Switchgear bus assembly having reduced power loss, material and temperature

Electrical switchgear comprising

• electrical switching equipment for a multi-phase electrical power distribution system,
• a supporting structure for a bus assembly for supplying electrical current to said switching equipment, and
• a plurality of spaced buses mounted on said supporting structure for connecting said switching equipment to respective phases of said multi-phase electrical power distribution system, each of said buses comprising
• a plurality of conductors in the form of elongated flat bars each of which has a pair of longitudinal flat side surfaces S and a pair of longitudinal edge surfaces LE extending along the length L of the flat bar, said plurality of conductors being arranged with at least one longitudinal edge surface LE of each conductor opposed to and spaced from a longitudinal edge surface LE of an adjacent conductor in that same bus, and with the side surfaces S of said plurality of elongated flat bars in each of said buses being substantially co-planar with the corresponding side surfaces of the other elongated flat bars in that same bus, and with the side surfaces S of the elongated flat bars in said buses opposing side surfaces of opposed flat bars in others of said buses.
• a plurality of electrically conductive connectors connecting said plurality of flat conductors in each bus together.
