The wires we see in daily life are used to it, but most of the cables are only in the "heard, never seen" situation. So, what is the difference between wires and cables? Let's tell you some basic common sense of wires and cables.

Wire is a conductor used to transmit electric energy or electrical signal. The cable is usually an inner core composed of two or more wires insulated with each other. The outer part is covered with insulating and reinforcing layer to transmit electric energy or electrical signal. Generally speaking, wires are the general name of wires, most of them are single conductor insulated wires, and their common models are BV, BVR, etc; The cable is relatively large, the conductor is thick, the number of cores, insulation and other characteristics are more than the conductor, and it can be divided into power cable, control cable, computer cable, overhead cable, communication cable, mineral fire-proof cable, etc.

To understand by separation, it can be divided into:

1. The structure of wires and cables is different, and the wires are generally composed of single core or multi strand copper wire conductors, and the conductor is covered with insulating skin; The cable is generally composed of one or several insulated wires, and there will be a sheath on the outer layer of the insulation. According to the different cable types and different uses, the insulation materials and sheath materials used for different specified characteristics are different.
2. The size of the wires and cables is different. Because of the simple structure, the wires are basically small wires (10 mm) below 10 square meters ² For conductor cross-section area), cable is roughly more than 10 square thick conductors due to complex structure and characteristic requirements.
3. The transmission capacity of wires and wires is different. As a small wire with simple structure, the resistance of conductor is limited. If it is a high-power operation, it is necessary to use cable. The conductor of wire basically chooses copper core, and cable can be selected for copper core and aluminum core. When copper core conductor is definitely superior to the transmission capacity of aluminum core conductor.
4. The degree of soft and hard of wires and cables is different. Wires are generally used in household, installation, fire protection and lighting. Single core conductor hard wire or multi strand conductor soft wire is selected according to the use situation; The cable is more hard because of its special structure, which is suitable for engineering laying, hydropower, peripheral power grid, etc.
5. The rated voltage of the wires and cables is different, most of the rated voltage of the wires is 300/500v and 450/750v, while the rated voltage of the cables is 0.6/1kv-26/35kv, which is different from low voltage to high voltage.

In a word, wires and cables are collectively referred to as, which can be generally understood as: the smaller diameter is called "wire", and the larger diameter is called "cable"; The simple structure is called "line", and the complex structure is called "cable". With the rapid development of science and technology, many kinds of "cable in line, cable in cable", we can choose the suitable wire and cable according to their actual situation.
