The Bare Copper Busbar Industry Has Ushered in New Opportunities For Both Quantity And Price Increases.

Technological innovation drives the upgrading of the industrial chain. Recently, the domestic copper processing industry has shown a significant growth trend. The market demand for bare copper busbars, which are key materials for power transmission, continues to heat up. According to industry data, with the rapid development of electrical equipment, communication facilities, and new energy fields, the application scenarios of bare copper busbars in low-voltage power transmission and distribution systems have continued to expand, driving the entire industrial chain into a stage of rising quantity and price.

As a core material for electrical conduction, Copper BusBars are widely used in power equipment, data centers, new energy vehicles, and other fields due to their advantages such as high conductivity and easy processing. Taking Shandong as an example, the region relies on rich copper resources and perfect industrial supporting facilities. The output of bare copper products accounts for about 10% of the national total, with an annual production capacity of more than 2 million tons. With the advancement of the "new infrastructure" and "dual carbon" goals, the market demand for high-purity bare copper busbars is growing at an average annual rate of 8%, especially in the field of high-end electrical equipment, which puts forward higher requirements for the purity and processing accuracy of copper materials.​

Industry data show that in the third quarter of 2024, domestic copper concentrate production increased by 42% year-on-year, driving the price of copper processed products to rise simultaneously. The financial report of a copper company shows that its net profit in the first three quarters increased by 24.33% year-on-year, mainly due to the increase in the volume and price of copper products. Among them, bare copper busbars, as high-value-added products, contributed significant profit growth. ​

Faced with the cost pressure of Electrical Bus Bar resources, companies in the industry are accelerating technological innovation and exploring new materials and processes. A composite material represented by copper-aluminum eutectic bars is emerging. Through solid-liquid casting and rolling composite technology, the copper-aluminum interface eutectic structure is achieved. While ensuring the conductive performance, the copper dosage is reduced by about 56%, which greatly reduces the weight of the product and optimizes the heat dissipation performance. This new material can be widely used in power, photovoltaic, rail transportation, and other fields. The cost is reduced by more than 40% compared with traditional pure copper busbars, becoming an important path to solve the problem of copper price fluctuations. ​

In terms of production technology, intelligent transformation has improved the manufacturing accuracy of bare copper busbars. By introducing digital twin technology, the company has achieved full process control from raw material smelting to finished product testing, and the product tolerance control capability has been improved from ±0.05mm to ±0.01mm, meeting the needs of high-end equipment for ultra-fine Electrical Copper BusBars. Data shows that the 0.05-0.08mm double zero-level ultra-fine bare copper conductor developed by a certain company has passed laboratory certification and is about to enter the large-scale mass production stage. ​

At present, the Copper Solid Bus Bar industry chain is upgrading from a single material supply to a system solution. Upstream copper companies have strengthened collaborative innovation with downstream electrical equipment manufacturers, and developed a large-section bare copper busbar integrated system to meet the high-density power transmission needs of data centers, supporting an increase in current carrying capacity of more than 20%. In the field of new energy vehicles, the integrated design of bare copper busbars and high-voltage wiring harnesses has promoted the development of on-board power systems towards lightweight and high reliability, and the use of copper materials in a single vehicle has increased by about 30% compared with traditional designs. ​

It is worth noting that the impact of environmental protection policies on Electrical Copper BusBar production is becoming increasingly prominent. By improving the smelting process, companies in the industry have reduced sulfur oxide emissions in the copper processing link by 60%, and at the same time built a waste copper recycling system to achieve a resource recycling rate of over 95%. Through the "copper-aluminum substitution" plan, a certain company has reduced the consumption of primary copper by more than 50,000 tons per year, which is equivalent to reducing carbon emissions by 120,000 tons. ​
