Power cables are used to transmit and distribute large power in the main trunk of the power system. The control cables transmit power directly from the power distribution point of the power system to the power connection lines of various power equipment and appliances. The rated voltage of power cable is generally 0.6/1kv and above, while the control cable is mainly 450/750v. The same specification of power cable and control cable when produced, the insulation and sheath thickness of power cable is thicker than that of control cable.
Control cables belong to the electric equipment cables, and power cables are two of the five categories of cables.
The standard of control cables is 9330, and the standard of power cables is GB12706.
The color of the insulating core of the control cable is usually black printed white, and the low voltage of power cable is usually separated [1].
(iv) the cross section of the control cable is generally no more than 10 square meters. The power cable is mainly used for power transmission, and it is generally a large cross section.
