The TONGLI DXJ-2000C Servo CNC Transformer Coil Winding Machine is a large-capacity platform built for factories that must combine heavy coil handling with laboratory-grade winding accuracy. It brings together high-precision constant tension, precise wire layout control, automated insulation, wide wire compatibility, and intelligent recipe storage, letting one operator produce large LV and HV coils of repeatable geometry and electrical performance.
A 3000 mm hardened winding axis and a reinforced bed carry coils up to 4000 kg and support transformer ratings up to 5000 kVA. Dual PLC controllers coordinate the main servo spindle and the traverse carriage, while a load-cell feedback loop continuously adjusts tension so that every turn of copper, aluminium, or foil conductor is wound to the designed force. The automatic insulation head applies inter-layer tape in step with the winding cycle, and the recipe library recalls complete winding programs in seconds.
Key Features- High Precision Constant Tension: Closed-loop load-cell feedback maintains constant wire tension across the entire coil, holding resistance and stray loss to tight tolerances.
- Precise Wire Layout Control: A servo traverse carriage lays each turn at an exact programmable pitch for dense, gap-free layer winding.
- Automated Insulation: An integrated insulation head applies inter-layer and end insulation automatically, raising dielectric reliability and cutting cycle time.
- Wide Wire Compatibility: Processes round, rectangular, and foil conductors from 0.05 mm to 8.0 mm across LV and HV applications.
- Smart Recipe Storage: Stores up to 800 winding programs covering turns, pitch, tension, and insulation, with one-touch recall between coil types.
- Dual Servo Drive: Stepless 0-300 rpm with smooth acceleration and stable braking keeps large, heavy coils fully controlled.

The DXJ-2000C serves transformer plants producing oil-immersed, dry-type, and cast resin transformers up to 5000 kVA, along with heavy reactors and power inductors. It is ideal for mixed, high-volume lines where large coils of differing wire types and winding pitches must be produced with consistent quality, minimal setup time, and low operator dependence.
Packaging & Quality AssuranceEvery machine is assembled, load-tested, and sample-wound at full tension before dispatch, then packed in a seaworthy plywood case with a steel-reinforced base and moisture-proof lining for safe ocean transit. TONGLI provides a one-year warranty, free first commissioning and operator training, and lifetime spare parts support, with remote video commissioning or on-site service available worldwide.
