Switchgear - Wikipedia that use carbon dioxide as the insulating and arc extinguishing medium work on the same principles as a sulfur hexafluoride (SF 6) breaker. Because SF 6 is a greenhouse gas more potent than CO 2, by switching from SF 6 to CO 2 it is possible to reduce the greenhouse gas emissions by 10 tons during the product lifecycle.
