昆明鋼制電纜橋架工程

一、昆明電纜橋架工程彎通彎曲半徑一般為70、100、150、200、300、900MM，不建議使用純直角度彎通。
二、有孔電纜橋架，通風面積要少于總面積的百分之四十。
三、電纜橋架支架、吊架和立柱國定托臂的開孔位置或焊接位置，要滿足橋架梯架多層設置時層間中心距為200、250、300、350MM的要求。
四、電纜橋架梯架、拖盤的相對應滿足‘剛度、強度和穩定性的需求。

Kunming steel cable bridge project

I. the bending radius of kunming cable bridge is generally 70, 100, 150, 200, 300 and 900MM, and it is not recommended to use pure straight Angle bending.

2. The ventilation area of the cable bridge with holes shall be less than 40% of the total area.

3. The hole opening position or welding position of cable bridge bracket, suspension frame and pillar state fixed bracket shall meet the requirement that the center distance between layers is 200, 250, 300 and 350MM when the multi-layer of bridge ladder frame is set up.

4. The corresponding structure of the cable bridge ladder frame and towing plate meets the requirements of 'rigidity, strength and stability'.
