Professional Cable Tray Manufacturer

The cable tray made of aluminum alloy needs to comply with many standards and specifications, and there are many commonly used specifications, such as 50*50mm, 100*50mm, 100*100mm and so on. The prices of aluminum alloy cable trays with different structures are also different. 
The related contents are as follows: 1. Aluminum alloy bridge trapezoidal aluminum alloy cable tray is a trapezoidal bridge composed of two longitudinal side plates and several horizontal brackets. Trough aluminum alloy cable tray is a trough bridge made of welding bottom plate and side plate or pressed by the whole aluminum alloy plate. 
The force accessories such as connecting pieces and nails of the aluminum alloy cable tray should match the strength of the corresponding bridge tray. The ratio of the maximum deflection to the length of the wall supporting arm of the aluminum alloy cable tray under rated load should not be greater than 1100. 
2. The editor-in-chief of the national standard aluminum alloy cable tray 2000 is the Cable Sub-Committee of the Electrical Engineering Committee of China Engineering Construction Standards Association, and the implementation date is October 1, 2000. the editor-in-chief of the national standard of aluminum alloy cable tray 2019 is the China Electrical Appliance Industry Association, which will be implemented from May 1, 2020. 
The 2000 national standard of aluminum alloy cable tray is suitable for the manufacture, test and inspection of aluminum bridge tray in industrial and civil buildings, as well as engineering design and construction. The aluminum bridge tray selected according to the 2000 national bridge tray standard shall pass the inspection and certification of the national professional quality inspection structure. 
3. Bridge specification when bearing the rated safety load, the relative deflection of aluminum alloy cable tray should not be greater than 1ax 150, and the aluminum alloy cable tray support and hanger should be able to bear the overall weight of the corresponding specifications and layers of the bridge tray within the support span. 
The model content of aluminum alloy cable tray includes component name, structure type, surface protective layer type and specification parameters. When the accessories and supports and hangers of aluminum alloy cable tray meet the safety load, their specifications and dimensions should match the straight-through and bending. 
4. Thickness of bridge tray Aluminum alloy cable tray 2019 National Standard stipulates that when the width of the bridge is greater than 800mm, the thickness of the side plate shall be 3.0mm, and the thickness of the bottom plate, cover plate and connecting plate shall be 1.5mm. 
The thickness size deviation shall comply with the relevant specifications in GB/T 3880.3-2012. 
Aluminum alloy cable tray 2013 industry standard stipulates that when the bridge width is greater than 300mm and less than or equal to 500mm, the thickness of the bridge plate should be 2.0mm, the thickness of the connecting plate of the bridge should be at least 2.0mm, and the minimum thickness of the cover plate of the bridge can be 1.5mm. 
5. The price of cable tray with the same specification and different materials, the price of galvanized cable tray is higher than that of aluminum alloy cable tray, and the price of fiberglass cable tray is cheaper than that of aluminum alloy cable tray. 
For aluminum alloy cable tray of the same material and different structure, the price of slot cable tray is more expensive than that of cascade cable tray, and the price of tray cable tray is more expensive than that of slot cable tray.
