Advantages
-
🤖
1. Full-Automatic & Labor-Saving Operation
Integrates automatic silicon steel sheet feeding, precise tension control, and real-time winding monitoring. It completely replaces manual winding (which is labor-intensive and error-prone), reducing labor costs by 40%+ and eliminating human-induced defects (e.g., uneven lamination), ensuring consistent quality across batches of R-type planar wound cores.
-
🎯
2. Ultra-High Winding Precision
Achieves ±0.1mm winding accuracy, effectively guaranteeing core concentricity and tight lamination of silicon steel sheets. This avoids air gaps between laminations — a key factor that causes magnetic loss in transformers — directly improving the energy efficiency and stable performance of final R-type core transformers.

🔧
3. Strong Spec Compatibility
Flexibly adapts to R-type planar wound cores of different sizes (e.g., for small distribution transformers or industrial control transformers) and silicon steel types (GO/NGO). No frequent mold replacement or complex parameter debugging is needed, shortening setup time by 50% and enhancing the flexibility of production lines.

4. Efficient & Low-Waste Production
Boasts high-speed winding capabilities (20% faster than semi-automatic equipment) to boost production capacity. The precise tension control prevents silicon steel sheet tearing or deformation during winding, reducing material waste to less than 1%. Its stable mechanical structure also minimizes equipment downtime, ensuring continuous and efficient manufacturing.

Application
🏭
1. Distribution Transformer Manufacturing
It is widely used to wind R-type planar wound cores (made of GO silicon steel sheets) for low-loss distribution transformers (common in power grids and residential/commercial power supply). The machine's ±0.1mm winding precision ensures tight lamination and high concentricity of the core, reducing magnetic loss and no-load noise of the transformer. This helps the final product meet energy-saving standards (e.g., IEC Class 1) and adapt to the demand for efficient power transmission in modern grids.
💡
2. Electronic & Control Transformer Production
For small-sized electronic transformers (used in household appliances like air conditioners, refrigerators) and industrial control transformers (for PLC systems, frequency converters), the machine adapts to miniaturized R-type core specs. It realizes automated winding of thin GO/NGO silicon steel sheets, ensuring the core's compact structure and stable magnetic performance — critical for the miniaturization of electronic devices and the precision of industrial control signals.
🚄
3. Special Transformer Manufacturing (New Energy & Rail Transit)
In the production of photovoltaic inverter transformers and EV charging pile transformers (new energy sector), as well as rail transit auxiliary transformers, the machine provides high-consistency R-type core winding. Its ability to handle diverse silicon steel materials and adjust winding parameters meets the special requirements of these fields — such as resistance to high temperature, low magnetic loss, and long-term stability — laying a foundation for the reliable operation of new energy and rail transit equipment.
