SF6 Equipment Replacement units for High Speed Rail

SF6 Equipment Replacement units for High Speed Rail

SF6 has a number of advantages for use as an insulator. The dielectric strength of SF6 increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive.
