Automatic HV Coil Winding Machine ( with Graded Layer Insula) Features
- Automatic winding of distribution transformer HV coils with inter layer Insulation.
- Winding of conductors along with feeding of inter layer insulation & edge strips without any manual intervention.
- Insulation layer built in a graded profile with thickness varying in proportion to the voltage differential.
- Pneumatically operated collapsible mandrel & retractable tail-stock for easy component handling.
- High precision closed-loop servo tension controller for conductor and insulation strips.
- User-friendly programming and touch-screen based operations.
- Regenerative type drive system with common DC rail for winder & un-winder for lower power consumption.
Benefits.
- Reduces winding cycle time, manual intervention & operator skill, improves consistency & quality.
- Reduces insulation material significantly, since only minimum necessary thickness is provided at every position for each layer.
- Reduces overall material consumption by 5 to 7% due to coil dimensions.
- Reduces stock materials by allowing fewer standard strip dimensions even for different coil widths.
