When it comes to the three terms power cords, wires, and cables, many people don't understand the differences and connections between them, and many people even regard these three as the same product. So let me explain the difference between them below.

　　 In fact, the power cord is the same as the wire, and the power cord is just a more professional term. Then there is the difference between comparison and cable.

　　 Difference 1: Transmission medium

　　 Wire generally conducts electric energy, which is the carrier of electric energy. On the contrary, cables are mainly used to transmit electrical energy, electromagnetic energy, and information, and are wire products that convert these media. It can be seen from the above that the actual transmission medium of cables is far more than that of wires.

　　Difference 2: Material

Generally, wires are composed of one or several relatively soft wires, with a light and soft protective layer on the outermost layer; cables are also composed of one or several insulated wires, but the outer protective layer It is mainly made of metal or rubber. Their structure is the same, but the materials are different.

　　 difference three: appearance

　　The diameter of the general wire is relatively small, and the structure is also very simple. On the contrary, the diameter of the cable is larger than that of the wire, and the structure is relatively more complicated.

　　 Although wires and cables have the above differences, because they were originally used for the transmission of electric energy, they were misled by people as the same product. Although cables can be applied to more industries as their uses evolve, people still habitually mix the two together. Especially in recent years, the existence of wires in cables makes the two more mixed together, there is no big difference.
