Why use Aluminium Wire instead of Copper?
For the wires used in the home, copper core wires are basically used at this stage.
The earliest Aluminium wires have been basically replaced and rarely appear in home decorations.
But you will find that some overhead wires outside are basically made of Aluminium cores.
So why not use copper wire for outdoor wires?
This post will answer specific questions about the selection of outdoor wire materials.
Why not use copper wire for outdoor wires? Copper wire conducts electricity better, so why use Aluminium wire?
Why aren’t the outside cables indicated here made of copper wires, but of Aluminium wires?
Yet, the conductivity of copper wire is significantly superior to that of Aluminium wire.
What causes this to occur?
That is, you are still unfamiliar with the installation conditions of outside wire circuits.
5 reasons for this situation will be told so that everyone can understand.
The characteristics of overhead lines determine the use of Aluminium wires.
For overhead lines, you will know that the wires are hung in the air by means of poles or towers. There are specifications for the weight of the wires since overhead circuit cables are hanging in the air.
Aluminium actually has the second-highest conductivity, behind copper.
Aluminium’s conductivity is roughly two-thirds that of copper, while its density is only one-third that of copper.
As a result, in the overhead state, Aluminium wire is preferable.
Outdoor wires are also affected by their own gravity and environmental influences.
The simplest point, for example, will be impacted by changes in air and temperature, which is our ordinary thermal expansion and contraction.
The ability of the Aluminium wire to withstand thermal expansion and contraction is better than that of copper wire, so it is more suitable to use Aluminium wire for overhead wires.
