Switches are factory filled with non-toxic, non-flammable, high dielectric SF6 gas insulation. SF6 quality and stability are maintained by use of totally sealed tank construction, an internal purifying absorbent and the extremely fast Arc Whipper interrupter. A color coded, field replaceable pressure gauge and self-sealing fill valve allow monitoring and addition of SF6 as necessary.

Get PriceSulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture. SF6 easily hydrolyses into fluorinated compounds in water (thionyl fluoride and hydrogen fluoride) that are extremely toxic and corrosive substances. And it is part of the six gases responsible of greenhouse effects covered by the Kyoto Protocol (one kilogram exhausted in the air equals around 23,000 kg of carbon dioxide (CO2) on the long run).
