Signal cable is a cable designed to carry current of less than one ampere per conductor, used to transmit information rather than to deliver significant power.
Signal cable is cable designed to carry the small currents associated with transmitting information, generally less than one ampere per conductor. Unlike power cable, which delivers substantial current to operate equipment, signal cable carries the low-current audio, video, data, and control signals that convey information. Its construction is optimized for signal integrity rather than heavy current capacity.
Because signal cable prioritizes preserving the signal, its design emphasizes appropriate conductor size, controlled impedance, low capacitance, and shielding to reject interference. These characteristics keep the information intact as it travels, which is more important than carrying large currents in these applications.
In commercial and industrial systems, signal cable links sources, processors, and displays in audio, video, communication, and control applications. Selecting cable suited to the signals it carries is essential to clean, reliable transmission.
Because signal cable prioritizes preserving the signal, its design emphasizes appropriate conductor size, controlled impedance, low capacitance, and shielding to reject interference, characteristics that keep the information intact rather than focusing on carrying large currents.
Recognizing how signal cable differs from power cable helps illustrate why its design emphasizes conductor size, impedance, low capacitance, and shielding to keep information intact rather than carrying heavy current across commercial and industrial systems.
At Windy City Wire, the focus on quality low-voltage signal cable supports the clean transmission of audio, video, data, and control signals. Supplying cable engineered for signal integrity helps ensure that information reaches its destination accurately across commercial and industrial systems.
