Busbar Trough Industry Development Trend Analysis: The Core Choice of Intelligent Power Distribution System

      In the field of industrial electricity and commercial building power distribution, the busbar trough, as a "vascular system" of power transmission, is undergoing a

synchronous upgrade of technological innovation and market demand. According to the latest data from the China Electrical Equipment Industry Association, the market size of China's busway in 2023 exceeded 18 billion yuan, of which the market share

of fireproof busway and intensive busway increased by 23% year-on-year, confirming the industry's clear trend of development in the direction of efficient safety.

First, busbar groove technology evolution route

    1. Material innovation to promote performance breakthrough

The third generation aluminum alloy conductor busbar launched by mainstream manufacturers in 2024 can reduce the weight by 30% while increasing the

conductivity by 15% compared with traditional copper conductor products. The

application of nano-level insulation coating makes the temperature resistance level of the product exceed 180℃, providing reliable guarantee for high-density power    consumption scenarios such as data centers.

   2. Intelligent monitoring system integration

Leading companies in the industry have embedded IoT sensors directly into the

busbar body to achieve real-time monitoring of key parameters such as temperature, current and insulation resistance through the cloud platform. In the application of a

certain brand of intelligent busway in a large commercial complex, the fault response time has been successfully reduced from 72 hours to 15 minutes.

   Ii. Analysis of market segment application scenarios

   1. Industrial field: The new energy automobile production line has a surge in

demand for large current busbars above 6300A, and the dustproof and waterproof grade is generally required to meet the IP68 standard

  2. Data center: Modular bus trough due to flexible expansion characteristics, in   the Tencent Qingyuan data center project to achieve a single loop of 2500kW power distribution capacity

  3. Rail transit: The new fire-resistant busway has passed BS6387 CWZ class

certification, replacing the traditional cable scheme in the subway emergency power supply system

Three, the six core indicators of the purchase of the busbar trough

 1. The matching degree of conductor cut-off quantity and temperature rise coefficient

 2. The compatibility of protection level (IP code) and installation environment

 3. Seismic performance (need to pass GB/T 2423.10 certification)

 4. Short-circuit withstand strength (Icw value)

 5. The number of hot swaps of the socket box

 6. Full life cycle maintenance cost accounting

   4. Industry standard and certification system

In 2024, the new GB7251.6 standard puts forward higher requirements for the  fire performance of bus bars, and the EU CE certification adds EMC electromagnetic compatibility test projects. It is recommended to focus on inspection when

purchasing:

• CCC compulsory certification certificate validity

• Third party test report (recommended to include salt spray test data)

• Thermal imaging simulation analysis report provided by the manufacturer

   5. Key technical points of installation and maintenance

1. Maintain 0.5-1.2m maintenance space when horizontal installation

2. A waterproof table must be set when crossing the floor vertically

3. A 2500V megohm meter should be used to test the insulation resistance every quarter

4. Check immediately if the temperature at the connection site is abnormal (exceeding the ambient temperature by 35 。C)

    With the in-depth promotion of the "double carbon" strategy, the busbar trough industry is accelerating the transformation in the direction of green energy saving.

The measured data of a central enterprise project show that the power distribution system using the new energy-saving busway can reduce the line loss by 28%

compared with the traditional scheme, and save more than 1.2 million yuan in electricity bills annually. In the next three years, with the continuous advancement of smart grid construction and old city renovation projects, the busway market will maintain an average annual compound growth rate of 9%, and technological innovation and service upgrading will become the key for enterprises to break through.
