The existing enameled wires are all round, which has the disadvantage of low slot full rate after winding. Enameled wire is a main kind of winding wire, which is composed of conductor and insulating layer. The bare wire is annealed and softened, then painted and baked for many times. However, it is not easy to produce products that meet the requirements of both standards and customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various kinds of enameled wires are different, but they all have mechanical properties, chemical properties, electrical properties and thermal properties.



At present, the cross-section shape of enameled wire is round, and its slot full rate is about 78%, which is difficult to meet the requirements of technology development for flattening, lightweight, low power consumption and high performance. Because the current round enameled wire has the disadvantage of low slot full rate after winding, it is urgent to develop a super enamelled aluminum flat wire.
 In order to solve the above technical problems, signi aluminum has developed such a super embedded aluminum flat wire, which includes a flat aluminum wire, an insulating layer and a self-adhesive layer, The thickness of the insulating layer on the left and right sides of the flat aluminum wire section is greater than that on the top and bottom of the flat aluminum wire section, and the thickness of the insulating layer on the top and bottom of the flat aluminum wire section is equal.
Super enamelled aluminum flat wire has a high slot full rate after winding, which can reach about 95%. It has a wide range of uses, and the conductor is thin and uniform in size. The insulation layer can cover the conductor evenly, which can meet the requirements of flattening, lightweight, low power consumption and high performance of key parts.
