1, extends the performance of aaac conductor;

 

Elongation is an important indicator of the mechanical properties of the conductor, and the merits of the product, and can withstand an important indicator of the size of the force. But also it is an important indicator of conductor mechanical properties. aaac conductor elongation after annealing treatment can reach 30%, and an elongation of 25% copper, ordinary Pole elongation of 15%, is to replace aaac conductor and copper important indicator.

 

2, flexible performance aaac conductor;

 

Torsion test: the main test of metal wire toughness, toughness better, able to withstand the more the number of twists. An important disadvantage of ordinary aluminum wire is brittle and high, the installation of a certain number of times as long as the twist angle, the conductor will have cracks, splits will heat, and corrosion, which is an important reason for the fire. The use of aaac conductor, due to its good toughness, will not crack, it appears to reduce security risks during installation.

 

3, the bending properties of aaac conductor

 

Bending test: The main test of metal bending performance. Material uneven or brittle materials, bending performance is poor.

 

According to GB / T12706, the provisions of the bending radius copper installed copper cable bend radius is 10-20 times the cable diameter, aluminum cable minimum bend radius of 7 times the cable diameter, the use of an aluminum cable can be reduced layout space, laying easier, reducing installation costs.

 

4, rebound performance aaac conductor;

 

The practice has proved that: at room temperature, the copper and aaac conductor bent 90 degrees, after stress release, aaac conductor bounce angle of 60% copper. Because aluminum cable with no memory, so the stability of the connection rebound better performance than copper cable, terminal connections during the installation process easy fitting pressed to increase its close degree increase.
