橋架是一個支撐和放電纜的支架。橋架在工程上用的很普遍，只要鋪設電纜就要用橋架。電纜橋架分為槽式電纜橋架、托盤式電纜橋架和梯級式電纜橋架、網格橋架等結構；由支架、托臂和安裝附件等組成。電纜橋架的組成結構應滿足什么要求?山東電纜橋架廠家為您講解：

The bridge is a support for supporting and placing cables. The bridge is widely used in the project. As long as the cable is laid, the bridge must be used. The cable bridge is divided into trough type cable bridge, tray type cable bridge, ladder type cable bridge, grid bridge and other structures; It is composed of bracket, bracket and installation accessories. What requirements should the composition of cable tray meet? Shandong cable bridge manufacturer explains to you:

電纜橋架的組成結構應滿足強度、剛度及穩定性要求，且應符合下列規定：

The composition of cable tray shall meet the requirements of strength, rigidity and stability, and shall meet the following requirements:

①橋架的承載能力不得超過使橋架初產生永久變形時的大荷載除以安全系數為1.5的數值；

① The bearing capacity of the bridge shall not exceed the value of dividing the large load when the bridge initially produces permanent deformation by the safety factor of 1.5;

②梯架、托盤在允許安全工作載荷作用下的相對撓度值，鋼制不宜大于1／200；鋁合金制不宜大于1／300；

② The relative deflection of ladder and tray under the allowable safe working load should not be greater than 1/200 for steel; Aluminum alloy shall not be greater than 1/300;

③鋼制托臂在允許承載下的偏斜與臂長比值不宜大于1／100；

③ The ratio of deflection to arm length of steel joist under allowable load should not be greater than 1/100;

④核電廠安全級電路電纜橋架應滿足抗震Ⅰ類物項設計要求，應同時采用運行安全地震震動和極限安全地震震動進行抗震設計。

④ The cable bridge of the safety-level circuit of the nuclear power plant shall meet the design requirements of seismic Category I items, and the seismic design shall be carried out using both the operational safety seismic vibration and the ultimate safety seismic vibration.
