How high-grade manufacturing equipment guarantees electrical safety, minimal thermal dissipation, and long-term operation of step-up systems.
Using automatic tension pay-off systems prevents wire overlap, maintaining consistent electrical resistance and preventing dielectric failure during step-up conversion processes.
Advanced longitudinal CNC slitting of silicon steel minimizes burrs, preserving optimal magnetic permeability and eliminating localized eddy-current heating spots inside transformer cores.
Annealing silicon steel and amorphous metal cores under strict vacuum conditions restores original magnetic properties, mitigating excitation currents and operational noise.
Wuxi serves as a premium center for global power grid components. Direct access to local silicon steel foundries, premium insulation paper mills, and industrial grade toolings significantly minimizes overhead costs. Shuhong passes these structural cost savings directly onto clients, delivering robust step-up transformer equipment without sacrificing electrical safety or components lifespan.
International EPC contractors and grid administrators look for low voltage to high voltage equipment that conforms to IEC, IEEE, and CE standards. Shuhong integrates standardized electronics (SMC pneumatics, PLC control interfaces) into winding machines and custom transformers, facilitating fast system integration, uncomplicated local parts replacement, and global system compliance.
Our technical engineers provide comprehensive documentation including electrical schematics, thermal test reports, and stress-testing certifications. We offer remote installation guidance, localized troubleshooting protocols, and proactive maintenance training, guaranteeing minimum downtime for your sub-transmission systems.
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.
Through our comprehensive production footprint, we combine material slitting, core assembly, and high-frequency winding under one roof. This minimizes external logistics costs and allows us to verify intermediate parameters, resulting in high reliability step-up transformer installations at highly competitive price points.
Shuhong Machinery adheres to the team management philosophy of "People-Oriented, Collaborative Innovation", taking an excellent team as its success foundation.
Since its establishment, Shuhong Machinery has prioritized "meeting customer needs," winning wide acclaim with cutting-edge technology, timely service and full compliance.

From raw silicon steel to precision-tested step-up transformer units, our production steps ensure complete mechanical integrity.
Every step of the production process is carefully regulated by our internal engineers. During the Material Cutting stage, high-speed CNC slitting tools ensure precise margins. In the Winding and Coil Winding stages, automatic tensioners keep tension parameters steady. The Annealing stage uses computerized vacuum furnaces to relieve internal mechanical stress.
Post-assembly processes, including Dry, Oil Injection, and comprehensive electric Testing, ensure that every low-to-high voltage system handles voltage spikes, temperature shifts, and moisture ingress without failure over its designed 15-year operational lifespan.
Where our low voltage to high voltage equipment and transformer components deliver critical electrical performance.
Wind and solar installations generate low-voltage AC/DC power. Highly efficient step-up transformers are essential to convert this low-voltage generation into medium or high voltage for transmission across long distances with minimal power loss.
Heavy machinery like arc furnaces, stamping presses, and automotive assembly lines require high operating voltages. Utilizing local step-up components helps plant managers balance current distribution and prevent voltage dropouts.
In underground mines and civil infrastructure construction, transporting electricity efficiently requires step-up systems. High-quality dry-type and oil-immersed transformers from Shuhong provide safe, reliable operation in harsh environments.
The power engineering sector is transforming. Key shifts in transformer production systems dictate global competitiveness.
Unlike traditional laminated core configurations, 3D wound cores feature continuous, gapless steel structures. This minimizes iron losses and decreases idling currents. In response, manufacturing demands are moving from manual stacking tables to advanced automatic 3D wound core winding machines.
Oil-leak prevention and fire safety are driving sub-transmission designs toward eco-friendly dry-type transformers and synthetic ester-filled systems. This change requires winding equipment that can apply precise tension to modern high-temperature insulation barriers.
Operators now prioritize CNC slitting lines and winding machines with smart diagnostic features. Integrating PLC controls allows systems to monitor wire tension, welding temperatures, and sheet positioning in real-time, helping to prevent production defects before they occur.
Common questions and expert answers regarding low voltage to high voltage manufacturing equipment.
Single-layer winding machines handle one strip of conductive foil (copper or aluminum) and interlaid insulation paper at a time, making them ideal for standard low voltage coils. Three-layer foil winding machines run three distinct layers of conductive foil simultaneously, enabling the construction of high-power coils for large step-up transformers in a single operation, which significantly reduces production times.
If the slitting process leaves uneven edges or micro-burrs, they can bypass the interlaminar insulation coating on the silicon steel sheets, causing internal short circuits and increased eddy currents. This results in high heat dissipation and reduces energy efficiency. Shuhong's CNC slitting equipment maintains tight tolerances to eliminate these issues and minimize core losses.
Mechanical slitting, bending, and winding stress the crystalline structure of silicon steel, which degrades its magnetic performance. Heating the completed cores in a high-vacuum environment relieves these physical stresses and recrystallizes the grain structure, restoring high magnetic permeability and reducing core losses.
Yes. Our winding systems feature adjustable tension and multi-axis configurations, allowing them to wind round, rectangular, planar, and 3D cores using either copper, aluminum, or specialized alloys. This versatility supports the manufacturing of high-efficiency amorphous alloy transformers.
