Innovation in Refractory Busbar Technology for Building Safety Upgrading: Industry Trends And Future Prospects

      In recent years, with the rapid development of urban high-rise buildings, rail transit, data centers and other fields, the safety of power transmission systems has become the core issue of concern in the industry. In this context, fire-resistant bus as a key power transmission equipment, with its excellent fire performance and stability, gradually become the first choice for building electrical design.

    Core value and application scenario of refractory bus bar

    Refractory bus is a power transmission device designed for extreme environments, its core advantage is the ability to maintain a stable power supply in high temperature environments. Through the use of special refractory materials (such as ceramic silicone rubber, mica tape, etc.) and multi-layer protective structures, the refractory bus can continue to operate for 1 to 4 hours in a fire, and gain valuable time for personnel evacuation and fire rescue. At present, the technology has been widely used in hospitals, airports, subways, chemical parks and other scenarios with high security requirements.

   The iterative direction of busbar groove technology

   As the core carrier of busbar system, the design of busbar groove directly affects the efficiency and safety of power transmission. The current industry technology iteration focuses on three major directions:

1. Fire performance improvement: reduce fire risk by optimizing insulation material and structural design;

2. Intelligent monitoring: integrated temperature and current sensors to achieve real-time monitoring and early warning of busway operating status;

3. Modular installation: standardized interface design is adopted to shorten the construction period and reduce maintenance costs.

   Market trend and policy drive

   According to the White Paper on China's Power Equipment Industry in 2023, the annual growth rate of the refractory bus market is 12%, of which the demand for public buildings and industrial fields accounts for more than 60%. At the policy level, the newly revised "Code for Fire Protection in Building Design" (GB50016-2023) clearly requires that the busbar system with a fire rating of not less than 120 minutes must be used in densely populated places, further promoting the standardization process of the industry.

   Future challenges and coping strategies

   Despite the broad market prospects, the industry still faces challenges such as high technical barriers and high cost pressure. In this regard, Sichuan Shuteng Bus Co., Ltd. and other industry-related enterprises are accelerating technological breakthroughs through industry-university-research cooperation, such as the development of low-smoke halogen-free refractory materials and optimization of thermal structure design. At the same time, promoting the integration of "busbar groove + Internet of Things" will become the core path to enhance the added value of products.
