Explore our premium factory-direct solutions featuring high-performance winding machines, automated core tables, and annealing furnaces.
Evaluating standard requirements, performance demands, and technological paradigms in high-voltage and low-voltage energy grids.
Global power grids are demanding lower losses and higher reliability. Advanced coil manufacturing is at the center of this transformation, optimizing electromagnetic efficiency and reducing thermal losses in dry-type and oil-immersed distribution units.
Transitioning from manual tensioners to precision servo-controlled pay-off stands and foil winding machinery. Dynamic tensioning ensures minimal physical distortion, preserving insulation layers and enhancing the overall lifetime of critical power hardware.
Modern amorphous alloy shearing and CNC cross-cutting lines reduce core magnetostriction and eddy currents. The integration of high-precision turning and assembly tables dramatically lowers assembly times and eliminates manual defects during manufacture.
Deeply Developing the Machinery Industry, Empowering the Future of Energy
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.
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.
After years of development, Shuhong Machinery has a complete R&D-design-production-sales-service industrial chain, with a professional R&D team and modern factories ensuring product quality. Focused on tech innovation, it leads in insulation and temperature control; its products have passed State Grid and international certifications. It has supplied over 2,000 substations, boosting China's power and new energy industries.
1. Shuhong Machinery adheres to the team management philosophy of "People-Oriented, Collaborative Innovation", taking an excellent team as its success foundation.
2. In talent development, it has a comprehensive training system for different positions and encourages employees to join industry technical exchanges.
3. In teamwork, it breaks departmental barriers with cross-departmental collaboration, uses an advanced project management system, and holds regular team-building activities.
4. In incentives, it follows "more work, better performance, better rewards", with a scientific performance appraisal system and benefits like equity incentives, motivating employees' enthusiasm.

Each step in our manufacturing workflow is monitored by micro-sensors and coordinated via central PLC controls. Our vacuum annealing systems eliminate micro-cracks in core materials, ensuring long-term magnetic permeability. Automated tension systems on our foil winders prevent mechanical deformation of copper and aluminum layers, allowing the finished transformer to handle sudden surges without mechanical breakdown or interlayer dielectric failure.
Bridging Chinese engineering capacity with global utility and industrial sector requirements.
Our systems design dry-type transformers and high-voltage coil machinery optimized for wind farms, solar plants, and EV supercharging substations where cyclic load profiles require robust thermal management.
For chemical complexes, metallurgic smelting, and mining sectors. High duty-cycle, harsh-environment transformers produced on our foil winders provide consistent voltage outputs under highly inductive loads.
Global procurement requires certification compliance. All Shuhong machinery outputs conform to IEEE, IEC, GB/T, and CE certifications, streamlining grid integration approvals in North America, the EU, and Southeast Asia.
Staying True to Our Original Aspiration and Striving for Greater Goals
Looking forward, Shuhong Machinery will uphold its business philosophy of "People-oriented, Integrity-driven, Collaborative Innovation, and Quality First." It will deepen focus on electrical and plastics machinery, boost R&D investment to strengthen core technologies, and launch more efficient, energy-saving and intelligent products.
The company will also expand domestic and international markets, cooperate with industry leaders, strive to build an internationally competitive machinery brand, and further contribute to China’s machinery manufacturing and energy sector development.
Premium options for high-power winding arrays, turning assemblies, planar cores, and dry-type transformers.
Expert answers addressing the selection, parameters, and operation of transformer core and coil manufacturing setups.
Foil winding machines utilize wide copper or aluminum sheets instead of round wire. This drastically increases the space factor of the coil, reduces short-circuit mechanical forces, improves heat dissipation, and reduces local eddy-current losses in large-power transformers.
High shear precision prevents structural distortion and burrs at the edges of silicon steel sheets. Burrs cause internal short-circuits between layers, leading to heavy eddy-current losses. Our CNC systems limit burr height to less than 0.02 mm.
Amorphous alloy cores are extremely stress-sensitive. Mechanical stress introduced during cutting and assembly significantly increases core loss. Vacuum annealing under high temperatures relieves these mechanical stresses and aligns magnetic domains, lowering no-load loss.
Our core turning tables are engineered for load capacities of 3 to 10 metric tons. They feature smooth hydraulic actuation, ensuring safe rotation of large transformer cores from a horizontal stacking plane to a vertical assembly plane.
Yes, we supply dual-layer and custom three-layer foil winding machines. These machines are fitted with precise alignment controls and independent tension regulations, allowing simultaneous feeding of multiple foil layers and insulation interlayers.
Our high-voltage wire winders use precise servo-motor wire guides to ensure perfect winding layout without crossover overlap. Constant tension regulation prevents elongation and thinning of the wire insulation layer, maintaining dielectric strength.
Our dry-type designs utilize epoxy resin cast structures under vacuum conditions to eliminate air gaps. This limits partial discharge levels, eliminates oil-leak risk, makes the transformer self-extinguishing, and provides superior resistance to ambient moisture.
We provide full remote telemetry diagnostics, complete installation blueprints, operation manual translations, and dispatch engineer technicians to supervise onsite assembly, commissioning, and staff training for large-scale production setups.
