Flexible flat cable is a kind of flat cable which is made by wrapping multi-strand copper wire stranded conductors with insulating materials and pressing the sheath materials through the production line of high-tech automation equipment. It has the advantages of soft, flexible bending and folding, relatively thin thickness, small size, simple connection, easy disassembly, etc. The number and spacing of wires can be arbitrarily selected to make wiring more convenient, greatly reduce the volume of products, reduce production costs, and improve production efficiency. It is suitable for data transmission cables or power transmission in electrical equipment. Common specifications include 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm and other spacing flexible cable cables.
