In electrical power distribution, a busbar (also spelled bus bar, or sometimes as buss bar or bussbar, with the term bus being a contraction of the Latin omnibus, “for all”, is a metallic strip or bar (typically copper, brass or aluminium) that conducts electricity within a switchboard, distribution board, substation, battery bank, or other electrical apparatus.
Busbar is an electrical conductor that carries large current, especially one that is part of a power distribution system; typically a thick strip, or a tube. Busbars are used to carry substantial electric currents over relatively short distances; their greater surface area (compared to a wire of the same weight) reduces losses due to corona discharge.
Famous for its conductive qualities, copper has been the most popular material for busbars. The soaring popularity of copper in busbars could be attributed to its high threshold from damage from high temperatures which propels the life-span of the busbar.
With the slowdown in world economic growth, the Copper Busbar industry has also suffered a certain impact, but still maintained a relatively optimistic growth, the past four years.
For many business in the 21st century, energy efficiency has been the lynchpin and utilizing busbar systems can assist in reducing energy consumption. Given busbars are resilient and robust, it can withstand external weather conditions aptly, making them the prime candidate for being used on switchyards or electrical substations. There has been profound use of busbars in low voltage distribution, high current and control equipment. Further, application of busbars is extensively found in commercial building and other industries as plating cells and feeder systems.
Copper busbars and profiles play a crucial role in conducting electricity between the cells of a solar panel. Moreover, palpability of smart cities has augured well for busbars owing to prioritization of energy efficiency in electric infrastructure.
