A tubular busbar is a hollow aluminium conductor profile that offers improved stiffness-to-weight and heat dissipation compared to solid bars. Tubular conductors are used where mechanical layout or thermal requirements favor a hollow cross-section. A transformer busbar is the rigid current-carrying link used to connect transformer windings, bushings, tap changers, terminals, and external power circuits. In practical engineering terms, the busbar in transformer assemblies must transfer high current with low impedance while fitting into a. Aluminium tubular busbar is a conductor used in power systems for transmitting large currents, made of high-purity aluminium or aluminium alloys, typically in a round hollow tube structure. In other words, Busbar is a junction where the incoming and outgoing feeders current meets i. it collects the power at single point. The current rating is calculated from the conductor cross-sectional area, material (copper or aluminium), and maximum. 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, transmission, or switching substations.
