SF6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and cooling medium.
Science: in general, any increase in the speed or rate at which some process occur; in technical use acceleration and speed are not synonymous.Mechanics: the vector representing the rate of change in velocity vector over time.It is expressed in meters (or feet) per second per second, and it involves an increase or decrease in speed and a change in direction.
