Copper bus manufacturerTo explain the role of busbars in a circuit, do you know what a busbar is? A busbar is an electrical device, usually used for conducting electricity. Installing a busbar in a circuit not only protects the circuit but also allows large currents to flow in and out due to its low resistance. For more detailed information, please see below:

It serves to transmit current and connect electrical equipment in the circuit.

Copper busbars, also known as copper main bars or copper distribution bars, are made of copper and are long conductors with a rectangular or chamfered (rounded) rectangular cross-section (nowadays, rounded copper busbars are generally used to prevent corona discharge). They function to transmit current and connect electrical equipment in circuits. Copper busbars are widely used in electrical equipment, especially in complete power distribution devices;

In general, the U, V, W phase busbars and PE busbars in distribution cabinets are made of copper. In use, copper busbars are usually marked with phase letters or painted with phase colors: the U-phase busbar is painted yellow, the V-phase busbar green, the W-phase busbar red, and the PE busbar with alternating yellow and green. Copper busbars are mainly used in primary circuits (large-current phase lines, neutral lines, and ground lines all use copper busbars). Connections of large-current primary components in the cabinet are made with copper busbars. For example, in a row of cabinets, the main busbar connects the cabinets, and the main busbar branches to each cabinet's electrical switches (isolating switches, circuit breakers, etc.) as branch busbars. Copper busbars can be tin-plated or bare copper. In the cabinet, busbar connections are generally tin-plated and embossed or applied with conductive paste. Spare areas may be protected with heat-shrink tubing, and some are coated with insulating paint. The main consideration for using copper busbars is current-carrying capacity; busbars should be chosen according to current size. Screws at the connections must be tightened; otherwise, high currents could cause the busbar to burn and fuse.
