What is the disc-type copper busbar?
The disc-type copper busbar is a round pie-shaped copper busbar with a hollow in the middle. Using copper as raw material, a material with high conductivity and high strength is obtained through a series of processes. The thickness is large, and it is often used in the manufacture of various electrical facilities, such as switchgear, busbars, circuit breakers, and other high and low-voltage electrical facilities, as well as wind power generation, hydropower, nuclear power units, and other power generation facilities.
What are the advantages of disc-type copper busbars?
Disc-type copper busbar has a smooth surface without wire drawing, precise size, high mechanical properties, good electrical conductivity, thermal conductivity, beautiful and beautiful metallic luster and good formability, high copper content, low oxygen content, compact structure, supply length is free, supply by weight. It has a hard texture and has the high strength of ordinary metals. It is not easy to corrode, has high-temperature resistance and high-pressure resistance, and can be used in a variety of environments. Withstands extreme temperatures and has a wide range of applications from -196°C to 250°C. Safe and reliable to use, good toughness and high ductility, with excellent vibration resistance, impact resistance, and frost heave resistance. Good for health, copper has stable chemical properties and is not easy to age.
How do you produce disc-type copper busbars?
The production of disc-type copper busbars mainly includes the following steps:
The copper busbar is extruded and shaped for surface redox treatment.
The copper busbar is heat-treated through a high-temperature furnace to achieve the softening effect.
Continuous stretching using a special stretching machine so that the copper busbar gradually becomes thinner and longer.
Surface treatment of copper busbar, including removing oxidized layer, cleaning, and painting.
Curl the copper busbar into round or other shapes.
Conduct quality inspection, including size, surface, material, and so on.
What is the application of disc-type copper busbars?

| 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. |
