Abstract
A switchgear assembly has a contact gap and an insulating material nozzle. The insulating material nozzle at least partly encloses the contact gap. A nozzle channel for the insulating material nozzle opens with a outlet opening in a hot gas space. A deflector element is disposed within the hot gas space which defines a deflector channel. The deflector channel has a segment which has an expanding cross-section in the stream direction of a switching gas in the hot gas space.
