在挑选铝合金桥架时，我们应该对于电缆桥架的性能参数进行分类，这种保障措施非常重要。您知道，铝合金桥架的弯曲性能表现在哪里吗？下面 山东桥架厂家为您讲解。

When selecting the aluminum alloy bridge, we should classify the performance parameters of the cable bridge, which is very important. Do you know what the bending performance of aluminum alloy bridge is? Next, Shandong bridge manufacturer will explain to you.

1、反弹力

1. Rebound force

铝合金桥架的反跳性能比铜缆低40%，更有助于接线端子联接接口处的密切程度上，便于卡紧，提升联接的稳定

The anti-jump performance of the aluminum alloy bridge is 40% lower than that of the copper cable, which is more conducive to the close degree of the connection interface of the terminal, convenient for clamping and improving the stability of the connection

2、导电率

2. Conductivity

依据GB/T3956铝合金型材电导体相较于铜导体增加一个或多个规格型号，做到同样的电缆载流量，即铝合金材料横截面提升1.5倍做到铜相同的导电性实际效果。尽管横截面扩大1.5倍，但是通过紧压解决，电导体直径与铜对比只提升1~18mm，提升的不多。

According to GB/T3956, one or more specifications and models of aluminum alloy profile electrical conductor are added compared with copper conductor to achieve the same cable current carrying capacity, that is, the cross section of aluminum alloy material is increased by 1.5 times to achieve the actual effect of the same conductivity of copper. Although the cross section is expanded by 1.5 times, the diameter of electric conductor is only increased by 1~18mm compared with that of copper through pressing, which is not much.

3、净重

3. Net weight

同样电缆载流量同样的长度铝合金型材电缆是铜缆重量的一半，在大跨度结构安装中优势比较明显，能够降低组装成本费。

The aluminum alloy profile cable with the same cable carrying capacity and the same length is half the weight of copper cable. It has obvious advantages in the installation of large-span structure and can reduce the assembly cost.

4、可塑性

4. Plasticity

铝合金桥架因为退火处理后拉伸强度能抵达甚至超过30%，高过铜缆的25%规范。

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

5、弯曲性能

5. Bending performance

对铜缆安装中弯曲半径的相关规定，铜缆的弯曲半径是10~20倍电缆孔径，铝合金桥架的弯曲半径小编为7倍电缆孔径，应用铝合金型材电缆减少了组装合理布局空间，减少了组装成本费，更加容易铺设。

According to the relevant regulations on the bending radius in the installation of copper cable, the bending radius of copper cable is 10-20 times the cable aperture, and the bending radius of aluminum alloy bridge is smaller than 7 times the cable aperture. The application of aluminum alloy cable reduces the reasonable layout space for assembly, reduces the assembly cost, and makes it easier to lay.

6、耐蚀性

6. Corrosion resistance

空气中铝合金型材电缆的抗腐蚀性能好于铜，铜缆的使用期按三十年设计方案，铝合金型材电缆的使用期能够达四十年。

The corrosion resistance of aluminum alloy profile cable in the air is better than that of copper. The service life of copper cable is designed according to the 30-year plan, and the service life of aluminum alloy profile cable can reach 40 years.

调查电缆桥架的耐蚀性，仅有抗腐蚀，应用的使用寿命才长，才能够很好地维护电缆，环境温度融入覆盖面广，不能因持续高温形变也无法由于超低温而出现开裂。更多相关内容就来我们网站 //www.comprepyme.com咨询吧！

Investigate the corrosion resistance of the cable tray. Only the corrosion resistance and long service life of the application can the cable be well maintained. The ambient temperature can be integrated into the coverage, and it can not be deformed due to continuous high temperature or crack due to ultra-low temperature.
