Claims8
A system for producing helix windings used for a transformer, comprising:
- a power supply;
- a container holding an electrolyte solution;
- an anode connected to a positive terminal of the power supply, disposed in the container, and surrounded by the electrolyte solution;
- and
- an electrically conductive mandrel comprising:
- an elongated body;
- a head comprising an eyelet detail connected to a negative terminal of the power supply;
- and
- a winding structure disposed along the elongated body,
- wherein the elongated body, the head, and a portion of the winding structure that is not to be electroplated are covered in an insulating material, and
- wherein the eyelet detail is not covered in the insulating material.
