switchgear in their networks.
