Copper is conductive, and copper wires are often used in power distribution systems. Copper busbars are used similarly; their function is to carry current. They can be seen in many distribution cabinets, high-voltage electrical equipment, and some large power devices. They can also be used in metal smelting. Copper's properties are superior to aluminum, so its market value has always been relatively high. Today, I will take you to specifically understand the uses of copper busbars.

Copper busbar, also known as copper main bar or copper distribution bar, is made of copper and is a long conductor with a rectangular or chamfered (rounded corner) rectangular cross-section (nowadays, rounded corner copper busbars are generally used to avoid corona discharge). In a circuit, it functions to carry current and connect electrical equipment.

Copper busbars are widely used in electrical equipment, especially in complete distribution devices; generally, the U, V, W phase busbars and PE busbars in distribution cabinets are made of copper busbars. In use, copper busbars are generally marked with phase letters or coated with phase-colored paint. The U-phase copper busbar is coated in 'yellow', the V-phase copper busbar is coated in 'green', the W-phase copper busbar is coated in 'red', and the PE busbar copper busbar is coated in 'yellow-green' two colors.

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

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.

Copper is also very common in our daily life, and even now many people still wear copper ornaments. Copper seems to be one of the metals closest to us. We believe that its uses will increase in future development. If you need copper busbars, you are welcome to contact us at Yixing Xinda Science & Technology New Energy Co., Ltd.
