Aluminium alloy cables are made out of high strength
Aluminium-Magnesium-Silicon Alloy. I will tell you some advantages of it as
The alloy material and annealing process of the aluminum alloy conductor reduce the tendency of creep even the conductor under heat and pressure.
Compared with pure aluminum, the creep resistance is improved by 300%, which
avoid the relaxation caused by cold flow or creep.
Tensile strength and elongation
Compared to pure aluminum, due to the addition of special ingredients and the
use of special processing technology, Aluminium alloy conductor greatly improved
the tensile strength, and elongation increased to 30%, higher flexibility
increased to 33% than copper, elastic lower than 40%, the use of more secure and
Thermal expansion coefficient
The coefficient of thermal expansion is used to calculate the dimensional
change of the material as the temperature changes. Aluminum has a thermal
expansion coefficient comparable to that of copper. Aluminum alloy connectors
have been reliably used for copper and aluminum conductors for many years, and
most of the electrical connectors used today are made of aluminum, which is
particularly suitable for aluminum alloys. So the aluminum alloy conductor and
the expansion and contraction of the connector exactly the same.
Electrical connections made with aluminum alloy cables are as safe and stable as
connections made with copper conductors. The composition of the aluminum alloy
greatly improves its connection performance. When the conductor is annealed, the
added iron produces high strength creep resistance, which ensures stable
connection even in the case of long time overload and overheating.
