Multi-conductor magnet wire is manufactured by taking a number of individual winding wires and putting them together in an arrangement specified by the customer, then covering them with a particular insulating material. They are mostly used in the windings of oil-filled power transformers, but also in other electrical equipment.
Categories include paper-insulated, enameled, and bare wire multi-conductor.
