First, the price of copper wire on the market is relatively cheap. Copper wire is more expensive than aluminum wire, but its performance is better than aluminum wire in all aspects. Because the resistivity of copper wire is very small, it is not easy to heat up during normal use. When in use, heating will affect the power consumption and effect.
Second, the choice of wire The service life of aluminum wire is shorter than that of copper wire, because it is very easy to be oxidized during use, and the resistance of aluminum wire will become larger after oxidation. At this time, it is easy to have safety problems, and the stability of copper wire is better. Moreover, the flexibility of copper wire is better than that of aluminum wire, which is very convenient to bend and has stronger fatigue resistance. In the process of bending, aluminum wire is very easy to break. For household electricity, it is most appropriate to choose safe wires, so we must avoid using aluminum wires to ensure safety.
If there are some problems in the use of wires, it will be more troublesome to maintain them, so don't choose aluminum wires for the sake of cheapness in the process of line selection. Although copper wire is expensive, it also has many advantages. Leakage is a very dangerous thing, so we must pay attention to it.
