Ultrathin 240-level modified polyimide enamel-cover copper flat wire

The utility model provides an ultrathin 240-level modified polyimide enamel-cover copper flat wire, which can overcome the shortcomings of low space utilization factor and small specific surface of an ordinary polyimide enamel-cover copper round wire, and simultaneously effectively solves the problem that the polyimide paint is not suitable for the transportation and storage at normal temperature in production enterprises so as to be suitable for the production of the enamel-cover copper flat wire. The flat wire comprises a copper conductor, wherein the periphery of the copper conductor is coated with a polyimide lacquer layer. The utility model is characterized in that the copper conductor has a rectangular cross section, the size of the wide edge of the cross section of the copper conductor is 1.2mm-14mm, and the size of the narrow edge is 0.2mm-1.00mm.
