The present invention relates to an insulating gas used for electrical insulation or arc extinguishing of an electrical device and an electrical device for insulating electricity using same. The insulating gas of the present invention, which can replace SF6 gas, consists of a mixed gas of trifluoromethyl trifluorovinyl ether (CF3OCFCF2) and a carrier gas. The insulating gas of the present invention has the characteristics of a low boiling point, high dielectric strength, low toxicity, and a low global warming potential (GWP = 1 or less), and thus can replace SF6. In addition, since the global warming potential is low while maintaining high insulating capacity and arc extinguishing capability, greenhouse gases can be reduced.
