What is aluminum alloy cable

Aluminum alloy cable is a new type of material power cable using advanced technology such as special compaction process and annealing treatment. Aluminum alloy cable makes up for the shortcomings of the previous pure aluminum cable, improves the electrical conductivity, bending performance, creep resistance and corrosion resistance of the cable, and can ensure that the cable maintains continuous performance and stability when overloaded and overheated for a long time.

Performance of aluminum alloy cable

1. Creep resistance

The special alloy formula and heat treatment process of aluminum alloy conductors greatly reduce the "creep" tendency of the metal under heat and pressure, which is basically consistent with the creep performance of copper conductors and is as stable as the connection made of copper conductors.

2. Corrosion resistance

Compared with copper core cables, aluminum alloy power cables have higher corrosion resistance and can withstand various forms of corrosion; It has better oxidation resistance, and the oxidation corrosion resistance is 10 to 100 times that of copper cable. In sulfur-containing environments, such as railway tunnels and other similar places, the corrosion resistance of aluminum alloy power cables is much better than that of copper core cables.

3. Mechanical performance

First, the bending property. According to the provisions of the bending radius of copper cable installation in GB/T12706, the bending radius of copper cable is 10-20 times the cable diameter, and the bending radius of aluminum alloy power cable is at least 7 times the cable diameter. The use of aluminum alloy power cable reduces the space of installation layout, reduces the installation cost, and is easier to lay.

Second, flexibility. Aluminum alloy power cables have stronger flexibility than copper core cables, and even if they are repeatedly stressed, they will not crack. This reduces security risks during installation.

Third, tensile strength and elongation. The tensile strength of aluminum alloy power cable is 1.3 times that of copper core cable, and the elongation can reach or exceed 30%, which enhances the reliability and beauty of long span installation.
