With the explosive growth in demand for AI computing power, the construction of AI data centers (AIDC) has entered the fast lane. In this industrial transformation, Changzhou Guanghui Transformer Co., Ltd., an enterprise in Changzhou High tech Zone, is becoming a highly regarded force in the AIDC wave with its profound manufacturing heritage and forward-looking strategic layout.
Entering April, the production workshop of Guanghui Transformer is busy, and the traditional peak production season has arrived as scheduled. All production lines are operating at full capacity to ensure the delivery of transformer orders. A production line requires about 10 processes, but now only 2 personnel are needed to operate efficiently, "said Wang Junqian, the company's general manager, standing next to the automated production line with a tone of pride. Behind this change is the result of enterprises continuously investing funds to promote intelligent transformation. In recent years, Guanghui Transformer has deeply integrated traditional manufacturing with intelligent manufacturing, not only greatly improving production efficiency, but also achieving sustained growth in per capita output value. In 2025, the company's sales revenue will be about 220 million yuan, and the steady and progressive development trend has laid a solid foundation for welcoming the AIDC trend.
About Guanghui Transformer
Founded in the late 1970s, we have been committed to the main business of transformers for over 40 years, completing two key transformations from extensive production to high-quality manufacturing, and from traditional manufacturing to intelligent green manufacturing. Changzhou is vigorously expanding its AIDC industry, which has opened up new growth opportunities for local equipment manufacturing enterprises. We have been deeply involved in the transformer field for more than 40 years, and all our technological accumulation and capacity upgrades are aimed at accurately meeting the needs of emerging industries. ”Wang Junjuan stated that relying on the strong equipment manufacturing industry foundation in Changzhou, the enterprise accurately captures the market signals of AIDC industry layout, initiates product adaptation and technological upgrading in the first time, and makes good preparations for technology and production capacity reserves.
As a high-performance computing infrastructure that operates 24 hours a day without interruption, AIDC's high computing power consumption and high safety requirements have put forward four strict standards for supporting transformers: high reliability, high energy efficiency, miniaturization, and intelligence. Wang Junqian frankly stated that "the end of AI is computing power, and the end of computing power is electricity" has become a consensus in the industry, which requires transformers to have zero faults, low losses, and sufficient intelligence. Our dry-type transformers are oil-free, flame-retardant, and explosion-proof, naturally suitable for indoor installation in computer rooms and prioritize safety. This is our core confidence in seizing the market.
Based on the special requirements of AIDC scenarios, enterprises are making efforts in both resource allocation and product development. On the one hand, dedicated production areas are divided, and high-quality supply chains such as high permeability silicon steel sheets and new high-temperature resistant insulation materials are adopted, and a special service team is established to achieve a complete closed-loop process; On the other hand, we will promote energy efficiency upgrades, performance upgrades, and customized upgrades. We need to improve product efficiency to a higher standard, control output voltage deviation within ± 1%, adapt to commonly used AIDC voltage levels such as DC 240V to 800V, and reserve intelligent interfaces. ”Wang Junqian introduced that through a series of technological breakthroughs, the company is fully committed to meeting the differentiated needs of AIDC projects of different scales.
Intelligence and digitization are also key supports for adapting AIDC. Enterprises embed intelligent monitoring modules in AIDC dedicated transformers to real-time collect 12 key parameters such as winding temperature, voltage, current, and partial discharge. The data transmission delay is controlled within 100 milliseconds to achieve real-time perception of equipment status and automatic warning of abnormalities. The remote operation and maintenance cloud platform we have built has increased the fault detection rate to over 95% and shortened the fault handling time by 60%, "said Wang Junjuan. This system highly meets the needs of the AIDC project for" less personnel on duty and efficient operation and maintenance ". At present, the enterprise is promoting the digital upgrade of the workshop, introducing MES manufacturing execution system, realizing data control of more than 100 production nodes, and further consolidating the foundation of intelligence.
The AIDC project has a short construction period and urgent production, which puts strict requirements on the delivery capability and service response speed of suppliers. Our advantage lies in being based in Changzhou and radiating throughout the country, "said Wang Junjuan. The enterprise relies on the superior geographical location and logistics support of Changzhou High tech Zone to build a regional warehousing system, implement the" order priority, special fund production "mechanism, and achieve rapid delivery of conventional specification products within 7 to 15 days. In China, companies have set up service stations in core cities such as Changzhou, Suzhou, Wuhan, and Fuzhou, and opened AIDC project service lines to ensure on-site delivery within 24 hours within the province and 48 hours outside the province, transforming service advantages into competitive advantages.
In 2026, the company will focus on AIDC order delivery and overseas market expansion, striving for a year-on-year sales growth of over 20%. Our original intention is to root ourselves in Changzhou and adhere to craftsmanship. Our mission is to innovate and serve the development of urban industries. In the future, we will continue to deepen our expertise in the field of AIDC dedicated transformers, and contribute the strength of local manufacturing to Changzhou's construction of a high computing power industry in the Yangtze River Delta with smarter, more efficient, and more reliable products. ”Wang Junjuan said.
