SF6 room Collection for HV MV

2014-10-22It clearly shown in these tables that the use of SF6 is predominant in HV: 90 % of the total SF6 volume in switchgear is for HV use, and only 10 % for MV. In MV, SF6 consumption concerns mainly RMU/switches and GIS, the part of MV CBs being almost negligeable. 3.3 EDF experience: 20 years of SF6 in MV
