    For example:- phase-to-ground clearance for 132 kV systems is around 1200 mm in air, compared to 80 mm in SF6 gas at 4.0 bar(g).This gives a direct reduction in dimensions of the high-voltage equipment by 15 times. Consequently, the size of SF6 insulated equipment is around 6% that of air insulated equipment for this voltage class (132kV).
