有客戶跟進這樣一個問題，去年冬天她在另一家買了鋁合金電纜橋架200米，完工后外型齊整好看，可是近幾日高溫天氣，部分造成翹起現象，變形比較嚴重，有什么好的解決方案？他非常擔憂寒冬后，鋁合金電纜橋架再度熱縮，小組出線變形、掉下來、乃至破裂等其它比較嚴重現象。

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.

這里濟南電纜橋架廠家解釋一下上述情況是由于工作溫度更改,鋼制電纜橋架會出現熱脹冷縮。

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.

什么叫熱脹冷縮呢？熱脹冷縮，物理專業術語，是一個物體一種基本性質，物件在一般狀況下，遇熱之后澎漲，在受寒狀態下會變小。

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.

橋架歸屬于金屬材料，有熱脹冷縮的現象，戶外橋架受環境溫度影響很大比如自然環境溫度為40℃，低溫為-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 ℃.

若該環境中的溫度差非常大，是會有溫度差造成橋架變形狀況，**在熱鍍鋅電纜橋架的彎管處增加一個伸縮器。有了這個，鋁合金電纜橋架也可以安然度過沒一個春去秋來。

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.

依據電纜橋架安裝標準，直線段鋼質電纜架長短超出30m、鋁合金或不銹鋼制電纜橋架長短超出1.5mm配有伸縮器；電纜橋架超越房屋建筑變形相接處設定補償裝置。您對此有怎樣的事項來了解，可以關注我們網站http://www.pembertonchristian.com咨詢！

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.
