Ductility resistance: the aluminum alloy cable tray is 40 lower than the copper cable, which is more conducive to the fastening of the connecting terminal and the fastening of the contact end of the connecting end.

耐蚀性：在空气中电缆桥架的抗腐蚀功能好于铜，铜缆的应用寿按三十年整体规划，电缆桥架的应用寿可以达四十年，这也是以在美国运用的客观事实为根据。

Corrosion resistance: the corrosion resistance of cable tray in the air is better than that of copper. The application life of copper cable is planned as a whole for 30 years, and the application life of cable tray can reach 40 years, which is also based on the objective fact of application in the United States.

坎坷功能：根据GB/T12706中对铜缆设备时坎坷半经的划分，铜缆的坎坷半经是10——20倍线缆直徑，铝合金电缆桥架的坎坷半经不大为7倍线缆直径，应用电缆桥架减少了设备合理布局的室内空间，减少了设备成本，更安装铺设。

Bump function: according to the division of bumpy half diameter of copper cable equipment in GB/T12706, the bumpy half diameter of copper cable is 10-20 times the cable diameter, and the bumpy half diameter of aluminum alloy cable bridge is not more than 7 times the cable diameter. The application of cable bridge reduces the indoor space for reasonable layout of equipment, reduces the equipment cost, and is more installation and laying.

导电率：根据GB/T3956铝合金型材电导体比较于铜电导体加上一个或两种规格型号，抵达同样的电缆载流量，即铝合金型材的横截面加上1.5倍抵达铜同样的导电性。自然横截面增大1.5倍，但通过压紧解决，电导体直径与铜比较只加上1——18mm，加上的非常少。

Conductivity: according to GB/T3956, aluminum alloy profile electrical conductor is compared with copper electrical conductor plus one or two specifications and models to reach the same cable current carrying capacity, that is, the cross section of aluminum alloy profile plus 1.5 times to reach the same conductivity of copper. The natural cross section is increased by 1.5 times, but the diameter of electric conductor is only added by 1-18mm compared with that of copper, which is very small.

可塑性：铝合金电缆桥架由于退火处理后的拉伸强度能到达或超出百分30，高过铜缆的25规范。

Plasticity: the tensile strength of aluminum alloy cable tray after annealing can reach or exceed 30%, which is higher than the 25 specification of copper cable.

份量：同样电缆载流量同样尺寸的铝合金电缆桥架是铜缆的份量的一半，在大跨距设备中优点明显，可以设备成本。

Weight: aluminum alloy cable tray with the same cable carrying capacity and size is half the weight of copper cable. It has obvious advantages in large-span equipment and can reduce equipment cost.
