Haoshuo's Transformer Winding Machine lineup offers advanced automatic winding machines for power and distribution transformers. As a specialist in transformer manufacturing equipment, Haoshuo provides both high-voltage (HV) and low-voltage (LV) winding solutions. Our coil winding machines handle insulated copper or aluminum wire (flat or round) and are built for dry-type and oil-immersed transformer coils. Our foil winding machines handle copper/aluminum foil strips (with pressure rollers and expanding mandrels) for LV windings and reactor coils. All machines feature CNC/PLC controls, servo drives, automatic tension and wire-guiding. These advanced features ensure high precision, repeatable winding patterns, and efficient production cycles.
Haoshuo winding machines are used throughout the transformer industry – from small distribution transformers to large power units. They support Transformer Coil Winding applications in medium-to-high voltage coils (inductors, reactors, etc.), and Foil Winding Technology for large current LV primaries or reactor windings. Each machine is fully automated: parameters are set via touch-screen interface and winding is executed automatically. Key highlights include photoelectric centering, accurate tension control, programmable layer counts, and optional TIG or cold-press welding of foil ends. Backed by CE certification and rigorous quality control, Haoshuo delivers reliable, high-precision winding solutions tailored for international transformer manufacturers.
Our Product Range
| Feature | Coil Winding Machine | Foil Winding Machine |
| Winding Material | Insulated copper or aluminum wire (round or flat) | Copper or aluminum foil strips |
| Transformer Type | HV/MV/LV transformer coils (dry & oil-immersed; inductors, reactors) | Primarily LV windings or reactor coils for distribution transformers |
| Automation Level | Fully automatic with PLC control, auto wire-arrangement and tensioning | Fully automatic with PLC/servo control, auto foil feeding and splicing |

Why Chose Haoshuo?
Pre-sales Support: Haoshuo engineers provide detailed consultations and custom machine design. We leverage decades of transformer expertise to help customers plan production flows and tailor winding machines to specific requirements.
In-sales Assistance: We coordinate logistics and shipment of equipment worldwide, and offer on-site installation guidance. Our technical team ensures that each winding machine is set up correctly in the customer's factory, minimizing commissioning time.
After-sales Service: A dedicated service team handles installation & commissioning, operator training, and ongoing maintenance. We train customer staff on machine operation and provide timely technical support and spare parts, ensuring long-term reliable operation.
Quality Control: Haoshuo maintains strict production and inspection standards. All winding machines are CE-certified and undergo comprehensive testing (dimensional checks, functional trials, tension accuracy tests, etc.) before delivery. This rigorous QC process guarantees high material utilization and low defect rates.
Product Efficiency: Haoshuo vs. Common Winding Machines
| Performance Metric | Haoshuo Machines | Typical Competitor Machines |
| Winding Speed | Up to 0–200 rpm on HV coils (fast servo-driven). | Slower (~0–150 rpm on similar coils). |
| Setup Time | Quick setup (expandable mandrels, preset programs) – e.g. ~1 hr to switch coils. | Longer manual setup (custom fixtures) – ~2 hr. |
| Maintenance Downtime | Minimal (<5% of runtime); modern design with easy access reduces service time. | Higher (~10% downtime); more routine alignment and maintenance needed. |
| Material Utilization | High (~98% conductor yield); precise cutting and splicing reduce scrap. | Lower (~90% yield); manual splicing can waste extra material. |
| Operators Required | 1 skilled operator (fully automatic PLC control). | 2–3 operators (often semi-auto, requiring manual adjustments). |
