Signal wire mainly refers to the line used to transmit sensing information and control information in electrical control circuit. Signal lines are often composed of multiple cables into one or more transmission lines, or printed lines arranged in printed board circuits. With the continuous progress of science and technology and application, signal lines have developed from metal carriers to other carriers, such as optical cables. Signal lines for different purposes often have different industry standards to facilitate standardized production and application.
