FIELD: electricity.
SUBSTANCE: invention is related to a dielectric insulation medium, which contains fluorine ketone in gas condition, not necessarily with air or at least an air component as a carrier gas, which may be used for insulation of high-voltage equipment, in particular, distribution devices and transformers. The proposed insulation medium is characterised by the fact it contains fluorine ketone, having from 4 to 12 atoms of carbon, with a boiling point, at least - 5°C. Also the medium or high-voltage distribution device is proposed, in which the proposed insulation medium contained in the insulating space, is distributed in it in accordance with the temperature gradient.
EFFECT: increased extent of insulation protection of electric equipment without increase of gas and without negative effect of gas at environment.
