FIELD: chemistry.
SUBSTANCE: invention relates to use of mixture comprising decafluoro-2-methylbutan-3-on and a carrier gas or dilution gas as a medium for electrical insulation and/or for extinction of electric arcs in a medium- or high-voltage electrical devices. It also relates to a medium- or high-voltage electrical device in which electrical insulation and/or extinction of electric arcs is/are implemented by a mixture comprising decafluoro-2-methylbutan-3-on and a carrier gas or dilution gas. Applications: electrical transformers, gas-insulated lines for transporting or distributing electricity, set of busbars, electrical connection/disconnection devices (circuit breakers, switches, switch-fuse sets, disconnectors, earthing switches, contactors, etc.).
EFFECT: technical result is creation of a mixture with satisfactory electrical insulation properties and electric arc extinction properties with low or zero impact on the environment.
