Procurement Volume Of Dedicated Busbar Trunking Systems For Data Centers Keeps Surging

As the implementation of the East Data, West Computing project and the accelerated construction of AI computing centers advance, China's data center industry has entered a phase of rapid expansion. Surging demand for power distribution in high-density and eco-friendly computer rooms has driven a substantial increase in orders across the busbar trunking sector. Recent procurement statistics reveal that purchases of busbar trunking systems for data center applications have risen sharply year-on-year, with demand becoming diversified and tiered. Three major product categories - compact AC busbar trunking, compact DC busbar trunking and intelligent busbars - are all seeing robust order growth.

Traditional general-purpose compact AC busbar trunking remains the top choice for high and low voltage main power distribution in large-scale data centers. It is primarily deployed for high-current power transmission between transformers and low-voltage switchgear as well as main incoming power circuits of computer rooms. Featuring a compact and densely insulated structure, this product delivers excellent heat dissipation and high current-carrying capacity. Capable of continuous power transmission at several thousand amperes, it ensures stable basic power supply for computer rooms and maintains a steady procurement share in colocation and traditional cloud computing data center projects.

With the widespread adoption of energy-saving high-voltage DC power distribution solutions, compact DC busbar trunking has recorded the fastest procurement growth. Many new-generation AI computing rooms adopt a high-voltage DC architecture, which reduces line power loss and optimizes the Power Usage Effectiveness (PUE) compared with AC systems. Optimized for DC electric arcs and creepage risks, DC busbar trunking is engineered with enhanced insulation and arc-extinguishing structures. It is widely used for power supply to energy storage battery packs, DC column cabinets and GPU computing clusters, and has become standard equipment for newly built green computing hubs.

Track-type busbar trunking, also known as miniature track busbars, has emerged as the mainstream solution for power distribution to end cabinets in computer rooms, thanks to its advantages of flexible capacity expansion, quick connection and reusable assembly. Its modular track structure allows additional plug-in units for cabinets to be installed without power cuts. It features a short construction cycle and a smaller footprint, making it ideal for high-density AI server clusters. Demand for this product has grown notably in power distribution renovation projects for existing computer rooms.

Industry research indicates that the market size of busbar trunking for domestic data centers will exceed 10 billion RMB in 2026, and the simultaneous growth of the three product categories will become a long-term trend. Rising computing density and the implementation of green and low-carbon policies will keep driving technological upgrades for busbar trunking products. Manufacturers in the industry are continuously enriching their full product portfolio and improving standardized manufacturing processes for AC busbars, DC busbars and track-type busbars. They strive to deliver one-stop power distribution solutions for super-large data centers and AI computing rooms, so as to capture the development opportunities brought by digital infrastructure construction.
