Abstract: In an embodiment, the present invention provides a gas insulated switchgear for medium- or high-voltage use, including: a closed housing of a switchgear compartment having insulating gases or fluids. The insulation gas includes sulfurhexaflouride (SF6). Constructive features of the switchgear are designed such that they are overperformed for the use of sulfurhexaflouride (SF6), but already sufficiently performed for the use of eco efficient insulation gas with a mixture of up to 20% fluoroketone C5F10O and air or oxygen and carbondioxide. A later retrofit or adaption to a switchgear, filled with eco-efficient insulation gas, only needs the aforesaid gas exchange, without exchanging constructive parts of the switchgear.

Abstract: A medium voltage load break switch includes a main contact and a knife. The knife is rotatable about a pivot point to connect to and be in contact with the main contact and to rotate about the pivot point to disconnect from and be spaced from the main contact. The load break switch also comprises a vacuum interrupter that has a fixed contact and a moveable contact. A lever rotates about a rotation point and a shaft of the moveable contact is aligned along an axis of the vacuum interrupter, and the shaft of the moveable contact is linked to the lever.

Abstract: In an embodiment, the present invention provides a medium voltage circuit breaker in high pressure subsea environment, including: a vacuum circuit breaker; and a drive in a pressure tight housing. For an electrical three-phase arrangement, one vacuum circuit breaker per phase is in arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which all the three drives for the three vacuum circuit breaker are arranged. The three pole housings and the common base compartment are attached such that they form commonly a pressure tight compartment.
