Description:

with the rapid development of the national economy in recent years, the output and consumption of copper busbar in China have been greatly increased. At the same time, the quality requirement of copper busbar has been continuously improved, and copper busbar is one of the main varieties of copper processed materials. Copper busbar has high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating, brazing, beautiful metal gloss and good formability. Electrical equipment has been widely used in the field of electric power. With the rapid development of national economy in recent years, the output and consumption of copper busbar in China have been greatly increased, and the quality requirements of copper busbar have also been raised. Quality influencing factors The surface quality of copper busbar can be divided into three main aspects: smooth surface, flat surface and surface defect. It is closely related to copper properties, production process, production management and production environment. 1. Influencing factors of smooth and clean surface of copper busbar Compared with other metals, copper has good corrosion resistance, but chemical changes still occur in high temperature, humidity, acid mist and other environments, resulting in surface discoloration. In the process of copper busbar production and storage and transportation, the existence of these unfavorable environmental conditions in varying degrees will affect the surface quality to some extent. 2, temperature In the atmospheric environment, copper oxidizes slowly at room temperature; when the temperature rises to 100 degrees Celsius, it begins to produce black copper oxide, which is proportional to the logarithm of time; when the temperature rises to 185 degrees Celsius, The oxidation rate increases significantly, and the oxidation rate increases more quickly when the temperature rises above 400 degrees Celsius, and the oxidation rate increases in parabola shape. 3, humidity In humid environment, due to the existence of water vapor, lead to copper busbar surface corrosion or oxidation. When the temperature is constant, the growth rate of oxide film increases with the increase of humidity. 4. Lubricant factor in drawing process The function of the process lubricant is to reduce friction, to ensure and improve the surface quality of the processed material, to prevent metal adhesion and welding on the die, and to cool the temperature. The surface quality of copper busbar is affected directly or indirectly by the lubricant, acid and water remaining on the surface of copper busbar during the process of copper busbar drawing. The better lubricant has good lubricity and the residual capacity on the surface of copper busbar is the source of discoloration or corrosion mark on the surface of copper busbar.

Characteristics:

1. The product surface is easy to produce burr, warp, Ma pit, easy to cause transformer winding insulation breakdown. 2. The resistivity and mechanical properties of the products are not uniform, it is difficult to meet the requirements of impedance matching of transformers and motors. 3. It is very difficult to produce copper busbar with wide thickness ratio greater than 10 and large sectional area. 4. If the surface of the bare wire is not properly treated, the lubricant residue on the flat wire affects the adhesion quality of the paint film. 5. According to different products need to be equipped with different specifications of the blank, raw material preparation complex. 6. Must have annealing process, large power consumption, long production cycle, large area of equipment. 7. Many production processes, long period, labor intensity, old equipment is difficult to do civilized production. 8. In the process of drawing the flat wire, the lubricant is heated and volatilized to produce irritating smell, which affects the health of the operator, and the lubricating fluid needs to be treated before it can be discharged, otherwise, it will cause environmental pollution.

Role:

copper busbar is an indispensable conductive material for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, and wires for distribution and installation. Copper busbar is one of the main varieties of copper processed materials. Copper busbar has high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating, brazing, beautiful metal gloss and good formability. Electrical equipment has been widely used in the field of electric power.
