  • Introduction to Gas Insulated Substations / Switchgears (GIS)

    As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas. Thereafter, they are taken to site for final assembly.

  • Gas-Insulated Substations - GIS - Electrical Engineering Portal

    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.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6 ) gas to cool and quench the arc on opening a circuit.
