The power cable is used to transmit and distribute large functional power in the main line of the power system, and the control cable directly transfers the electric energy from the power distribution point of the power system to the power connection line of various electrical equipment appliances. The rated voltage of the power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. In the production of power cables and control cables of the same specification, the insulation and sheath thickness of the power cables are thicker than the control cables.
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 separation. The cross section of the control cable generally does not exceed 10 square meters. The power cable is mainly used to transmit power, and is generally large in cross section.
