Laminated flexible busbar product definition and core advantages
Laminated copper busbar is an electrical connection component manufactured using a multi-layer composite structure, which occupies an important position in modern distribution and power transmission systems.
The Laminated copper bar has outstanding characteristics such as high safety and reliability, low impedance, low stray inductance, high current carrying capacity, and excellent heat dissipation. It can effectively replace traditional wiring and connection devices and has become an indispensable key component in high-end fields such as industrial equipment, power systems, national defense and military industry, and new energy. The overall application scenarios continue to expand, and the industry has significant development potential.
Core raw materials and industrial foundation support
Laminated flexible busbars are mainly composed of conductive materials, insulation materials, flame retardant materials, and adhesives, among which electrolytic copper is the most important conductive substrate, with a large usage and a relatively high proportion in product production costs. China is a major producer of electrolytic copper. After years of development, a stable and sufficient supply system has been formed, and the production has maintained a continuous growth trend. In 2024, the domestic electrolytic copper production has reached 13.644 million tons. The sufficient and mature upstream raw material supply system provides a solid industrial foundation for the large-scale and stable development of the Laminated bus bar for telecom industry.
Downstream application areas and market demand structure
Laminated inverter busbars have a wide range of applications, with industrial equipment, power systems, defense and military industries, and new energy being its four core demand areas. In the field of industrial equipment, the product can be used for equipment such as mining frequency converters and rail transit traction systems; In the field of power systems, it is mainly used in key links such as capacitor group parallel connection and IGBT module connection; In the field of national defense and military industry, with excellent environmental adaptability, it can adapt to special equipment such as armored vehicle rectifiers. Among them, the new energy sector is the largest demand side for Laminated busbar connectors, accounting for nearly 60% of the market share. It is mainly used in equipment such as photovoltaic inverters and energy storage converters. Driven by the rapid development of the new energy industry, market demand continues to rise.
Industry market size and development trend
With the continuous improvement of downstream industries, electricity, new energy and other fields, the market size of BusBar for power electronics in China has maintained a steady growth trend, and the overall market size will approach 100 billion yuan by 2024. Taking the new energy market as an example, the installed capacity of photovoltaic power generation in China will reach 890 million kilowatts in 2024, a year-on-year increase of 45%, directly driving the demand for related power devices and connecting components. In the future, with the continuous expansion of the new energy industry and the upgrading of power equipment, the market space for Laminated bus bar for industrial will further expand, and the industry as a whole will upgrade towards high quality, high performance, and high reliability. The market share of high-end products is expected to continue to increase.
