In , a busbar (also bus bar) is a metallic strip or bar, typically housed inside,, and for local high current power distribution, transmission, or switching substations. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in. They are generally uninsulated, and have sufficient stiffness to be supported in air by insulated pillars. Those features allow sufficient cooling of the conductors, and the ability to tap in at various points without having to create a new joint. The busbar's material composition and cross-sectional size determine the maximum current it can safely carry. Busbars can have a cross-sectional area of as little as 10 square millimetres (0.016 sq in), but may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars. use very large busbars to carry tens of thousands of to the that from molten. Busbars are produced in a variety of shapes, including flat strips, solid bars and rods, and are typically composed of, or as solid or hollow tubes. Some of these shapes allow to dissipate more efficiently due to their high to area ratio. The makes busbars more than about 8 millimetres (0.31 in) thickness inefficient, so hollow or flat shapes are prevalent in higher-current applications. A hollow section also has higher than a solid rod of equivalent current-carrying capacity, which allows a greater span between busbar supports in outdoor. A busbar must be sufficiently rigid to support its own weight, and force. • – Data transfer channel connecting parts of a computer• – Low resistance electrical conductor for high current transmission and distribution• – Modular approach to electrical wiring• – Short length of conductor• – Short length of conductor • Elmore, Walter A.
