Power cable and control cable how to distinguish

Answer:

Power cable, also known as power cable, refers to the transmission of electrical energy cable, the control cable is the transmission of various control signals cable. Power cable transmission continuous current, voltage range of a wide range (from 1KV to 220KV), the current larger (larger conductor), cable core number less, 3 core, 4 core (three-phase four-wire system) 5 core (three-phase five-wire system). Control cable transmission is the signal, the current is relatively small (that is, the conductor cross-section is small), the voltage range is narrow (450/750 ~ 10KV), cable core number is more, from 2 core ~ 61 core, or even more. Control cable also uses a variety of core structure, shielding and other measures to obtain a satisfactory electromagnetic compatibility.

Power (power) cable is used to transmit and distribute power cable, power cable commonly used in urban underground power grid, power station leads lines, industrial and mining enterprises within the power supply and across the river underwater transmission line. In the power lines, the proportion of cable is gradually increasing. The power cable is a cable product used to transmit and distribute high-power power in the main line of the power system, including various voltage classes of 1-500 kV and above, and various insulated power cables. Control cable for industrial and mining enterprises, energy and transportation sector, for the exchange rated voltage 450/750 volts below the control, protection lines and other occasions, the use of PVC insulated, PVC sheathed control cable.

Power cable is a strong power, the control cable is weak
