switches - How is oil-filled switchgear possible ... another level switching high voltage beams or e-beams use a gas insulator called Chlorine HexaFluoride ? (CLF6) as an gas insulator. But if the gas arcs fro high voltage e-beam and contaminant it turns in Mustard Gas, even more toxic than toxic PCB's. Literature is scares on this for a reason as not to frighten the public.
