66KV sf6 gas Purpose Prospect

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. They are very reliable and require less maintenance than air blast or oil breakers and
