Sulphur Hexafluoride (SF6) is a man-made greenhouse gas with a warming potential 23,000 times that of carbon-dioxide. Long-lived and potent, it is widely used as an effective insulator in electricity substation switch-gear and circuit breakers. Equipment containing SF6 is found at every network voltage. Also in wind-turbine circuit breakers.
