Switchgear Solutions - Power Line Magazine· This kind of switchgear uses vacuum as the arc quenching medium. As vacuum has the highest insulating strength, a vacuum switchgear has a much superior arc quenching property than any other medium. Hence, as soon the arc is produced in vacuum, it is extinguished pertaining to the fast recovery of dielectric strength in vacuum.
