SF 6 in electrical equipment of 1 kV to 52 kV (medium-voltage)· PDF fileSF 6 in medium-voltage equipment contributed only to 0,01% to total EU-15 greenhouse gas emissions in 2002. This proven low impact of SF 6 emissions from medium-voltage switchgear amounts to a fraction of the overall emissions and only is a very minor concern. Therefore, there is no added value in introducing stricter regulatory constraints.[email protected]
