梯級式電纜橋架具有重量輕，結構簡單，成本低，強度大，造型別具，安裝方便、散熱、透氣性好等優(yōu)點，使用小量化的連接螺栓，它適用于一般直徑較大電纜的敷設，特別適用于高、低壓動力電纜的敷設。下面濟南橋架廠家來講講選用梯級式電纜橋架應注意的事項：

The stepped cable tray has the advantages of light weight, simple structure, low cost, high strength, unique shape, convenient installation, good heat dissipation and permeability, etc. It uses a small amount of connecting bolts, which is suitable for the laying of cables with large diameters in general, especially for the laying of high and low voltage power cables. The following Jinan cable tray manufacturer will talk about the matters needing attention when selecting the ladder type cable tray:

一、橋架、線槽及其支吊架使用在有腐蝕性環(huán)境中，應采用耐腐蝕的剛性材料制造，或采取防腐蝕處理，防腐蝕處理方式應滿足工程環(huán)境和耐久性的要求。

1、 When using cable trays, trunking, and their supports and hangers in corrosive environments, they should be made of corrosion-resistant rigid materials or undergo anti-corrosion treatment. The anti-corrosion treatment method should meet the requirements of the engineering environment and durability.

二、橋架在有防火要求的區(qū)段內，可在電纜梯架、托盤內添加具有耐火或難燃性能的板、網等材料構成封閉或半封閉式結構，并采取在橋架及其支吊架表面涂刷防火涂層等措施，其整體耐火性能應滿足有關規(guī)范或標準的要求。

2、 In the section with fire protection requirements, the cable tray can be added with fire-resistant or flame-retardant materials such as boards, nets, etc. to form a closed or semi closed structure. Measures such as applying fire-resistant coatings on the surface of the cable tray and its supports and hangers should be taken, and its overall fire resistance performance should meet the requirements of relevant national regulations or standards.

三、在工程防火要求較高的場所，不宜采用鋁合金橋架。

3、 Aluminum alloy cable trays should not be used in places with high fire protection requirements in engineering.

四、電纜梯架寬度和高度的選擇應符合填充率的要求，電纜梯架的填充率在一般情況下，電力電纜可取40%～50%，控制電纜可取50%～70%，且宜預留10%～25%工程發(fā)展裕量。

4、 The selection of cable ladder width and height should meet the requirements of filling rate. In general, the filling rate of cable ladder can be 40% to 50% for power cables, 50% to 70% for control cables, and a 10% to 25% engineering development margin should be reserved.

五、在選擇電纜梯架的荷載等級時，橋架的工作均布荷載不應大于所選橋架荷載等級的額定均布荷載，如果橋架的支吊架的實際跨距不等于2m時，則工作均布荷載應滿足要求。

5、 When selecting the load level of the cable ladder, the working uniform load of the bridge should not exceed the rated uniform load of the selected bridge load level. If the actual span of the support and hanger of the bridge is not equal to 2 meters, the working uniform load should meet the requirements.

六、各種組件及支吊架在滿足相應荷載的條件下，其規(guī)格尺寸應與托盤、梯架的直線段、彎通系列相匹配

6、 Under the conditions of meeting corresponding loads, the specifications and dimensions of various components and supports and hangers should match the straight section and bending series of trays and ladders

七、在選擇橋架的彎通或引上、引下裝置時，不應小于橋架內電纜小允許彎曲半徑。

7、 When selecting the bending or upward or downward devices of the bridge, they should not be less than the small allowable bending radius of the cables inside the bridge.

八、對于跨距大于6m的鋼制橋架和跨距大于2m或承載要求大于荷載等級D級的鋁合金橋架，應按工程條件進行強度、剛度及穩(wěn)定性的計算或試驗驗證。

8、 For steel bridges with a span greater than 6m and aluminum alloy bridges with a span greater than 2m or a load-bearing requirement greater than load level D, strength, stiffness, and stability calculations or experimental verification should be carried out according to engineering conditions.

九、幾組橋架在同一高度平行敷設時，各相鄰電纜橋架之間應考慮維護、檢修距離。

9、 When several groups of cable trays are laid in parallel at the same height, the distance between adjacent cable tray shall be considered for maintenance and overhaul.

在安裝梯式橋架之前，一定要檢查下型號是否正確、產品是否可靠，產品是否有合格證書，正中間曝光和相關鑒定文本文檔。還有橋架表面有沒有缺陷，是否很光滑、很平整、有沒有出現(xiàn)有氣泡、蛻皮和掛灰的現(xiàn)象。更多相關內容就來我們網站http://m.ymmgjx.net進行咨詢吧！

Before installing the ladder type cable tray, it is necessary to check whether the model is correct, whether the product is reliable, whether the product has a certificate of conformity, the middle exposure, and relevant identification text documents. Also, whether there are any defects on the surface of the bridge, whether it is smooth and flat, and whether there are any bubbles, molting, or ash hanging phenomena.
