What is the cable for

What is the cable for

Cable is a kind of electric energy or signal transmission device, usually composed of several wires or groups of wires. Cables are divided into signal cables and power cables. The former is used to transmit signals, such as cable TV cable and telephone cable, while the latter is used to transmit electric energy. The main function of wire and cable is to transmit electric energy, signal and realize electromagnetic conversion. The transmission of electric power is like power cable, overhead line, etc. The transmission of signal is like shaft cable, and the realization of electromagnetic conversion is like enameled wire.

What is the difference between wire and cable

What is the difference between wire and cable

1. The structure is different: the wire is generally composed of several soft wires, and there is a layer of insulating skin outside; The cable is generally composed of one or several insulated wires, and the outside is made of rubber. 2. Different sizes: the wire size is smaller, and the cable size is larger because of its complex structure. 3. The transmission capacity is different: the wire can transmit relatively small power, and the cable has relatively strong bearing capacity. 4. Hardness difference: wire hardness is not as high as cable.

Wire and cable specification

Wire and cable specification

Length: This is one of the commonly used tricks in cutting corners. Some people will say that the number of meters marked on the wire I bought is 100 meters. You should pay attention to it. It has the meter mark, but in the middle part, some unscrupulous businessmen have less than 10 meters. For example, 40 meters will be marked after 30 meters.

Introduction of wires and cables

Introduction of wires and cables

Wires and cables are wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in the broad sense are also referred to as cables, and cables in the narrow sense are insulated cables, which can be defined as: an assembly composed of the following parts; One or more insulated wire cores, and their respective possible cladding, total protective layer and outer protective layer. The cable can also have additional uninsulated conductors. Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion.
