A copper busbar, also known as copper busbar or copper busbar, is a long conductor made of copper material with a rectangular or chamfered (rounded) cross-section (nowadays, a rounded copper busbar is generally used to avoid sharp discharge). It plays a role in transporting current and connecting electrical equipment in circuits. Copper bars have been widely used in electrical equipment, especially in complete power distribution systems. Generally, copper bars are used for the U, V, and W phase busbars and PE busbars in the distribution cabinet. Copper bars are generally marked with colored letters or coated with colored paint during use. U-shaped copper bars are coated with “yellow” color, V-phase copper bars are coated with “green” color, W-phase copper bars are coated with “red” color, and PE busbar copper bars are coated with “yellow-green alternating” dual color.
Copper bar
Copper bar is a high current conductive product, suitable for electrical engineering such as high and low voltage appliances, switch contacts, distribution equipment, bus ducts, etc. It is also widely used in metal smelting, electroplating, chemical caustic soda and other ultra-high current electrolytic smelting projects. Electrical copper bars have the advantages of low resistivity and high bendability.
Copper busbar, also known as copper busbar, copper busbar or copper busbar, grounding copper busbar, is a long conductor made of copper material with a rectangular or chamfered (rounded) rectangular cross-section. Made of aluminum material, it is called an aluminum busbar and plays a role in transmitting current and connecting electrical equipment in circuits. The quality requirements for copper busbars are in accordance with the GB/T 5585.1-2005 standard.
Due to its superior conductivity compared to aluminum, copper bars have been widely used in electrical equipment, especially in complete power distribution systems. Generally, copper bars are used for the A, B, C, and N-phase busbars and PE busbars in the distribution cabinet. Copper bars are generally marked with colored letters or coated with colored paint during use. The A-phase copper bar is marked with “yellow” color, the B-phase is marked with “green” color, the C-phase is marked with “red” color, the N-phase is marked with “light blue” color, and the PE busbar is marked with “yellow-green” dual color.
Copper bars are mainly used on primary lines (high current phase lines, neutral lines, and ground lines all use copper bars).Copper bars are used to connect primary components with high current on electrical cabinets. For example, a row of electrical cabinets is connected to the main busbar between cabinets, and the main busbar is divided into branch busbars for each electrical cabinet’s switch (isolating switch, circuit breaker, etc.). Copper bars come in both tin-plated and bare forms.In electrical cabinets, the connections between copper bars are usually treated with tin plating, embossing, or conductive paste. There are heating shrink tubing protections in the vacant areas, and some are coated with insulating paint. The main consideration when using copper bars is the current carrying capacity. Choose the appropriate copper bar according to the current size, and the screws at the connection must be tightened. Otherwise, there is a possibility of melting the copper bar when the current is high.
