Although it is impossible to use cables and wires in daily life, how much do you know about the difference between cables and wires, and how much you know about their material structure. Let me share with you all the relevant knowledge. Wire and cable Wire and cable 1. First of all, cables with different materials: usually composed of one or more mutually insulated conductors and an outer insulating layer. Each group of wires is insulated from each other, often twisted around the center, and the outer surface is completely covered by high insulation , has the characteristics of inner power supply and outer insulation of the cable. Wire: usually consists of one or several flexible wires, the exterior is protected by a light and soft sheath, and consists of copper, aluminum flat wires, overhead stranded wires and various types.
It can be seen from the above that the cable conductors are protected by insulation, the exterior is protected by high-density insulation, and the cables are only lightly protected. Each cable is a conductor, and each conductor can be used as a wire. 2. Structural differences Cables and wires have the largest structural difference in size and inside the structure. The cables are complicated and the wires are simple and small. The cable occupies a small space, the insulation distance is small, it is not polluted by the environment, and the interference to the environment is small. 3. Differences in use Bare wires do not have wires without any insulation or protective layer. In addition to transmitting electrical energy and information to the wires, they are also used in manufacturing machines, electrical components and connecting wires, as well as insulated wires with various special requirements. Cables, on the other hand, are protected by an insulating layer and are used to transmit, distribute electrical energy or transmit electrical signals. Fourth, the difference between the physical form of conductors Wires are divided into solid conductors, stranded conductors, braided conductors and other types. According to whether the wire and cable has an insulating layer, it is divided into two types: bare wire and insulated wire. Bare wire refers to a wire without an outer insulation layer or protective sheath outside the wire conductor. The cable is a large wire with a conductor core composed of one or more independent mutually insulated insulated wires and a protective layer.
The number of conductor cores of the wire is small, and the diameter of the conductor of the wire is small, and the structure is relatively simple. The number of conductor cores in the cable is larger, the diameter is larger, and the structure is more complicated. The above is about the difference between cables and wires, do you all understand? After years of production practice in the wire and cable industry, Shanghai Qiyue High Temperature Cable Co., Ltd. has rich experience in cable production and manufacturing technology. It requires more advanced testing methods and technologies, high production efficiency and excellent quality. Welcome to consult.
