sf 6 Gas Transformers | Transmission Distribution Systems

ToshibaGas Insulated Transformer (GIT) is the most technologically advanced solution for hydro-power and underground substations, densely populated cities, mission critical substations, and offshore substations. Toshiba GITs are insulated with SF 6 gas rather than traditionally hazardous oil which risks fire, explosions, and contaminating leaks.

sf6 gas gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (gaz sf6) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. Sulfr hexafluoride is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.
