Compact 300mm wide Foil winding machine series for LV transformers

Heavy duty coil winding machine series This all-new design, together with our latest high-tech control system, improves quality of winding and reduces machine maintenance to a minimum. Heavy duty coil winding machine series
The foil and insulation de-reelers are provided with an automatically controlled brake system, which applies a constant tension to the materials during the winding process.
The winding unit is equipped with a pressure roller system and the machine is supplied with two expanding mandrels for the copper foil and two for the paper insulation.
The "state of the art" CNC with colour touch screen, precision servo motor drives, and bespoke software provide continuous control and monitoring of all of the process parameters, together with the capacity to store thousands of programs.
There are various configurations possible, up to 500mm width. Compact machine foot print and easy access for the operator help in easy winding of primaries reducing production cycle times.
A typical machine includes:
