A multiphase switchgear includes a switch panel, a vertical input housing module and a vertical switch housing module. The switch housing module and the input housing module are spaced apart from one another by a transverse housing module. The input housing module, the transverse housing module and the switch housing module form a first phase block. A plurality of phase blocks are located flush one behind the other in the direction of the transverse housing.

A three-position disconnector switch includes: an earthing contact; a power out contact; a power in contact; a first piston; and a second piston. In a connected switch position the first piston makes an electrical connection with the power out contact and the second piston makes an electrical connection with the power out contact and the power in contact. In a disconnected switch position the first piston makes an electrical connection with the power out contact and the second piston makes an electrical connection with the power out contact. In an earthed switch position the first piston makes an electrical connection with the earthing contact and with the power out contact and the second piston makes an electrical connection with the power out contact.

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.

A magnetic electrical switch apparatus includes: a switch assembly that includes: a switch body housing including a stationary contact; a shaft configured to move relative to the switch body housing, the shaft including: a moveable contact; and a first magnet; and a movable support member including a second magnet. The moveable contact and the first magnet are configured to move with the shaft. Moving the movable support member moves the second magnet relative to the first magnet, and a magnetic interaction between the second magnet and the first magnet moves the moveable contact relative to the stationary contact to thereby change a state of the switch assembly.
