A dielectric insulation medium. The insulation medium is characterized in that it comprises a fluoroketone having from 4 to 12 carbon atoms.

Dielectric insulation medium

An encapsulated switchgear that includes a housing defining, an insulating space, and an electrical active part arranged in the insulating space, the insulating space with an insulation medium. The switchgear is characterized in that the insulation medium with a dielectric compound having a boiling point of above &#x2212;5&#xb0; C.

Encapsulated switchgear

A dielectric insulation medium including a fluoroketone containing 5 carbon atoms, in a mixture with a dielectric insulation gas component different from the fluoroketone, in particular air or an air component, the dielectric insulation medium, in particular the dielectric insulation gas, having a non-linearly increased dielectric strength that is larger than a sum of dielectric strengths of the gas components of the dielectric insulation medium.

A dielectric insulation medium including a hydrofluoro monoether, the hydrofluoro monoether containing at least three carbon atoms. The insulation medium according has high insulation capabilities, in particular a high dielectric strength, and at the same time a low GWP. The invention further includes an insulation medium which is chemically and thermally stable also at temperatures above 140&#xb0; C., which is non-toxic or has a low toxicity level, and which in addition is non-corrosive and non-explosive.

An encapsulated switchgear that includes a housing defining, an insulating space, and an electrical active part arranged in the insulating space, the insulating space with an insulation medium. The switchgear is characterized in that the insulation medium with a dielectric compound having a boiling point of above &#x2212;25&#xb0; C.
