SF6-free – Stromnetz Berlin places climate-friendly ... with Siemens, Stromnetz Berlin today commissioned a switchgear installation in a medium-voltage (10 kV) compact station in Siemensstadt that operates without the global warming gas sulphur hexafluoride (SF6). To eliminate the need for SF6, which is a global warming gas, the 8DJH 12 blue GIS switchgear uses clean air as an insulating gas.

Switchgear - Wikipedia an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.

SF6 (GIS) gas insulated substation Manufacturer in China ... SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for ...
