Jul 01, 2020Just one kilogram of SF 6 released into the atmosphere is equivalent to 23,500 kg of CO 2 —making it by far the most potent greenhouse gas. SF 6 sticks around too, staying in the atmosphere for more than 3,200 years. There’s a reason SF 6 is one of only seven greenhouse gases listed in the Kyoto Protocol and the Hazardous Substances Data Bank

The Siemens range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept.

SF6 gas is listed as an extremely harmful GHG by the Intergovernmental Panel on Climate Change (IPCC). Presently, no nearest alternative can work as efficiently as SF6 gas. Hence, increased procurement cost, coupled with stringent policies against SF6 gas, will restrict the growth of this market during the projected period.

In gas insulated medium voltage switchgear, sulphur hexafluoride (SF6) gas is used for insulation and vacuum technology is used for circuit breaking. Only SF6 is used both insulation and for interruption medium in the gas insulated switchgear system for the applications above 72.5 KV, as vacuum technology is limited to low voltage applications.
