Double Spindle Transformer Coil Winding Machine 800kVA Twin Station High Output

The TONGLI DXJ-2S800 Double Spindle Transformer Coil Winding Machine is a twin-station platform built for workshops that need to increase output without doubling their factory footprint. Instead of winding one coil at a time, the operator loads two coils on two independent spindles and winds them in a shared cycle, effectively doubling throughput on small and medium distribution transformer coils.

Each spindle has its own drive and tailstock, and both are supervised from a single PLC and touchscreen. The operator can run two identical coils in parallel for high-volume batches, or set different parameters per station to wind two variants at once. Automatic wire layout keeps every layer neat and even on both stations, while stored winding recipes let the operator recall complete settings in seconds, so changeovers stay short even on mixed production runs.

• Double Spindle Twin Station: Two independent winding spindles wind two coils per cycle, roughly doubling output on the same machine footprint.
• High Output Winding: Stepless 0-400 rpm on each station with smooth acceleration delivers fast, consistent cycles for volume production.
• Automatic Wire Layout: Motorised traverse carriage lays each turn at a set pitch for uniform, gap-free layers on both coils.
• PLC Recipe Storage: Store up to 200 winding programs and recall them instantly for fast, repeatable changeovers.
• Flexible Batch Modes: Run two identical coils in parallel, or two different variants at once, from a single control panel.
• Compact, Rigid Frame: A single cast bed carries both stations, saving floor space while keeping each spindle stable under load.

The DXJ-2S800 suits small and medium transformer workshops, coil winding job shops, and repair facilities that produce many similar coils every day. It winds the primary and secondary coils of dry-type and oil-immersed distribution transformers up to 800 kVA, as well as reactors, chokes, and small power inductors. Twin-station operation makes it especially productive where throughput matters but floor space is limited.

Each machine is assembled, load-tested, and sample-wound on both stations before dispatch, then packed in a seaworthy plywood case with a steel-reinforced base and moisture-proof lining for safe sea transport. 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.
