This equipment is mainly used in all kinds of foil winding in transformer and reactor. Welding method have TIG welding and cold pressure welding .
Features:
1. Adopting motor initiative supplying tension advanced method, stable tension, there is stable tension in foil winding, stopping and foil returning. It can avoid loosen situation when the tension lost in winding
2. Winding speed reducer is turbine shaft reducer, it can keep main shaft auto - locked whenever power on or power off status
3.Correction system using photoelectric analog sensors, it is not meeting with foil edge, both thick and thin foil are accepted .
4. Foil tension, layer insulation tension, coil parameters, winding status and other data, all of them can be set and showed on screen, easy for operating, accurately and intuitively
5.Equipment is controlled by PLC and touch screen, less fault of whole machine, no friction noisy, stable working, high working efficiency.
