What Are Control Cables and How Do They Differ from Power Cables?
Power and control cables serve distinctly different purposes in industrial applications. Power cables are designed to carry high-voltage electricity to operate machinery, while control cables transmit low-voltage signals for equipment control, monitoring, and automation systems.
'Understanding the various types of control cables is crucial for proper system design,' explains Dr. Sarah Mitchell, electrical engineering professor at Industrial Technology Institute. 'Each type serves specific applications, and selecting the wrong cable type can compromise entire control systems.'
