Copper stranded wire is a wire formed by twisting multiple copper wires together at a certain angle. It is made of pure copper or oxygen free copper and has good conductivity and thermal conductivity. Copper stranded wire usually has characteristics such as high flexibility, good strength, corrosion resistance, and wear resistance. Copper stranded wire is suitable for various electrical connections and transmission scenarios, used in fields such as power transmission, communication lines, electrical equipment, and electronic equipment. In power transmission, copper twisted wires are used to carry and transmit current; In the field of communication, copper twisted wire is used as a signal transmission line to transmit audio, video, and data signals. Copper stranded wire is widely used in various industries and fields, and is a common type of wire in electronic accessories.
