Copper busbar is used in electrical power-sharing, busbars are usually made out of aluminum or copper, and they can conduct electricity to transmit power from the origin of electric power to the load. Insulators usually support them and conduct electricity within switchboards, substations or other electronic apparatus.

Some typical applications of these methods can be to form the interconnectedness of the incoming and outgoing electrical communication lines and transformers at an electrical substation; supplying vast amounts of amperes to the electrolytic process in an aluminum smelter by using large busbars and also interconnecting generators to the main transformers in a power plant.

The size of the copper busbar circumscribes its application and the amount of current that it can carry carefully. They can be tubular, solid or flat relying on the purpose and to serve different needs. A tubular busbar is hollow, and this configuration allows it to disperse heat more efficiently as it has a high surface area.

Hollow or flat plate solar collector are accepted in large current applications.

Also, the hollow segment of a busbar is generally stiffer as contrasted to a solid rod. Thus this allows a more significant measure between busbar support in outdoor switchyards. The shortest cross-sectional area of a busbar can be as little as 10mm2, but electrical substations would make aid of busbars with a diameter of more than 50 mm as they carry significant amounts of amperes. Aluminum smelters would make use of these large busbars to send tens of thousands of amperes to the electrochemical cells that produce aluminum from molten salts.

As they carry a large amount of electricity, it is essential to maintain the busbars with insulation to stop any accidents from happening whereby someone may inadvertently touch the bus bar. Insulation can either help the busbar or completely surround it. They can be prevented from accidental impact by putting the bus bars at a raised height so it would not be readily available or by a metal earth enclosure.

Some bus bars such as the earth bus bar can be bolted immediately into the housing chassis of their enclosure. This prevents rejected touch and also saves the bus bar from any damage it may incur when left exposed. There are numerous other ways that busbars can be connected to one another or the electrical apparatus with which they would be managed with such as by bolting, clamping or welding connections.

Switchgears, panelboards or busways regularly contain the busbars, and the distribution boards split the electrical supply into different circuits. Busways are a type of busbars that have a protective sheet and are long in shape. Also committed to as bus ducts, these methods allow the electricity to branch out to different circuits at any point besides its surface; unlike conventional bus bars that will permit branching of the main supply only at one location.

Above all are the important uses of copper bus bar which are very essential for us.
