While power applications become smaller, faster and more complex, busbars remain the primary choice for electrical power distribution to carry and distribute electrical current.


busbars

In electric power distribution, a busbar (also known as bus bar or buss bar) is a metallic strip or bar, often housed inside switchgear, panel boards and busway enclosures for high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low voltage equipment in battery banks.

Busbars are generally uninsulated, and have sufficient stiffness to be supported in air by insulated pillars. These features allow sufficient cooling of the conductors, and the ability to tap in at various points without creating a new joint.

Chemical etching allows manufacturers of busbars to cost-effectively produce precise and intricate designs in various metals. The busbar’s material composition and cross-sectional size determine the maximum current it can safely carry.
