  • SF6 Gas handling | Zero emissions and maximum gas re-use

    Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas. SF 6 is among the six major gases subject to monitoring. Because of its high global warming potential, SF 6 is listed in the Kyoto protocol. Therefore, SF 6 has to be used in closed systems in order to avoid emissions.

  • Gas-Insulated Substations - GIS

    SF6 is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the SF6 will not condense into a liquid at the lowest temperatures the equipment experiences. SF6 has two to three times the insulating ability of air at the same pressure. SF6 is about 100 times better than air for interrupting arcs.
