The paper is devoted to comparing the characteristics of SF6 and alternative environmentally friendly mixtures as insulating media in high-voltage circuit breakers. A comparative analysis of the dielectric and arc-extinguishing properties of gases was carried out according to the main physical characteristics the most promising mixture C4F7N/CO2 was chosen. An analytical calculation of insulation gaps and gas-dynamic characteristics for SF6 and its alternative has been performed. A numerical calculation of the electric fields for the live-tank circuit breaker VGT-110 with insulation media under study was carried out.
