Providing cutting-edge industrial transformer winding and cutting equipment configured to meet the grid requirements of Uruguay's distribution network.
Uruguay stands as a global beacon for clean energy, generating over 97% of its electricity from renewable sources, including wind, solar, hydropower, and biomass. Under the leadership of the state utility UTE (Administración Nacional de Usinas y Trasmisiones Eléctricas), the nation is actively expanding grid capacity to accommodate high-fluctuation wind loads from regions like Tacuarembó, Maldonado, and Cerro Largo. Managing this volatile generation requires highly stable distribution transformers capable of minimizing core losses.
Transitioning from traditional flat-stacked planar cores to advanced 3D wound cores and amorphous alloy cores is pivotal for local grid upgrades. With the rural transmission lines across Uruguay spanning vast, low-load densities, the no-load excitation losses of conventional silicon steel transformers become a continuous financial drain. By utilizing Shuhong's advanced core winding machinery, South American manufacturers can assemble low-loss distribution equipment that meets strict local performance baselines, ensuring maximum grid efficiency and system stability.
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 core winding and assembly methodology with 30% lower temperature rise and 15-year lifespan, winning high client recognition.
Specialized industrial equipment designed to eliminate mechanical stress from silicon steel, ensuring optimal magnetic permeability for grid-tie power transformers.
A comprehensive examination of winding geometries, metallurgical stress relief, and cutting tolerances required for modern transformers.
By arranging three core loops into an equilateral triangular pattern, the magnetic path length is balanced across all three phases. This layout eliminates phase imbalances, diminishes harmonic distortion (especially 3rd harmonics), and provides up to a 60% reduction in excitation current compared to planar laminated designs.
Amorphous alloy ribbons are ultra-thin (approx. 25–30 µm) and highly brittle compared to standard silicon steel. Our shearing machinery uses high-rigidity CNC cutters with precision speed control. This preserves the ribbon structure without micro-fracturing, keeping edge-burrs strictly under 0.02 mm.
Mechanical cutting and winding inevitably induce internal stress at the crystalline level of silicon steel, degrading magnetic domain alignment. By heating cores to 800–820°C in an oxygen-free vacuum/inert gas atmosphere and slow cooling, the domain structure is restored, lowering no-load losses by up to 25%.
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.
Ensuring complete structural integrity and optimal operational performance from material sourcing through final performance testing.
Every step of our production pipeline—from raw material longitudinal slitting of CRGO steel coils to final insulation testing and oil injection—is strictly monitored under ISO 9001 protocols. This prevents interlaminar shorts, lowers hot-spot temperatures, and extends the operation of grid assets beyond the standard 15-year baseline.
Furthermore, in order to guarantee maximum alignment in vacuum systems, Wuxi Shuhong employs real-time PLC thermal mapping inside its annealing furnaces. This prevents thermal localized deformation and guarantees high-grade domain recovery across the core structure.
Developing automated, eco-friendly, and high-performance equipment for next-generation grids.
Looking forward, Wuxi Shuhong Machinery will uphold its core business philosophy of "People-oriented, Integrity-driven, Collaborative Innovation, and Quality First." We are steering our research towards deep-level automation, introducing machine-vision-guided cutting blades and real-time tension controllers to eliminate winding defects automatically.

Uruguayan wind-farm grid interfaces face significant variable-load challenges. 3D triangular wound cores feature a balanced three-phase magnetic circuit and jointless metal structures. This decreases no-load losses by up to 60-80% compared to standard planar designs, lowers excitation currents, and provides superior structural strength against harmonic disruptions caused by grid power surges.
Because amorphous ribbons are extremely thin and brittle, typical cutting processes cause domain fragmentation and heavy burrs. Our CNC Shearing equipment is built with high-rigidity structural guides and custom-alloy knives that limit cutting burrs to under 0.02 mm, preventing short circuits within the core layers and maintaining high magnetic permeability.
During the slitting, shearing, and winding steps, silicon steel sheets undergo mechanical stress that distorts their crystalline lattice. Heating the wound cores to around 800-820°C in an oxygen-free vacuum atmosphere restores the crystalline structure and aligns the magnetic domains, significantly lowering the transformer's overall loss-profile.
Yes. Wuxi Shuhong Machinery provides complete international service support. We supply step-by-step remote digital alignment videos and can deploy experienced field-engineers to Montevideo and other South American industrial zones to execute initial machine setup, system calibration, and local personnel training.
By transitioning from conventional manual stack operations to our automatic CNC slitting, tension-regulated winding, and computer-controlled annealing cycles, plant operators typically record a 25% to 35% reduction in overall transformer core losses, which optimizes compliance with green energy grid benchmarks.
