In daily life, we need electricity everywhere, whether it is lighting or the use of electrical appliances, we need wires and cables to connect to the power supply. There are many types of wires and cables on the market, there are different types of control cables, power cables and so on, so what is the difference between control cables and power cables? Next, I will briefly introduce it to you.
The difference between power cable and control cable is as follows:
1. The difference in core color: the color of the insulated core of the control cable is generally black printed with white characters, and the low voltage of the power cable is generally color-separated.
2. The difference in the number of cores: the number of cores of power cables is small, there are single cores, two cores, 3 cores, 4 cores (three-phase four-wire system), 5 cores (three-phase five-wire system), according to the requirements of the power grid, the maximum is generally 5 cores. The control cable transmits the control signal, the number of cores is more, from 2 cores ~ 61 cores, or even more. The control cable also adopts various core structure, shielding and other measures to obtain satisfactory electromagnetic compatibility effects.
3. Wire skin difference: power cables require that the wire skin has sufficient compressive strength, tensile strength, temperature resistance and corrosion resistance. The control cable requirements are relatively low.
4. The difference between rated voltage: the rated voltage of power cables is generally 0.6/1kV and above, and the control cable is mainly 450/750V.
Regarding the difference between the control cable and the power cable, the editor will briefly introduce it to you here. I hope that after reading this article, you can understand this. When you buy cables, try to choose brand products with a good reputation.
