It needs to have sufficient strength and stability to support the weight and torque of the core or winding mold of the wet transformer during rotation. Its speed range can usually be adjusted according to the winding process requirements, and it has high-precision rotation control to ensure the uniformity of winding.

Similar to other winding machines, it is responsible for arranging the wires neatly on the core or winding mold. Since wet transformers may have special requirements for the insulation and compactness of the coils, the wire arrangement mechanism requires higher precision and can accurately control the wire spacing and wire direction.

To ensure winding quality, this system can ensure that the wire has stable and appropriate tension during the winding process. In wet transformer winding, appropriate tension helps prevent problems caused by loose wires in a humid environment, while avoiding damage to the wire insulation layer due to excessive tension.

The number of turns, winding speed, wiring parameters and tension of the winding can be precisely controlled. Some advanced control systems can also store the winding parameters of various types of wet transformers for easy call and switch.
