LOW VOLTAGE
Foil Winding Machines
The FWM series foil winding machines are designed for production LV coils of distribution, power and cast resin transformers with one or two copper or aluminum foils.
The main control panel with 15” color touch screen allows easy creating winding program. All programmed steps for cooling channel or lead out operations will be automatically stopped at all necessary positions and advises the operator about the next step. Our winding control system allows for easy changes of the software according to the Purchaser’s needs and language.
The machine can be equipped with one or two foil decoilers. Each decoiler is equipped with drive, hydraulic expandable mandrel, swiveling tailstock, pressing rolls and brake. Its own regulated brake system allows to wind coils under constant foil tension regardless of foil’s different thickness or coil’s size.
Edge alignment ensures precise conductor positioning on the coil during winding process.
The standard design of machine is equipped with two insulation decoilers and three end-fill strips on each side.
Each insulation decoiler can be pulled out of the machine to easy load supply coil. The mandrels are pneumatically expandable to allow quick and easy loading.
Paper alignment ensures manual paper positioning on the insulation decoiler after loading supply coil.
Three end-fill strips ensure to get required thickness on both sides of coil.
Winder is equipped with main drive, faceplate, counter bending roller.
