Twisted pair is the most common transmission medium in the integrated wiring system. The quality of its quality directly affects the information transmission effect of the wiring system. Therefore, twisted pair occupies an important position in this network project. Let me share with you which material is the best for the network cable.

Pure copper: Copper network cable is the best and best quality network cable, suitable for POE power supply, with small resistance to avoid the loss of electricity during transmission.

Aluminum wire: The quality is inferior to that of copper wire. It is only suitable for short-distance POE power supply. The resistance is larger than that of copper wire.

Copper-clad aluminum wire: This type of wire is electroplated with a layer of copper on the outside of the aluminum wire. Due to the skin effect, the conductivity of the aluminum wire is improved to a certain extent, and the resistance is relatively large. It is only suitable for short-distance POE power supply.

Copper-clad iron wire: This kind of network cable is electroplated with a layer of copper on the outside of the iron wire. Because of the skin effect, the conductivity of the iron wire is improved to a certain extent, and the resistance is large, which is not suitable for POE power supply.
