Features

01

Good creep resistance

The alloy material and annealing process of aluminum alloy conductors reduce the "creep" tendency of conductors under heat and pressure. Compared with pure aluminum, the creep resistance is improved by 300%, avoiding the relaxation problem caused by cold flow or creep.

02

Higher tensile strength and elongation

Compared with pure aluminum conductors, the tensile strength of aluminum alloy conductors is greatly improved, and the elongation is increased to 30%, which is safer and more reliable to use.

03

Excellent connection performance

The composition of aluminum alloy improves its connection performance. When the conductor is annealed, the added iron will produce high-strength creep resistance, which can ensure the stability of the connection even if the joint is overloaded and overheated for a long time.

04

Strong self-weight bearing capacity

Aluminum alloy improves the tensile strength of pure aluminum. Aluminum alloy cables can withstand 4,000 meters of self-weight, while copper cables can only support 2,750 meters.

05

Good corrosion resistance

When the aluminum surface comes into contact with air, a thin and strong oxide layer will form, which has a certain corrosion resistance. Adding rare earth elements to the alloy can further improve the corrosion resistance of aluminum alloy, especially electrochemical corrosion.

06

Good flexibility

Aluminum alloy has good bending performance, its flexibility is 30% higher than copper, and its rebound rate is 40% lower than copper. The bending radius of general copper cables is 10-20 times the outer diameter, while the bending radius of aluminum alloy cables is only 7 times the outer diameter, which is convenient for connection.

07

Good compatibility with connectors

The thermal expansion coefficient of aluminum alloy is equivalent to that of copper, so the expansion and contraction of aluminum alloy conductors and connectors are exactly the same.
