    SF6-free switchgear is around 15-20% higher in cost, but this difference will diminish as production volumes increase. Moreover, SF6 switchgear is actually more costly if production, maintenance, and disposal costs are considered. Certain SF6-free technologies also do exist with lower maintenance costs than their SF6 cousins.
