Overview of Copper Busbars
The copper busbar produced by pure copper is called the copper busbar.It is named for its purple color. Copper busbar is a high-current conductive product, which is suitable for electrical engineering such as high and low-voltage electrical appliances, switch contacts, power distribution equipment, busways, etc. It can simplify the design of power distribution equipment and busbar systems in substations, reduce the installation area, and improve the safety and reliability of the power supply system.
Advantage of Copper Busbars
Red copper busbar products have high copper content, low oxygen content, compact and uniform structure, low resistivity, high conductivity, precise size, and excellent mechanical properties. The copper bar has excellent electrical conductivity and production and processing characteristics, ensuring high current flow. High precision, suitable for large and medium-sized fine mechanical equipment. The parts of the copper bar have stronger corrosion resistance and a longer service life. The surface of the copper row is smooth, wear-resistant, corrosion-resistant, and easy to process. Products in specified lengths can be provided according to your needs.
Production of Copper Busbars
The production process of red copper busbar is roughly as follows:
Prepare copper ingot.
The copper ingot is heated to the melting point, poured into a concave copper mold, and extruded and deformed into a copper bus bar embryo.
The copper busbar is pickled to remove surface oxides.
After stretching deformation and finishing treatment, the copper busbar gradually becomes thinner and longer.
Coiled into round or other shapes.
After quality inspection, the red copper busbar can be put into use.

The characteristics of each grade material and the fields of use
Item | Characteristic | Fields of application |
C11000 | It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazing. Impurities containing reduced electrical and thermal conductivity are small, and trace amounts of oxygen have little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease", and it is not easy to process (annealing, welding, etc.) and use in a high temperature (such as 370 °C) reducing atmosphere. | Used in electrical, thermally conductive and corrosion-resistant equipment. Such as: wires, cables, conductive screws, detonators for blasting, chemical evaporators, storage devices and various pipelines |
C10200、C10300 | It has high purity, excellent electrical and thermal conductivity, no "hydrogen disease" or very little "ammonia disease" (no hydrogen embrittlement), good processing performance and welding, corrosion resistance and cold resistance | It is mainly used as electric vacuum instrumentation devices, various hardware products, lamps, pipe fittings, zippers, plaques, rivets, springs, settlement filters, etc |
C12000 | Its welding performance and cold bending performance are good, generally no "hydrogen disease" tendency, can be processed and used in a reducing atmosphere, but not suitable for processing and use in an oxidizing atmosphere. The residual phosphorus content of C12000 is less than that of C12200, so its electrical and thermal conductivity is higher than that of C12200. | It is mainly used in pipes, but can also be supplied as plates, strips or rods and wires. Used as gasoline or gas transmission pipes, drain pipes, condensation pipes, mine pipes, condensers, evaporators, heat exchangers, train car parts. |

Q1
What is the difference between copper busbar and cable?
Answer: Copper busbars are exposed conductive materials, mainly used for the direct transmission and distribution of current, while cables are composite structures composed of conductors, insulation layers and protective layers, used to transmit electrical energy or signals. Copper busbars have higher conductivity and are suitable for the transmission of large currents, while cables are suitable for the transmission of smaller currents.
Q2
How to install and maintain copper busbars?
Answer: The installation of copper busbars requires professional electrical engineers or technicians. During the installation process, it is necessary to ensure that the busbars are tightly connected, in good contact, and take appropriate fixing measures. In terms of maintenance, it is necessary to regularly check the connection status and surface condition of the busbar, remove dirt and oxides in time, and maintain its good conductive properties.
Q3
Can copper busbars be welded?
Answer: Yes, copper busbars can be soldered. Common welding methods include brazing, TIG welding, etc. During the welding process, it is necessary to select appropriate welding materials, control welding temperature and speed and other factors to ensure welding quality and strength.
Q4
What is the difference between copper busbar and aluminum busbar?
Answer: Copper busbars and aluminum busbars differ in conductive properties, stability, corrosion resistance, etc. Copper busbars have high conductivity and good stability and are suitable for power systems with high requirements; while aluminum busbars have lighter weight and lower cost and are suitable for some occasions that do not require high conductive performance.
Q5
How to surface treat copper busbars?
Answer: The surface treatment of copper busbars can be carried out by a variety of methods according to needs, such as polishing, sandblasting, oxidation, electroplating, etc. These treatment methods can change the appearance and performance of copper busbars, improve their corrosion resistance, aesthetics, etc.
