Learn about a wide variety of cables
In the eyes of many people, this cable thing is very boring and difficult to understand. Many knowledge about cables is beyond the recognition of ordinary people. To speak up, to thoroughly understand cable knowledge is also a big project. Now Let Xiao Bian take you to know a variety of cables!
Cables for electrical equipment are the most common cables in life. They refer to cables that transmit electrical energy from electrical distribution points to electrical devices, and cables used in electrical installations and signal control devices. The power cable is used to transport and distribute electrical energy. It is often used in power supply applications such as urban underground power grids. Compared to their unique appearance, the "wearing" of bare wires can be described as “simple” because it is a cable with no insulating layer, and it often appears in such occasions as outdoor overhead and connection inside the box. These three types of cables are the most common cables and cables that are most commonly known.
In addition, there are also cables that are not well known to the general public. Winding wire is an insulated wire as a winding or component. In some occasions, it is not difficult to see brown or red, fine wire, enamelled wire. It is a kind of winding wire. They are mainly used in some electromagnetic fields. The communication cable is somewhat "unconventional" because its main function is not to send electric energy but to transmit electric signals. It consists of a plurality of mutually insulated wires forming a cable core and an external sealed communication line. People verbally Often referred to as "data cable" is a typical communication cable.
Different uses mean different designs, and this difference not only fully reflects the material, shape, thickness, and quantity of the online core, the number of layers, materials, and thickness of the insulating layer, and the combination of the core and the insulating layer. . For example, in the vast majority of places with high requirements for electrical conductivity, copper core cable is the best choice.
In addition to the core, insulation, filling structures, and shielding are also important components. The only insulating layer is PVC, PE, XLPE, polypropylene PP, fluorine plastic F, rubber, paper, mica tape and other main components, and the filling structure can also be selected glass fiber filler rope, low-smoke halogen-free flame retardant filler rope, fan-shaped Fill the bar and other materials. See here, do you think that the cable is just "a simple mix of core and insulation material"?
