電纜橋架的類型多樣，在我們的生活中也是比較多見的。據(jù)了解，大跨距電纜橋架型式多樣，組裝靈活，適用性強(qiáng)，是大型礦場、橋梁、水電站、隧道等配套橋架的好選擇。下面山東橋架廠家來講講選用大跨距電纜橋架要注意的事情。

There are various types of cable trays, which are also relatively common in our lives. It is understood that large span cable bridges have various types, flexible assembly, and strong applicability, making them a good choice for supporting bridges in large mines, bridges, hydropower stations, and tunnels. Next, Shandong bridge manufacturers will talk about matters needing attention when selecting large span cable bridges.

1、電纜橋架、線槽及其支吊架使用在有腐蝕性環(huán)境中，應(yīng)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(yīng)滿足工程環(huán)境和耐久性的要求。

1. Cable trays, trunking, and their supports and hangers used in corrosive environments 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.

2、電纜橋架在有防火要求的區(qū)段內(nèi)，可在電纜梯架、托盤內(nèi)添加具有耐火或難燃性能的板、網(wǎng)等材料構(gòu)成封閉或半封閉式結(jié)構(gòu)，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(yīng)滿足有關(guān)規(guī)范或標(biāo)準(zhǔn)的要求。

2. In sections with fire protection requirements for cable trays, materials such as plates and nets with fire resistance or flame retardant properties can be added to cable ladders and trays to form a closed or semi closed structure. Measures such as applying fire retardant coatings to the surface of the cable tray and its supports and hangers should be taken, and its overall fire resistance should meet the requirements of relevant national codes or standards.

3、在工程防火要求較高的場所，不宜采用鋁合金電纜橋架。

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

4、電纜梯架、托盤寬度和高度的選擇應(yīng)符合填充率的要求，電纜的梯架和托盤內(nèi)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(yù)留10%～25％工程發(fā)展裕量。

4. The selection of the width and height of the cable ladder and tray should meet the requirements for the filling rate. In general, the filling rate in the ladder and tray of the cable 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.

5、在選擇電纜橋架的荷載等級(jí)時(shí)，電纜橋架的工作均布荷載不應(yīng)大于所選電纜橋架荷載等級(jí)的額定均布荷載，如果電纜橋架的支吊架的實(shí)際跨距不等于2m時(shí)，則工作均布荷載應(yīng)滿足要求。

5. When selecting the load level of the cable tray, the working uniform load of the cable tray should not be greater than the rated uniform load of the selected cable tray load level. If the actual span of the supports and hangers of the cable tray is not equal to 2m, the working uniform load should meet the requirements.

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

6. The specifications and dimensions of various components and supports and hangers should match the straight section and bend through series of trays and ladders under the conditions of meeting corresponding loads.

7、在選擇電纜橋架的彎通或引上、引下裝置時(shí)，不應(yīng)小于電纜橋架內(nèi)電纜小允許彎曲半徑。

7. When selecting the bend through, up lead, and down lead devices for the cable tray, they should not be smaller than the small allowable bending radius of the cable inside the cable tray.

8、對(duì)于跨距大于6m的鋼制電纜橋架和跨距大于2m或承載要求大于荷載等級(jí)D級(jí)的鋁合金電纜橋架，應(yīng)按工程條件進(jìn)行強(qiáng)度、剛度及穩(wěn)定性的計(jì)算或試驗(yàn)驗(yàn)證。

8. For steel cable bridges with span greater than 6m and aluminum alloy cable bridges with span greater than 2m or bearing requirements greater than load level D, strength, stiffness, and stability calculations or test verification shall be conducted according to engineering conditions.

9、幾組電纜橋架在同一高度平行敷設(shè)時(shí)，各相鄰電纜橋架之間應(yīng)考慮維護(hù)、檢修距離。

9. When several groups of cable trays are laid in parallel at the same height, the maintenance and repair distance between adjacent cable trays should be considered.
