In electric power distribution, a bus duct (also called busway) typically uses sheet metal, welded metal [1] or cast resin to contain and isolate copper or aluminium busbars for the purpose of conducting a substantial current of electricity. It is an alternative means of conducting electricity to power cables or cable bus.
In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks .
Currently, the isolated-phase bus world record current is 52,000 A, for bus manufactured by Alstom Power (since 2015 General Electric Power) and installed at the Civaux Nuclear Power Plant, in 1997. Other types of bus are: Metal-enclosed segregated phase bus; Low and high impedance bus duct; Bare flat or tubular bus bars; Non-segregated Phase ...
Enclosure comparison with normal wiring & with busbar system. Electrical busbar systems [1] (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar.

The $1 billion in annual revenue from the tolls would help fund critical and long overdue improvements to the city’s bus and subway systems, which run 24/7 and move more than 4.5 million people ...
Busbars may be aluminum tubing 3–6 inches (76–152 mm) thick, or else wires (strain bus). [ 33 ] Outdoor, above-ground substation structures include wood pole, lattice metal tower, and tubular metal structures, although other variants are available.
