Custom Rectangular Enameled Wire Overview Rectangular copper wire has specific requirements for the R-angle size. It is a special-shaped enamelled wire extended from flat wire, composed of a rectangular conductor (copper, copper alloy, and other materials) and an insulating coat. A bonding coat can also be compounded on the surface of the insulating coat to achieve self-adhesive effect. The R-angle size of flat wires is typically half of the thickness, while rectangular wires

Flat Wire Product Overview Self-bonding enameled copper flat wire adopts Polyamide-Imide insulation with Class 220 thermal grade. It integrates outstanding heat resistance, mechanical toughness and reliable self-bonding property, perfectly matching compact winding designs that demand high slot fill rate and long-term stable operation. The uniform black outer layer brings clear visual distinction, well-suited for high-precision electronic winding scenarios. Technical
