Copper bus manufacturerDo you know what a copper busbar is, and do you know how to use a copper busbar? Today, the editor will use all of his talents to explain the detailed information about copper busbars to you.

Definition

Copper busbar is a high-current conductive product, suitable for electrical engineering such as high and low voltage electrical appliances, switch contacts, distribution equipment, and busway, and is also widely used in ultra-high current electrolysis and smelting projects such as metal smelting, electroplating, and chemical caustic soda production. Electrical copper busbars have the advantages of low resistivity and high flexibility.

Copper busbars, also known as copper motherboards, copper bus plates, or copper collector bars, grounding copper busbars, are made of copper and have cross-sections that are rectangular or chamfered (rounded) rectangles. Those made of aluminum are called aluminum busbars. In circuits, they function to conduct electricity and connect electrical equipment. The quality requirements for copper busbars follow the GB/T 5585.1-2005 standard.

Application

Due to copper's superior electrical conductivity compared to aluminum, copper busbars are widely used in electrical equipment, especially in complete switchgear assemblies; generally, the A, B, C, and N phase busbars, as well as the PE busbar in distribution cabinets, use copper busbars. In use, copper busbars are usually marked with phase letter codes or painted with phase-colored paint: the A phase busbar is marked 'yellow,' B phase 'green,' C phase 'red,' N phase 'light blue,' and the PE busbar is two-colored 'yellow-green.'

Copper busbar

Copper busbars are mainly used in primary circuits (larger current phase lines, neutral lines, and ground lines all use copper busbars). In electrical cabinets, connections of higher-current primary components all use copper busbars. For example, in a row of electrical cabinets, the connection between cabinets is the main busbar, and the main busbar distributes to the switchgear (isolating switches, circuit breakers, etc.) in each cabinet through the branch busbar. Copper busbars can be either tin-plated or bare copper. In electrical cabinets, the connection points of copper busbars generally require tin-plating and embossing or the application of conductive paste. Spare positions are often protected with heat shrink tubing, and some are coated with insulating paint. The primary consideration for using copper busbars is current carrying capacity, selecting appropriate busbars according to the current. The screws at connection points must be tightly fastened; otherwise, high current may cause the copper busbar to melt and burn.
