The dielectric strength of sf 6 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 can operate at higher voltages effectively.

15 FAQs about sf6 gas Gas and sf 6 Breakers - WIKA blog

Why is SF 6 the preferred insulator for breakers and switchgears? SF 6 is extremely effective at quenching the arc generated when switching or opening electrical circuits. It also has very high thermal conductivity, especially at high temperatures, and, therefore, dissipates heat much better than air, nitrogen, helium, or other gases.
