The control cable has the characteristics of anti-moisture, anti-corrosion and anti-damage, and can be laid in a tunnel or a cable trench.  Power cables are used in power system trunks to transmit and distribute high-power electrical energy, and control cables transmit electrical energy directly from power distribution points to power connection lines for various electrical equipment. The rated voltage of power cables is generally 0.6 / 1kV and above, and the control cables are mainly 450 / 750V. In the production of power cables and control cables of the same specifications, the insulation and sheath thickness of the power cables is thicker than that of the control cables.
(1) Control cables belong to electrical equipment cables, and power cables are two of the five categories of cables.
(2) The standard for control cables is 9330 and the standard for power cables is GB12706.
(3) The color of the insulated core of the control cable is generally printed in black and white, and the low voltage of the power cable is generally separated.
(4) The cross section of the control cable generally does not exceed 10 square meters. The power cable is mainly used to transmit power, and generally has a large cross section.
