Can strong and weak electric bridges be merged?

Firstly, cable trays and trunking are different. Due to their almost identical shapes, their performance and functions are greatly different, and the installation price will also be the same. Cable trays will definitely be more expensive.

　　Can strong and weak electric bridges be merged?

Strong current metal cable trays and weak current cable trays cannot be combined and placed in the same tray. A certain parallel distance needs to be maintained between strong and weak current cable trays, and the straight line distance between strong and weak current must be greater than 300MM. This is a standard that weak current must comply with.

But sometimes for the sake of convenience or cost savings, they are often placed together, which seriously violates regulations. The interference generated by strong electricity will directly affect the strength of weak electrical signals.

When installing multiple layers of cable trays, the distance between weak current cables should not be less than 0.2m, the distance between power cables should not be less than 0.3m, and the distance between weak current cables and power cables should not be less than 0.5m. If there is a shielding cover, it can be reduced to 0.3m. The distance between the upper part of the tray and the ceiling or other obstacles should not be less than 0.3m. Cables of different voltages and purposes should not be laid in the same tray.

If it is necessary to lay it in the same layer of bridge due to project constraints, a partition must be added in the middle.

2、 Construction quotation for weak current cable tray

Regarding the installation quotation of the bridge frame, some friends have been asking about it constantly. We have also released it before. This time, we will summarize it for everyone's reference (it is a general quotation, which may fluctuate due to various factors during actual production).

Here, installation prices are provided based on different models.

50-80 (width): 12 yuan per meter (installation height of 4 meters), 18 yuan per meter (installation height of 6 meters).

100-200 (width): 22 yuan per meter (installation height of 4 meters), 25 yuan per meter (installation height of 6 meters).

300 (width): 28 yuan per meter (installation height of 4 meters), 30 yuan per meter (installation height of 6 meters).

400 (width): 32 yuan per meter (installation height of 4 meters), 35 yuan per meter (installation height of 6 meters).

600-800 (width): 35-45 yuan per meter (installation height of 4 meters), 48 yuan per meter (installation height of 6 meters).

900 * 1000 (width): 50 yuan per meter (installation height and width of 4 meters), 55 yuan per meter (installation height of 6 meters).

This data is for reference only, and of course, prices may vary depending on different regions. You can provide a quotation according to your specific situation.

3、 The laying amount of commonly used cable trays

Here are some common utilization rates of commonly used cable trays. Before understanding the utilization rate of cable trays, we can first learn about the core diameters of Category 5e and Category 6 cables.
