Difference between control cable and power cable

June 29, 2023

The power cable is used to transmit and distribute the large-functional power in the main line of the power system, and the control cable transfers the power directly from the power distribution point of the power system to the power connection lines of various appliances 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 power cables and control cables of the same specifications are manufactured, the insulation and sheath thickness of power cables is thicker than that of control cables.

(a) The control cables belong to the cables for electrical equipment, and the power cables are two of the five categories of cables.

(b) The standard for control cables is 9330 and the standard for power cables is GB12706

(3) The color of the insulated wire core of the control cable is generally black and white, and the low voltage of the power cable is generally a color separation.

(4) The cross-section of the control cable will generally not exceed 10 square meters. The power cable is mainly used for power transmission and generally has a large section.

Due to the reasons mentioned above, the specifications of power cables can generally be larger, up to 500 square meters (range that conventional manufacturers can produce), and there are relatively few manufacturers that can do large cross-sections, and the cross-section of control cables is generally small. Smaller, the maximum is generally not more than 10 square.

From the perspective of the number of cable cores, the power cable is generally up to 5 cores according to the grid requirements, while the control cable transmits control signals with a higher number of cores. According to the standard, there are more than 61 cores, but it can also be produced according to user requirements. .
