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.
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.
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.
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 ℃.
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.
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.
