Direct from Wuxi Shuhong Machinery. Explore our high-efficiency systems optimized for standard power grids, dry-type transformers, and high-precision core winding.
On the shores of the picturesque Taihu Lake lies Wuxi, known as the "Land of Fish and Rice." This beautiful land has nurtured countless enterprising enterprises, with Wuxi Shuhong Machinery Technology Co., Ltd. standing out among them. Since its establishment in 2018, Shuhong Machinery has consistently prioritized technological innovation and quality service, steadily advancing in the fields of electrical and plastic machinery, becoming a high-tech enterprise with both strength and reputation.
We design and manufacture high-efficiency machinery systems and processing lines. Our engineering ethos bridges the gap between state-of-the-art transformer efficiency requirements and robust machinery processing standards.
Uncovering the shift toward high-performance materials, multi-layered dielectric integrity, and smart automation in the power sector.
Global distribution networks are shifting towards dry-type transformers due to environmental and fire safety regulations. These installations demand advanced winding insulation structures that handle higher dielectric stress without liquid coolant mediums.
The evolution of 3D triangular rolled cores and planar wound cores requires precise, tension-controlled foil winding equipment to reduce core loss. Automated high-speed manufacturing is now critical for processing complex core geometries.
Even minor tension variations during the winding process can cause microscopic layer cracks. Advanced closed-loop servo controls and multi-axis tension control systems protect insulation materials from micro-tears during winding.
How front-line field experience transformed into a drive for energy-efficient, robust mechanical upgrades.
Shuhong Machinery originated from its founder’s insight into machinery manufacturing. With over a decade in the industry (from front-line technical roles to management), the founder witnessed domestic machinery shift from "following" to "running alongside" global peers, and sensed the need for energy-efficient, intelligent upgrades.
During a State Grid project exchange, the founder found traditional transformers flawed in temperature control and service life (harming power stability, raising costs) and noted new energy’s higher equipment demands—thus focusing on R&D and manufacturing of high-efficiency, energy-saving transformers.
Overcoming funding and technical hurdles, the team worked day and night in labs/workshops on demos and optimizations, finally developing a transformer with 30% lower temperature rise and 15-year lifespan, winning high client recognition.
Wuxi Shuhong Machinery leverages its local supply chain integration in Jiangsu province. By combining raw material processing, high-precision thermal slitting, and computerized tension-controlled coil winding, we ensure predictable production cycles even during periods of high global market demand.
We implement automated manufacturing systems that integrate raw material inspection, mechanical tension feedback loops, and automated thermal performance testing. This unified supply chain approach helps global buyers control costs, reduce production errors, and achieve long-term insulation reliability.
Every winding machine, transformer, and insulation system follows a standardized quality control process. We manage physical stress, thermal behavior, and dielectric properties at each stage of production.
CNC slitting systems prepare the silicon steel coils and copper/aluminum foils without edge burrs.
Foil winding and vacuum annealing furnaces relieve internal mechanical stress and optimize core grain structure.
Precision assembly of the coil winding configurations is followed by thermal drying to remove residual moisture.
For liquid systems, oil injection occurs under vacuum, followed by load losses, partial discharge, and temperature rise testing.
Material Cutting → Winding → Annealing → Coil Winding → Assemble → Dry → Oil Injection → Testing
