The utility model relates to the technical field of power electron, in particular to equipment special for a transformer. A multilayer foil winding system for an inductance coil of a new energy high-capacity transformer comprises a main control system, a winder in signal connection with the main control system, coil belt unwinding machines for providing a coil belt winding material, a turn-to-turn insulation unwinding machine for providing insulation material and an end insulation unwinding machine, the control system is connected with at least two coil belt unwinding machines which are respectively connected with a material guide device, and the coupled turn-to-turn insulation unwinding machine is respectively arranged above the at least two coil belt unwinding machines. The multilayer foil winding system for the inductance coil of the new energy high-capacity transformer is provided with two coil belt unwinding machines, can simultaneously achieve multilayer foil winding of the inductance coil, and is favorable for improvement of winding production efficiency. Simultaneously the multilayer foil winding can reduce eddy loss in the inductance coil and increase power.
