Gas-Insulated Substations - GIS

Superior Dielectric Gas. 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.

ABB develops gas recycling technology that helps reduce

Purity of recycled SF6 gas using the newly developed technology is ~99.99 percent. This exceeds the purity that can be achieved using traditional methods and removes the need for costly and energy intensive gas destruction. Using recycled SF6 gas will help reduce carbon emissions and could result in a cost saving potential of up to 30 percent.

Myth About SF6 Gas In Electrical Equipment

3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
