1.Power cables are power transmission, while control cables are signal control (one is strong current and the other is weak current)
2.The rated voltage of power cables is generally 0.6/1kV and above, and the control cables are mainly 450/750V.
3.The conductor is thick and the insulation is thick.It's the power line.Signal lines, conductors are generally not large, and most of them are shielded.
