With the development of the Internet, the demand for network lines is also increasing, and the scale of the network is expanding. It needs more high-quality network lines to be laid out. But now there are all kinds of network lines, which one is the most suitable for us, and how should we choose it?
This kind of wire is the best wire, and copper resistance is the second lowest under the same conditions, so it can be used as high quality wire. And suitable for POE power supply, small resistance can avoid the loss of electricity in the transmission process.
2. Aluminum wire
This kind of wire is inferior to copper wire in quality, but it is not a big problem to use it in short distance, so the line of switch, the terminal of household or small office, can choose this kind of wire. Such wires are only suitable for short-distance POE power supply, because the resistance is larger than that of copper wires.
3. Copper clad aluminium wire
This kind of wire is coated with copper outside the aluminium wire. Because of skin effect, the conductivity of the aluminium wire is improved to a certain extent. But this kind of line is also suitable for short-distance POE power supply, also because of the larger resistance.
4. Copper-clad iron wire
This kind of wire is coated with copper outside the wire. Because of skin effect, the conductivity of the wire is improved to a certain extent. But this kind of line is not suitable for POE power supply because of its high resistance.
5. Core wire
This kind of network line has large resistance, which is only suitable for short distance transmission and low network speed requirements. Such lines are not suitable for POE power supply, also because of the high resistance.
6. Mixed Wire
The inner part of this kind of wire is made of copper and aluminum, which is only suitable for short distance use and can be used for POE power supply. But when making crystal head, it must be made in strict accordance with the line sequence. Otherwise, copper wire can not be used for power supply, which will increase resistance and affect the power supply effect.
