China's busbar trunking industry

The intelligent revolution experienced by China's busbar trunking industry in the past decade is essentially a systematic transition from passive transmission equipment to active energy nodes. The industry takes the 'sandwich' structure bus duct as the physical base, integrates high-precision sensor networks (millisecond level acquisition of current, temperature and voltage), edge computing and the Internet of Things (IoT) platform, and constructs a closed-loop system of 'perception early warning decision-making'. The accuracy rate of fault early warning is more than 99.5%, and the operation and maintenance cost is reduced by 40%. Leading companies such as Gaobiao Electric, Chint, and Weiteng Electric have built digital twin intelligent factories, achieving flexible production lines and customized delivery, shortening production cycles by more than 30%, and supporting 'one production line, thousands of specifications'. The product deeply integrates BIM and smart building systems, and connects to the dynamic environment platform through protocols such as Modbus and BACnet, achieving full scenario linkage with key facilities such as data centers, hospitals, and subways. The fire resistance performance has broken through to 950 ℃ for continuous power supply for 240 minutes, and the protection level has reached IP67, completely reshaping the safety standards for high-density electrical scenarios. By 2026, the market size of intelligent busbar trunking will exceed 28 billion yuan, accounting for over 55%, with a year-on-year increase of 19.4% in export value. Technical standards are shifting from 'following national standards' to 'leading globally'.
