Constant Tension Transformer Coil Winding Machine Precise Layout 1000kVA Auto Insulation

The TONGLI DXJ-1000H Constant Tension Transformer Coil Winding Machine is a mid-range, high-accuracy platform for workshops that need process control without the footprint of a heavy-duty line. It delivers the same five core strengths as our larger models, namely high precision constant tension, precise wire layout control, automated insulation, wide wire compatibility, and smart recipe storage, in a compact 1500 mm frame that fits easily into a growing production cell.

Even at this size, the DXJ-1000H is a fully digital machine. A load cell closes the tension loop around the wire, a servo traverse carriage lays every turn at an exact pitch, and an automatic insulation head wraps inter-layer tape as the coil builds. Multi-variant producers benefit most: store a winding recipe once, then recall it to reproduce the same coil, wire for wire, day after day, with little dependence on operator skill.

• High Precision Constant Tension: Closed-loop load-cell regulation holds tension constant so every coil achieves a stable, repeatable resistance.
• Precise Wire Layout Control: A servo-driven carriage positions each turn at a programmable pitch for neat, dense layer winding.
• Automated Insulation: An integrated head applies inter-layer insulation automatically, improving dielectric strength and shortening cycle time.
• Wide Wire Compatibility: Winds round, rectangular, and foil conductors from 0.05 mm to 5.0 mm, covering LV and HV small and medium coils.
• Smart Recipe Storage: Saves up to 300 winding programs with turns, pitch, tension, and insulation settings, enabling one-touch changeover.
• Smooth Servo Drive: Stepless 0-360 rpm with gentle acceleration and stable braking for precise, low-noise winding.

The DXJ-1000H is well matched to small and medium transformer workshops, repair facilities, and R&D departments that build dry-type and oil-immersed transformers up to 1000 kVA, along with reactors, ballasts, and small power inductors. Its combination of automatic insulation and smart recipe storage makes it a practical choice for companies that produce many low-volume variants and want consistent quality from a single, space-saving machine.

Each machine is assembled, load-tested, and sample-wound at full tension before shipment, then packed in a seaworthy plywood case with a steel-reinforced base and moisture-proof lining for safe sea transport. TONGLI backs the DXJ-1000H with 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.
