Bus duct industry: Technological innovation leads to new changes in power transmission

In modern power systems, bus ducts, as an efficient and safe power transmission device, are playing an increasingly important role. With the continuous advancement of technology and the growing demand from the market, the bus duct industry has also ushered in new opportunities and challenges.

Bus duct: A key equipment for power transmission

A bus duct is a power transmission system composed of metal plates (steel plates or aluminum plates) as the protective shell, conductive rails, insulating materials, and related accessories. It can be made in a plug-in type enclosed bus duct with a plug-in distribution box set at intervals, or a feeder type enclosed bus duct without a distribution box in the middle. Compared with traditional cables, bus ducts have the advantages of large current-carrying capacity, low voltage drop, high safety factor, and low construction and operation costs. Therefore, they are widely used in industrial buildings, commercial buildings, and residential buildings, etc.

Current industry development status: Market size continues to expand

In recent years, with the rapid economic development and the acceleration of urbanization in China, the demand for bus ducts has continued to grow. According to statistics, in 2023, the market demand for bus ducts in China reached 14.91 million meters, an increase of 690,000 meters compared to 2022; the market size was 71.195 billion yuan, a decrease of 1.242 billion yuan compared to 2022; the output reached 16.11 million meters, an increase of 660,000 meters compared to 2022. It is expected that by 2030, the market size of bus ducts in China will reach approximately 150 billion yuan, with a compound annual growth rate of about 12%.

From the perspective of market competition structure, there are numerous bus duct manufacturing enterprises in China, with a low industry concentration. The market entry threshold for low-end products is relatively low, and the competition among enterprises in the mid-to-low-end product market is very intense. With foreign large multinational groups also increasing their efforts to expand the Chinese market, the industry competition structure has become more complex.

Technological innovation achievements: Intelligence and greenness become development trends

In terms of technological innovation, the bus duct industry is moving towards intelligence and greenness. Intelligent bus duct products integrate technologies such as the Internet of Things and big data to achieve monitoring and optimization control of energy consumption; at the same time, the application of new materials and new processes will further improve the heat dissipation performance and fire safety of the products. For example, bus duct products using high thermal conductivity materials and halogen-free flame-retardant materials will gradually become the mainstream in the market.

In addition, some enterprises have also made innovations in the connection structure and heat dissipation design of bus ducts.

Application field expansion: Demand in emerging fields such as data centers and rail transit

With the acceleration of digitalization and urbanization， data centers and rail transit， as the main fields of new infrastructure construction， have a continuously rising construction demand. In this context， an efficient and safe power distribution system has become a key support， and bus ducts， with their modular design and high current-carrying capacity， are gradually replacing traditional cables and becoming the main power distribution components in these two scenarios.

In the data center field， bus ducts can quickly branch out power supply through plug-in boxes， reducing the space occupation of cable laying， and supporting hot-swappable maintenance， significantly reducing the risk of downtime. In the rail transit field， the fire resistance (such as a 950℃ fire resistance grade) and seismic design of bus ducts perfectly meet the safety standards of rail transit， making them the preferred solution for tunnels， platforms， and other scenarios.

Future Development Trends: Opportunities and Challenges Coexist

Looking ahead, the bus duct industry will face a situation where both opportunities and challenges coexist. On one hand, with the rapid development of building electrification, the construction of new energy vehicle charging stations, and smart grids, the demand for bus ducts will continue to expand. At the same time, the country's encouragement of energy conservation and green development has promoted the application of bus ducts in high-efficiency energy-saving projects. On the other hand, the industry also faces issues such as fluctuations in raw material prices, intensified market competition, and rapid technological updates.

To address these challenges, enterprises need to strengthen technological innovation, increase research and development investment, and continuously introduce new products and technologies; at the same time, they need to enhance brand building and market expansion to improve the market competitiveness of their products. Additionally, the industry needs to strengthen standard formulation and quality supervision to promote the healthy development of the industry.

In summary, the bus duct industry, as an important component of the power transmission field, is embracing new development opportunities. Driven by technological innovation and market demand, the bus duct industry will develop towards intelligence, greenness, and high performance, making greater contributions to the development of China's power industry.
