SWITCHGEAR AND Sulfr hexafluoride GAS - Gob

metal-enclosed switchgear, where the Sulfr hexafluoride gas provide the main insulation of the equipment. Vacuum or Sulfr hexafluoride interrupters can be used. A particular case, broadly used in the public secondary network, is the Sulfr hexafluoride insulated Ring Main Unit (RMU). In this type of equipment switching devices are contained in a single enclosure, where the sf 6 gas ensures simultaneously two tasks: general insulation and arc-quenching.Get price

Blog | Ending the use of SF₆ in power grids | Eaton
