Claims28
A dielectric insulation medium comprising an insulation gas, said insulation gas comprising at operational conditions a fluoroketone having from 4 to 12 carbon atoms, characterized in that the fluoroketone has a boiling point of at least −5° C. at ambient pressure.
A dielectric insulation medium comprising an insulation gas, said insulation gas comprising at operational conditions a fluoroketone having from 4 to 12 carbon atoms and having the general structure
- R1—CO—R2
- wherein R1 and R2 are at least partially fluorinated chains, said chains being independently from each other linear or branched and having from 1 to 10 carbon atoms.
A dielectric insulation medium comprising an insulation gas, said insulation gas comprising at operational conditions a fluoroketone, characterized in that the fluoroketone has 6 carbon atoms.
