Ban on climate-damaging gaz sf6 possible in medium-voltage systems. Medium-voltage power transmission and distribution systems currently contain sulphur hexafluoride (sf6 gas), which is 23,500 times more damaging to the climate than carbon dioxide. By 1 July 2020, the EU Commission is required to assess whether a ban on new secondary medium-voltage
