Engineered to produce ultra-low no-load loss cores for clean and efficient energy systems.
Transformer no-load losses, commonly termed "core losses" or "iron losses," occur continuously 24/7 as long as the transformer is energized, regardless of the load demand. These losses are primarily composed of hysteresis loss (caused by the cyclic reversal of magnetic domains in the core material) and eddy current loss (induced by magnetic flux variations within the core laminations).
Reducing these permanent losses is a cornerstone of modern power grid optimization. At Wuxi Shuhong Machinery, we develop advanced manufacturing equipment—including 3D wound core curve cutting systems and precision tension-controlled foil winders—specifically engineered to optimize core geometry, improve lamination alignment, and preserve magnetic properties during assembly. This holistic process enables manufacturers to produce high-efficiency, cost-effective transformers that comply with strict international energy targets.

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.
By focusing on core technical upgrades, Shuhong Machinery has pioneered engineering methodologies that limit material stress during core processing. This prevents the deterioration of cold-rolled grain-oriented (CRGO) steel and amorphous alloys, helping partners drastically lower transformer core losses at a competitive price point.

Governments are enforcing strict efficiency minimums like EU Ecodesign Tier 2 and US DOE 2016 standards. Transformer manufacturers must choose between costly raw materials or superior processing machinery to hit target no-load loss parameters without price spikes.
Amorphous alloy cores reduce no-load losses by up to 70% compared to traditional silicon steel. However, they are brittle and highly stress-sensitive. Specialized cutting and processing machines from Shuhong protect these materials from physical stress, preserving their native magnetic performance.
While low-loss transformers carry a higher purchase price, their lifetime energy savings yield high ROI. Buying affordable, high-end production machinery from China allows grid suppliers to produce efficient components at a fraction of Western capital expense.
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.
Our integrated approach controls every phase of core fabrication—from precision geometric cutting to automated multi-tier foil winding. This limits mechanical stress, reduces magnetic core strain, and protects the core's micro-crystalline structures, resulting in reliable, low-loss transformers.
Every step engineered to protect magnetic materials and minimize core losses.
Traditional shearing and manual winding introduce mechanical stresses that deform the grain structure of silicon steel. Under load, these deformed regions create high magnetic resistance and local overheating, inflating no-load losses.
By using CNC cross-cutting lines and 3D curve cutting systems, we maintain minimal shear burrs (under 0.02 mm) and precise stacking angles. This reduces magnetic domain friction and minimizes core loss to maintain peak electrical performance over decades.

Technical answers about optimizing core losses and selecting machinery.
No-load losses (iron/core losses) occur continuously as long as the transformer is connected to the grid, regardless of the consumer load. Load losses (copper losses) vary based on the square of the electrical load current running through the windings.
Our machines feature active tension control and precise wire alignment, preventing core lamination deformation. Reducing physical stress during assembly preserves the core material's low magnetic reluctance and limits hysteresis losses.
3D triangular rolled cores eliminate traditional miter joints, creating a seamless closed-loop magnetic circuit. This minimizes air gaps, matches magnetic flow direction, reduces excitation current, and lowers overall no-load losses.
No. Amorphous alloy ribbons are extremely thin (typically around 25µm) and brittle. Standard silicon steel cutting machines can fracture the material, increasing core losses. Specialized CNC amorphous shearing lines are required to process these cores safely.
