In the wake of the global energy transition, electromagnetic components serve as the critical infrastructure baseline. Advanced coil technology underpins everything from ultra-high voltage (UHV) power transmission grids to high-frequency power electronics deployed in electric vehicle (EV) drivetrains and renewable energy storage systems (BESS).
Traditional magnetic core designs and coil architectures are undergoing massive evolution. The industrial sector is quickly abandoning outdated, loss-heavy stacked laminate layouts in favor of highly optimized configurations, such as 3D triangular wound cores. These modern structures drastically improve electromagnetic flux distribution, minimize eddy currents, and slash structural sound emissions. As global distribution grids face strict mandates to lower thermal dissipation and improve energy efficiency, selecting state-of-the-art coil winders and precision cutting systems has become a baseline operational requirement.
Today's procurement strategies center on obtaining machinery capable of processing high-permeability silicon steel with absolute accuracy. Minimizing localized material stress and keeping tolerances to micro-levels is vital, as even microscopic microstructural variations can scale core loss profiles.

Founded in 2018, Shuhong Machinery has consistently prioritized technological innovation and premium service quality. As a high-tech enterprise, we design and manufacture machinery solutions for the electrical, power system, and plastic processing industries.
The foundation of Shuhong Machinery stems from our founder's technical background. Spending over a decade working on the frontlines of machinery manufacturing—from hands-on technical roles to corporate management—our founder witnessed domestic manufacturing transition from "following" to "running alongside" global peers, predicting the surge in demand for energy-efficient, automated power systems.
During a technical exchange for a State Grid project, the founder identified structural thermal and insulation flaws in traditional stacked core transformer designs. These inefficiencies shortened operational life and compromised grid reliability under high-load cycles. Motivated to address these issues, Shuhong's engineering team worked around the clock to develop a transformer line that reduces temperature rise by 30% and guarantees a 15-year operational lifespan under peak conditions.

3D triangular wound cores feature a continuous, gap-free construction that matches the natural direction of magnetic flux. This design reduces core losses (no-load loss) by up to 25%-30%, minimizes magnetic resistance, and lowers noise levels compared to standard stacked silicon steel laminations.
Our foil winding machines utilize a closed-loop pneumatic/servo tension control system. Precision sensors continuously monitor the tension of the copper or aluminum foil as it unwinds. The PLC controller dynamically adjusts magnetic powder brakes or servo motors, keeping winding tension within a ±1% tolerance band. This precision prevents layer slipping and conductor stretching.
Bending and winding silicon steel strips causes localized mechanical stress, which deforms the metal's crystalline structure and reduces its magnetic permeability. Placing the wound cores in a vacuum annealing furnace at 750°C to 800°C relieves these stresses, restoring optimal magnetic performance and lowering no-load losses.
