SF6 insulated station EMT

SF6 insulated station EMT

Sep 15, 2019 · At minimum functional SF6 pressure, the following conditions are tested: phase-to-ground, phase to-phase (in the case of three phases in one enclosure design), and across open switching devices. Successfully withstanding the one minute withstand level without a disruptive discharge is the main criteria to mark that the test passed successfully.

  • 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.
