Power cables are used in the main line of the power system to transmit and distribute large-function electrical energy. The control cables directly transmit electrical energy from the power distribution point of the power system to the power connection lines 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 power cables and control cables of the same specification are produced, the thickness of the insulation and sheath of the power cables is thicker than that of the control cables.
(1) Control cables are cables for electrical equipment, and power cables are two of the five categories of cables.
(2) The standard of control cable is 9330, and the standard of power cable is GB12706.
(3) The color of the insulated core of the control cable is generally black and white, and the low voltage of the power cable is generally color-separated.
(4) The cross-section of control cables generally does not exceed 10 square meters. Power cables are mainly used for power transmission, and generally have large cross-sections.
