Optimized systems designed for high-efficiency winding and cutting to meet rigorous local environmental standards.
Berlin and the wider Brandenburg region are witnessing a massive industrial transition driven by Germany's ambitious Energiewende (Energy Transition). The expansion of municipal grids, the integration of utility-scale renewable energy farms, and the rapid deployment of electric vehicle charging infrastructure require a new generation of power distribution systems. Transformers are the backbone of this transition, and traditional stacked cores no longer satisfy the strict efficiency requirements of modern grids.
The European Union's Ecodesign Directive Tier 2 requirements mandate a significant reduction in no-load losses for distribution transformers. This regulation has accelerated demand for 3D wound cores and amorphous alloy cores within the Berlin industrial cluster. Factories in Berlin-Spandau, CleanTech Park Marzahn, and adjacent Brandenburg hubs require specialized machinery capable of processing high-permeability grain-oriented silicon steel (CRGO) and brittle amorphous ribbons with minimal mechanical stress, ensuring optimal electromagnetic performance.

Analyzing the shift from traditional stacked structures to advanced wound core layouts across international markets.
European and global regulations are driving no-load loss limits down. Wound cores offer continuous magnetic paths, eliminating the air gaps typical of mitred joints, thereby cutting losses by up to 30% compared to traditional configurations.
Amorphous metal ribbon displays up to 75% lower core losses than standard CRGO silicon steel. Processing this material requires specialized CNC shearing lines that protect the ribbon's structural integrity, prevent micro-cracks, and maintain magnetic properties.
Transitioning from manual or semi-automated operations to high-speed CNC winding systems ensures precise layer control, optimal space factor, and consistent mechanical tensioning across production runs.
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.
Under the leadership of our founder, who brings over a decade of hands-on machinery manufacturing experience, Shuhong Machinery has expanded its technical footprint to design high-efficiency, energy-saving transformer production lines. Driven by insights gained from critical state-level energy infrastructure projects, we have successfully developed core processing solutions that reduce transformer temperature rises by 30% and extend overall operational lifespans up to 15 years.
The Founder's Passion for Machinery and Entrepreneurial Journey
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.

Technical clarifications on core winding machinery operations and specifications.
3D wound cores feature a continuous steel strip design that matches the direction of magnetic flux. This eliminates standard 90-degree corner joints, reducing no-load losses by roughly 30% and significantly lowering structural vibration and sound emissions.
Cutting, slitting, and winding apply stress to the grain-oriented silicon steel or amorphous ribbon, which degrades magnetic domain alignment. Heating the core to approximately 800°C (depending on material specs) in a vacuum annealing furnace relieves these mechanical strains, restoring optimal permeability and low loss characteristics.
Silicon steel and amorphous alloys have different material characteristics, such as thickness and hardness. Amorphous ribbon is thin and brittle, requiring high-precision shearing blades and tension controls to avoid micro-fractures, whereas silicon steel demands heavy-duty slitting and shear tools. We build dedicated machines optimized for each specific material class.
Our machines are configured to match major international standards. We supply units with compliant safety enclosures, emergency shut-offs, high-grade electrical components, and programmable logic controller interfaces that adapt to European factory standards.
