摘要：
The invention relates to the use of a mixture of a hydrofluoroolefin and a hydrofluorocarbon, optionally combined with another fluorinated gas, as an electrical insulation medium and/or an electric arc extinguishing medium in a medium-voltage electrical apparatus. The invention also relates to a medium- or high-voltage electrical apparatus in which such a mixture provides electrical insulation and/or electric arc extinguishing.
