Mechanical properties of aluminum alloy cable

 Mechanical properties of aluminum alloy cable

 First、The extensibility of aluminum alloy cable

Elongation is an important indicator of mechanical properties of conductors, and is an important symbol of the quality of products and the ability to withstand external forces. It is also an important index for testing the mechanical properties of cable conductors. The elongation of aluminum alloy cable after annealing treatment can reach 30%, while the elongation of copper cable is 25% and the elongation of ordinary aluminum rod is 15%. It is an important index to replace the cable and copper cable of aluminum core.

Second、Flexibility properties of aluminum alloy cables

Torsion test: the toughness and toughness of metal wire are mainly tested, and the more twists can be borne. An important disadvantage of common aluminum wire is the high brittleness. In the installation of a certain angle of torsion, the conductor will produce cracks, the crack will heat and corrosion, which is an important cause of the fire. Using aluminum alloy cable, because of its good toughness, it will not produce cracks, and there will be fewer safety hazards in installation.

Third、Bending properties of aluminum alloy cables

Bending test: mainly tests the bending resistance of metals. Material with uneven material or brittle material has poor bending resistance.

According to the stipulate of the bending radius of the copper cable installed in GB/T12706, the bending radius of the copper cable is 10-20 times the diameter of the cable, the bending radius of the aluminum alloy cable is 7 times the diameter of the cable. The layout space can be reduced by the aluminum alloy cable, and it is easier to lay the cable and reduce the installation cost.

Forth、Bounce performance of aluminum alloy cable

Practice has proved that the rebound angle of aluminum alloy cable is 60% of that of copper cable after bending the copper cable and aluminum alloy cable 90 degrees at room temperature and releasing the stress. Because the aluminum alloy cable has no memory, so the performance of the rebound is better than the copper core cable. In the process of installation, the terminal connection joint is easy to press tight, increase its tightness, and improve the stability of the connection.
