  • SF6: Does its Impact Outweigh its Benefits? | TD World

    Gas insulated equipment is also more resistant to air contaminants and weather effects, increasing its longevity. While SF6 breaks down chemically when exposed to an arc, most of the altered material reforms or self-heals as SF6. As mentioned above, SF6 has come under fire as a potent greenhouse gas (GHG).

  • SF6 Circuit Breakers - Construction, Types and Working

    Advantages and Disadvantages of SF6 Gas In its pure state SF6 gas is colorless, odorless, tasteless and non-toxic. At room temperature and pressure, it is gaseous and has a density of 6.16 g/l, about five times the density of air. Since its critical temperature is 45.6°C it can be liquefied by compression and is normally transported as a liquid.
