The difference between aluminum alloy cable and ordinary cable

Why promote the use of alloy cables?

At the same volume, the actual weight of the aluminum alloy is about one-third that of copper. According to this calculation, the same weight of the aluminum alloy cable is twice as long as the copper cable, while satisfying the same electrical conductivity. Therefore, the weight of the aluminum alloy cable at the same current carrying capacity is about half that of the copper cable. The replacement of copper cables with aluminum alloy cables can reduce cable weight, reduce installation costs, reduce equipment and cable wear, and make installation easier.

Advantages of alloy cables over ordinary cables:

Conductive properties: The conductivity of aluminum alloy is 61.5% of the most commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, which is better than pure aluminum standard.


The aluminum foil, which is generally used as a signal line, is a shielding function for reducing interference of an externally unrelated signal on a transmission signal;


Insulation is done outside for protection or leakage.

The cable foil is an aluminum-plastic composite foil which is formed by applying a film on one or both sides by using the sealing property and shielding property of the aluminum foil, and is used as a shield for the cable. Cable foil requires less oil on the surface, no holes, high mechanical properties, and low overall quality requirements, but the length requirements are extremely strict.
