有客户跟进这样一个问题，去年冬天她在另一家买了铝合金电缆桥架200米，完工后外型齐整好看，可是近几日高温天气，部分造成翘起现象，变形比较严重，有什么好的解决方案？他非常担忧寒冬后，铝合金电缆桥架再度热缩，小组出线变形、掉下来、乃至破裂等其它比较严重现象。

A customer followed up on such a problem. Last winter, she bought an aluminum alloy cable tray of 200 meters in another company. After completion, the appearance was neat and beautiful. However, in recent days, the high temperature weather has caused some of the phenomenon of warping and serious deformation. What is the good solution? He is very worried that after the cold winter, the aluminum alloy cable bridge will shrink again, and the outgoing line of the group will deform, fall off, and even break.

这里 济南电缆桥架厂家解释一下上述情况是由于工作温度更改,钢制电缆桥架会出现热胀冷缩。

Here, Jinan cable bridge manufacturer explains that the above situation is due to the change of the working temperature, and the steel cable bridge will expand and shrink.

什么叫热胀冷缩呢？热胀冷缩，物理术语，是一个物体一种基本性质，物件在一般状况下，遇热之后澎涨，在受寒状态下会变小。

What is heat expansion and cold contraction? Thermal expansion and contraction, a physical term, is a basic property of an object. Under normal conditions, the object will swell after being heated and become smaller under cold conditions.

桥架归属于金属材料，有热胀冷缩的现象，户外桥架受环境温度影响很大比如自然环境温度为40℃，低温为-20℃。

The cable tray is made of metal materials and has the phenomenon of thermal expansion and cold contraction. The outdoor cable tray is greatly affected by the ambient temperature, for example, the natural ambient temperature is 40 ℃ and the low temperature is - 20 ℃.

若该环境中的温度差非常大，是会有温度差造成桥架变形状况，**在热镀锌电缆桥架的弯管处增加一个伸缩器。有了这个，铝合金电缆桥架也可以安然度过没一个春去秋来。

If the temperature difference in this environment is very large, there will be temperature difference that will cause the bridge deformation. * * Add an expansion joint at the elbow of the hot-dip galvanized cable bridge. With this, the aluminum alloy cable bridge can also spend every spring and autumn in peace.

依据电缆桥架安装标准，直线段钢质电缆架长短超出30m、铝合金或不锈钢制电缆桥架长短超出1.5mm配有伸缩器；电缆桥架超越房屋建筑变形相接处设定补偿装置。您对此有怎样的事项来了解，可以关注我们网站 //www.comprepyme.com咨询！

According to the installation standard of cable tray, the length of steel cable tray in straight section is more than 30m, and the length of aluminum alloy or stainless steel cable tray is more than 1.5mm, equipped with expansion device; The compensation device is set at the junction where the cable bridge exceeds the deformation of the building.
