SF6 Consolidation units for gis

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

    A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what SF6 can do in centimeters.
