Power cables are used in the main lines of power systems to transmit and distribute high-capacity electrical energy, while control cables directly transmit electrical energy from distribution points to the power supply lines of various electrical devices and appliances. The rated voltage of power cables is generally 0.6/1KV and above, while control cables are mainly 450/750V. During production, power cables have thicker insulation and sheaths than control cables of the same specifications.
Control cables belong to electrical equipment cables, and along with power cables, they are two of the five major categories of cables.
The standard for control cables is GB 9330, while the standard for power cables is GB 12706.
The insulation cores of control cables are generally black with white lettering, while low-voltage power cables are usually color-coded.
The cross-sectional area of control cables generally does not exceed 10 square millimeters, while power cables, primarily for transmitting electricity, generally have larger cross-sections.
