2017 cable bridge national standard thickness
cable bridge width u003C100 ~ standard thickness must reach 1mm
100 u003C100 u003C150 ~ standard thickness to reach 1.2mm
150 u003C400 ~ standard u003C400 ~ standard The thickness needs to reach 1.5mm
400 u003C800 ~ standard thickness should reach 2mm
800 u003C1200 ~ standard thickness should reach 2.5mm
The corresponding protection measures, such as: how much the construction environment is anti -corrosion, fire prevention, and rust prevention levels, it is necessary to perform surface treatment of the bridge itself, or select better material manufacturing.
Different cable bridge plates are selected according to different single weights and wire diameters. The thickness of the board is generally not less than 3mm. In addition, it is necessary to perform stress analysis and verification based on the size of the bridge structure. It is necessary to consider the weight of the bridge and the construction load, and other possible loads. The safety factor is not less than 1.5.

The type of cable bridge mainly depends on the composition and use environment of the laying cable. There are some commonly used cable bridge frames on the market for reference:
grocery -type electric answering cable bridge frames: groove cable bridge is a completely sealed cable bridge. Its shape looks like a box. For laying cables.
The ladder cable bridge: The overall is staircase, supported by the center of welding crossbars, light weight, low cost, strong carrying capacity, and good breathability.
The tray -type cable bridge: The tray -type bridge is a semi -sealing bridge, which is very similar to the groove cable bridge. There is a heat dissipation hole at the bottom.
Inmedly based on CECS31: 91, the steel cable bridge engineering design specifications are revised by the China Engineering Construction Standardization Association Electrical Engineering Committee.
