电缆桥架在使用过程中会出现胀缩的问题，如果不及时进行处理的话，很有可能就会对电缆桥架产品质量造成一定的影响。那么山东桥架的胀缩问题是什么样的？

　　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?

　　由于环境温度的变化，像是钢制电缆桥架就会出现热胀冷缩的现象，室外桥架的作用受温度影响是比较大的，因此使用中要注意高温风机温度的变化才行。室外的山东桥架受温度影响较大例如情况至高温度为40℃，至低温度为-20℃，则电缆桥架的至大缩短量按下式求得：

　　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，由此得出结论：温差为60℃时，Δι=0.672mm/m；温差为50℃时，Δι=0.560mm/m；温差为40℃时，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.

　　工程设计中直线段不锈钢电缆桥架应思索伸缩接头，伸缩接头的间距建议按以下取定：当温差为40℃时为50m；当温差为50℃时为40m；当温差为60℃时为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， 山东桥架在电缆铺设中可以说是不可或缺的，它主要用来保护电缆不被损坏，也便于电缆分类铺设和管理，想要长时间使用电缆桥架需要对其进行保养。如何做好电缆桥架的保养工作呢？

　　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?

　　由于电缆桥架的材质原因，使用时间一长，表面可能不如原先鲜亮，这时可以对其进行打蜡处理。可以将表面的灰尘清干净，然后将光蜡涂抹在桥架表面，等晾干后再擦干。光蜡的使用不仅能使电缆桥架保持鲜亮的光泽，还能增强桥架的抗氧化能力。

　　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.
