Abstract: A gas insulated switchgear (GIS) system is provided including at least two separate modules including components of GIS, the at least two separate modules being independent of one another and configured to be assembled into the GIS system at a destination, wherein one or more of the at least two separate modules includes one of cabling and a solid insulated bus bar to connect the GIS system to an electrical power system at the destination. Related cabling modules are also provided.

Abstract: Modular switchgear systems are provided including at least two separate modules including components of switchgear. The at least two separate modules are independent of one another. One of the at least two separate modules is a stationary module and remaining ones of the at least two separate modules are removable such that the remaining ones of the at least two separate modules are configured to engage and/or disengage easily from the stationary module and an electrical power system. Related removable modules are also provided.

Abstract: A busbar connection includes first and second busbars each with a free end, and a shield device. The free ends of the busbars are directed towards each other and are in electrical contact with each other. The shield device envelopes the free ends of the busbars and is configured to steer the electrical field. The shield device includes a body of electrical conducting material. The body has two oppositely arranged contact surfaces in direct electrical contact with the free ends of the busbars. The body has a flange surrounding the contact surfaces and providing an upright edge around the contact surfaces.

Abstract: A terminal is provided for an electrical switchgear. The terminal includes: a housing arrangement including an electrically insulating material and having an inner surface defining a cavity; and a first terminal electrical contact contained in the housing arrangement for making an electrical connection with an electrical component insertable into the cavity. The first terminal electrical contact is located in a first recess formed in the inner surface, the first terminal electrical contact being flush with the inner surface.

Abstract: A switch arrangement for an electrical switchgear includes: a terminal arrangement including an insulating housing, the insulating housing including a first electrical contact and a second electrical contact which are spaced apart along an axial direction; and a breaker moveable along the axial direction in the housing to a first position. When the breaker is in the first position and closed it electrically connects the first electrical contact and the second electrical contact. The insulating housing is split into a plurality of separate sections along the axial direction. At least one of the electrical contacts is in a first section and at least another of the electrical contacts is in a second section.
