Power cables are used to transmit and distribute high-power electrical energy within the main lines of power systems. Control cables transmit electrical energy directly from the power distribution points of the power system to the power connections of various electrical equipment. The rated voltage of power cables is generally 0.6/1kV and above, while that of control cables is primarily 450/750V. When manufacturing power cables and control cables of the same specifications, the insulation and sheath thickness of power cables are thicker than those of control cables.
Firstly, control cables are cables for electrical equipment and, along with power cables, are two of the five major cable categories.
The standard for control cables is 9330, while the standard for power cables is GB12706.
The insulation core of control cables is generally black with white lettering, while low-voltage power cables are generally color-coded.
The cross-section of control cables generally does not exceed 10 square meters. Power cables, primarily used for power transmission, generally have larger cross-sections.
