Bare Copper Busbars Production Process Upgrade, Surface Treatment Technology Achieves Breakthroughs

In today's era of rapid development of digitalization and intelligence, the electrical industry has ushered in unprecedented development opportunities. The booming fields of new energy power generation and smart grid construction have put forward higher requirements for the performance and quality of bare copper busbars. As the "blood vessels" of the electrical connection system, BusBar Electrical undertakes the key tasks of transmitting large currents and distributing electrical energy. Their surface treatment process is directly related to electrical conductivity, corrosion resistance, and appearance quality, and has become the core technical focus of industry competition. Recently, there has been great news in the industry. The surface drawing process and nickel plating technology of Electrical Copper BusBars have both made breakthrough progress, injecting strong momentum into the high-quality development of the industry.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In terms of surface drawing process innovation, the scientific research team has conducted in-depth research on the principles of material mechanics and surface engineering and has launched a series of technical research and development for the problems of uneven texture and low efficiency in traditional drawing processes. Through repeated screening and optimization of wire drawing die materials, the use of new cemented carbide materials, combined with nano-level surface treatment technology, the surface finish of the die is improved several times, effectively reducing the friction with the Copper Solid Bus Bar surface, and reducing scratches and deformation during the wire drawing process.

 

At the same time, with the help of advanced sensors and automatic control systems, precise control of drawing speed, pressure, angle and other parameters is achieved, and the error range is controlled within ±0.01mm, ensuring that the surface of the BusBar Copper forms a uniform and delicate micron-level drawing pattern. This refined treatment not only significantly improves the appearance and texture of the product, but also increases the conductive contact area of ​​the copper busbar surface by about 15% by removing the surface oxide layer and impurities, reduces the contact resistance, and effectively alleviates the heating phenomenon during high current transmission. In addition, the lines formed by wire drawing also play the role of mechanical lock, enhance the adhesion of the subsequent nickel plating layer, and lay a solid foundation for overall performance improvement.

 

The breakthrough in nickel plating technology is also remarkable. With increasingly stringent environmental protection regulations, the industry has an urgent need for the green transformation of nickel plating processes. The new nickel plating process developed this time innovatively uses an organic amine system environmentally friendly plating solution. This plating solution is not only completely free of harmful substances such as cyanide and heavy metals but also has a self-purification function. Through a special combination of additives, it can automatically decompose organic impurities during the electroplating process, extending the service life of the plating solution by more than 3 times. In terms of equipment, pulse electroplating technology and a three-dimensional rotary electroplating device were introduced. The periodic change of the pulse current makes the deposition of nickel ions on the surface of the Bus Bar Electric more orderly, the formed coating crystals are fine and compact, and the porosity is reduced to 1/3 of the traditional process.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The three-dimensional rotary electroplating device breaks the limitations of traditional planar electroplating. By making the Electrical Copper BusBar move in multiple dimensions in the plating solution, it ensures that every corner of the complex-shaped busbar can obtain a uniform coating, especially the coverage effect of grooves, corners, and other parts is significantly improved. After testing, the bare copper busbar after nickel plating with the new process can withstand more than 1,000 hours in the salt spray test without corrosion. In the extreme temperature environment of -40℃ to 120℃, the bonding force between the plating layer and the copper busbar is still stable, which fully meets the application requirements of harsh scenarios such as offshore wind power and polar engineering.

 

The dual breakthroughs in the surface drawing process and nickel plating technology are the result of the deep integration of industry, academia, and research. Many universities, research institutes, and enterprises formed a joint research team, which took several years and thousands of experimental verifications and process optimizations to achieve the leap from theoretical innovation to industrial application. With the gradual promotion of these new technologies in the industry, it is expected that in the next 3-5 years, the overall quality and performance of Power Bar BusBar will be upgraded to a new level, and the production cost is expected to be reduced by 20%-30% while promoting the development of electrical equipment towards miniaturization and high efficiency.
