電纜橋架在使用過程中會出現脹縮的問題，如果不及時進行處理的話，很有可能就會對電纜橋架產品質量造成一定的影響。那么山東橋架的脹縮問題是什么樣的？

　　Cable tray in the process of use will appear the problem of expansion and contraction, if not dealt with in time, it is likely to have a certain impact on the quality of cable tray products. So what is the problem of expansion and contraction of shandong bridge?

　　由于環境溫度的變化，像是鋼制電纜橋架就會出現熱脹冷縮的現象，室外橋架的作用受溫度影響是比較大的，因此使用中要注意高溫風機溫度的變化才行。室外的山東橋架受溫度影響較大例如情況至高溫度為40℃，至低溫度為-20℃，則電纜橋架的至大縮短量按下式求得：

　　Due to the change of environmental temperature, such as steel cable bridge will appear thermal expansion and cold contraction phenomenon, the role of outdoor bridge is relatively affected by temperature, so pay attention to the change of high temperature fan temperature in use. Outdoor Shandong bridge is greatly affected by temperature. For example, when the maximum temperature is 40℃ and the minimum temperature is -20℃， the maximum shortening of cable bridge can be obtained by following the formula:

　　Δt=11.2×10-6×60deg（度）×1000mm，由此得出結論：溫差為60℃時，Δι=0.672mm/m；溫差為50℃時，Δι=0.560mm/m；溫差為40℃時，Δι=0.448mm/m。

　　δ T =11.2×10-6×60deg （degree） ×1000mm, from which it can be concluded that δ ι=0.672mm/m when the temperature difference is 60℃； When temperature difference is 50℃， δ ι=0.560mm/m; When temperature difference is 40℃， δ ι=0.448mm/m.

　　工程設計中直線段不銹鋼電纜橋架應思索伸縮接頭，伸縮接頭的間距建議按以下取定：當溫差為40℃時為50m；當溫差為50℃時為40m；當溫差為60℃時為40m。

　　In engineering design, the straight line stainless steel cable bridge should consider the expansion joint. The spacing of the expansion joint is recommended as follows: 50m when the temperature difference is 40℃； When the temperature difference is 50℃， 40m; When the temperature difference is 60℃， it is 40m.

　　此外，山東橋架在電纜鋪設中可以說是不可或缺的，它主要用來保護電纜不被損壞，也便于電纜分類鋪設和管理，想要長時間使用電纜橋架需要對其進行保養。如何做好電纜橋架的保養工作呢？

　　In addition, Shandong bridge can be said to be indispensable in cable laying, it is mainly used to protect the cable from being damaged, but also easy to classify the cable laying and management, want to use the cable bridge for a long time need to maintain it. How to do the maintenance of cable bridge?

　　由于電纜橋架的材質原因，使用時間一長，表面可能不如原先鮮亮，這時可以對其進行打蠟處理。可以將表面的灰塵清干凈，然后將光蠟涂抹在橋架表面，等晾干后再擦干。光蠟的使用不僅能使電纜橋架保持鮮亮的光澤，還能增強橋架的抗氧化能力。

　　Due to the material of the cable tray, the surface may not be as bright as before after a long time of use. At this time, it can be waxed. You can clean the dust on the surface, and then smear the light wax on the surface of the bridge, and then dry it after drying. The use of light wax can not only make the cable bridge maintain bright luster, but also enhance the oxidation resistance of the bridge.
