Before understanding the utilization rate of the bridge, we can first understand the core diameter of the lower super category 5 wire and category 6 wire.
900 * 1000 (width): 50 yuan per meter (installation height and width is 4m), 55 yuan per meter (installation height is 6m).
Class VI wire core diameter: 0.574; Section: 30.1754; Super class V / class V core diameter: 0.511; Section: 19.625; Take the utilization rate of bridge as an example.

2、 The setting out quantity of common bridges and the utilization rate of common bridges are listed here.
You can quote according to the specific situation.
This data is for reference.
600-800 (width): 38-45 yuan per meter (installation height of 4m), 48 yuan per meter (installation height of 6m).
100-200 (width): 25 yuan per meter (installation height of 4m), 27 yuan per meter (installation height of 6m).
Here is the installation price according to different models.
Of course, it will vary from place to place, so the price will vary.
We’d better not exceed 40% in actual use.
So how to calculate the bridge? For example, it is known that the cross-sectional area of category 6 network cables is 30.1754mm2580.
1、 Construction quotation of weak current bridge installation quotation has been asked by friends for your reference (it is a general quotation, which may fluctuate due to the influence of many factors).
50-80 (width): 18 yuan per meter (installation height of 4m), 22 yuan per meter (installation height of 6m).
400 (width): 34 yuan per meter (installation height: 4m), 37 yuan per meter (installation height: 6m).
What type of bridge is more suitable for Category 6 cables? First, we calculate the cross-sectional area of 580 class 6 lines? 30.1754mm2*580=17501.73mm2; Since the utilization rate cannot exceed 40%; 17501.73mm2/40%=43754.3mm2; Therefore, the total cross-sectional area of the bridge shall be greater than 43264.1mm2; Therefore, the closest bridge models are 150 * 300, 200 * 300, 100 * 600, etc..
300 (width): 30 yuan per meter (installation height: 4m), 32 yuan per meter (installation height: 6m).
