The Difference Between Power Cord And Control Cord

Power cables are used on the mains of power systems to transmit and distribute large amounts of electrical energy. Control cables transmit electrical energy directly from the distribution points of the power system to the power connections of various electrical equipment and appliances. The rated voltage of the power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. When the power cable and control cable of the same specification are produced, the insulation and sheath thickness of the power cable is thicker than that of the control cable.

Control cables are cables used in electrical equipment, and power cables are two of the five main types of cables. The color of the insulating core of the control cable is generally black and white, and the low voltage of the power cable is generally color-separated.

The cross-section of the control cable is usually no more than 10 square meters, and the power cable is mainly used for power transmission and usually has a larger cross-section.

Due to the above reasons, the size of the power cord can usually be larger, up to 400 square meters, and there are relatively few manufacturers that can make the larger cross-section, while the cross-section of the control cable is generally small, generally no more than 10 square meters.

In terms of the number of cable cores, according to the requirements of the power grid, the power cable is generally 5 cores, while the control cable is used to transmit control signals, and the number of cores is more.
