Control cable This is a polyvinyl chloride-insulated and sheathed control cable, suitable for industrial and mining enterprises, as well as energy and transportation sectors, used in control and protection circuits with AC rated voltages up to 450/750V. The control cable features moisture-proof, corrosion-resistant, and damage-resistant properties, making it ideal for installation in tunnels or cable trenches. Meanwhile, power cables are designed for transmitting and distributing high-power electrical energy along the main lines of power systems, while control cables serve to directly deliver electricity from distribution points within the power system to the power supply connections of various electrical equipment and appliances. Power cables typically have rated voltages of 0.6/1kV and above, whereas control cables primarily operate at 450/750V.
Power cables refer to cables with larger conductor diameters—typically 3- or 4-core—with thicker insulation between phases, designed to transmit electrical energy. They are used for transmitting and distributing high-power electricity in the main lines of power systems. Their rated voltage is generally above 0.6/1 kV, handle large currents, and usually have a smaller number of cable cores.
Control cables are used to transmit control signals, with a rated voltage of 450/750V. They serve as the power connection lines that deliver electrical energy directly from distribution points in the power system to various electrical devices. These cables typically have multiple cores—standardly 61 cores—but can also be custom-made according to specific customer requirements. The key difference between power cables and control cables lies in their functions and applications:
1. Application Field Differences: Power Cables — Cable products used in power systems primarily include overhead bare conductors, busbars (bus ducts), power cables, plastic cables, oil-paper cables (which have largely been replaced by plastic power cables), rubber-sheathed cables, and overhead insulated cables. Additionally, there are branch cables (used as a partial replacement for busbars) as well as electromagnetic wires and electrical equipment wires/cables designed for use in power devices. Control Cables — These are employed in computer systems, information transmission systems, robotic systems, CNC equipment systems, automation systems, traction systems, and more.
2. Core count difference: Power cables—typically have thicker wire diameters and usually come in 3- or 4-core configurations; control cables, on the other hand, often feature a higher core count, with standard options including up to 61 cores.
3. Voltage Difference: Power cables typically have a rated voltage of 0.6/1 kV or higher; control cables have a rated voltage of 450/750 V.
4. Difference in Load Current Flow: Power cables are used in the main lines of power systems to transmit and distribute high-current electrical energy for delivering substantial power, while control cables are designed to carry control signals, directly transporting electrical energy from distribution points in the power system to various end-use devices. The primary distinction between control and power cables lies in the magnitude of current they handle—and consequently, the types of loads they can drive. Additionally, the current-carrying capacity of control and power cables varies significantly depending on the application. Control cables typically feature multiple conductors, whereas power cables usually have three to four cores.
