How much do you know about the installation of FRP box ?

1. When the height of the bridge is 50 or 100, there are 6 connecting holes on each end, and when the height is 150 or 200, there are 12 connecting holes on each end.
2. Support distance: The support distance should be less than or equal to the allowable load and support span of the load curve.
3. Bridge Width: When selecting the width of the cable tray, there should be a spare space for adding cables in the future.
4. Separate laying: When there are few power cables and control cables, they can be installed on the same cable tray, but the power cables and control cables must be separated and laid in the middle.
5. Cable fixing: When laying the bridge of the line horizontally, the connection between the bridges should be set at 1/4 of the span as much as possible. Cables running horizontally should be fixed every 2 meters, and cables running vertically should be fixed every 1.5 meters.

FRP box has the characteristics of light weight and high strength, corrosion resistance, aging resistance, flame retardant, insulation, beautiful appearance, convenient construction, no need to paint anti-rust layer, high internal and external surface smoothness, and strong adaptability to the environment. Only the pipe box needs to be bolted to the support frame during work, and the joints and box cover also need to be fastened with bolts, which saves time and effort during installation; due to its good corrosion resistance and other properties, the thermal conductivity of the glass steel pipe box is particularly low Only a few hundredths of metal materials, so the thermal stress generated when working in a large temperature difference environment is much smaller than metal.
