Both signal cables and control cables are used in electrical systems, but they are used for different purposes.
Signal cables are used to transmit low voltage and low current electrical signals between devices. They are designed to maintain the integrity of the signal and minimize interference. Signal cables are commonly used in audio and video equipment, computer networks, and instrumentation and control systems.
Control cables, on the other hand, are used to transmit power and control signals between devices, often for industrial applications. They can withstand higher voltages and currents and have additional insulation to protect against mechanical wear and environmental factors. Control cables are commonly used in manufacturing plants, building automation systems and robotics.
To sum up, signal cables transmit low-voltage and low-current electrical signals, while control cables transmit high-voltage and high-current power and control signals.
