山東電纜橋架作為保護電纜的產(chǎn)品，一直被應用，它的類型也比較多，有梯式橋架、槽式橋架、有孔托盤式橋架等。橋架既可獨立架設安裝，全部零件均需進行鍍鋅處理，可安裝在建筑物外露天，也可以敷設在建筑物和管廊支架上。
ShandongAs a product for protecting cables, cable trays have been used all the time. There are many types of cable trays, such as ladder trays, trough trays, and perforated tray trays. The bridge can be erected and installed independently, and all parts need to be galvanized. It can be installed in the open air outside the building, or laid on the building and the pipe gallery bracket.
在很多需要保護裸露電線的供電環(huán)境中，如地下停車場、廠房等，都可以看到電纜橋架的應用。
In many power supply environments where exposed wires need to be protected, such as underground parking lots, workshops, etc., the application of cable trays can be seen.
1.腐蝕環(huán)境中使用的電纜橋架、線槽及其支吊架應采用選取耐腐蝕硬質(zhì)材料或經(jīng)過防腐處理，應滿足工程環(huán)境和耐久性的要求。
1. Cable trays, trunkings and their supports and hangers used in corrosive environments should be made of corrosion-resistant hard materials or undergo anti-corrosion treatment, which should meet the requirements of engineering environment and durability.
2.電纜橋架需防火的地段，可在電纜梯架和橋架內(nèi)加入具有耐火或阻燃性能的板、網(wǎng)等材料，形成封閉或半封閉的構架，并采取在橋架及其支吊架表面涂防火涂料等措施，整體耐火性能應符合相關規(guī)范或標準的要求。
2. For areas where the cable tray needs to be fire-resistant, you can add fire-resistant or flame-retardant boards, nets and other materials to the cable ladder and bridge to form a closed or semi-enclosed structure, and apply coating on the surface of the bridge and its supports and hangers. Fire-resistant coatings and other measures, the overall fire resistance performance should meet the requirements of relevant regulations or standards.

3.在防火要求高的地方，選取鋁電纜橋架不適合。
3. In places with high fire protection requirements, it is not suitable to choose aluminum cable trays.
4.電纜梯架和橋架的寬度和高度的選挑應滿足填充率的要求。電纜梯架和橋架填充率在1狀況，以下，電力電纜可選用百分之40百分之50的電纜，控制電纜可選用百分之50百分之70,的電纜，并預留百分之10百分之25項目的開發(fā)余量。
4. The selection of the width and height of the cable ladder and bridge should meet the requirements of the filling rate. If the filling rate of the cable ladder and bridge is below 1, 40-50% of the power cables can be used, and 50% to 70% of the control cables can be used, and 100% are reserved. 10 to 25% of the project's development margin.
5.在選挑，電纜橋架的荷載等級中，電纜橋架的均布荷載不應大于所選電纜橋架荷載等級的額定均布荷載，當假如電纜橋架吊架的實際跨度不等于2m時，電纜橋架的均布荷載應滿足要求。
5. In the selection and selection of the load level of the cable tray, the 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 cable tray hanger is not equal to 2m, the cable tray The uniform load should meet the requirements.
6.在滿足相應荷載的情況下，各種構件、支吊架的規(guī)格和尺寸應與和托盤、梯架直段和彎曲系列相匹配。
6. Under the condition that the corresponding load is met, the specifications and dimensions of various components, supports and hangers should match the straight section and curved series of pallets and ladder frames.
7.當選挑電纜槽彎曲或上下引導設備時，不應小于電纜槽中電纜的較小允許彎曲半徑。
7. When choosing to bend the cable trough or guide the equipment up and down, it should not be smaller than the smaller allowable bending radius of the cable in the cable trough.
8.對于跨度大于6m的鋼索橋和跨度大于2m或承載要求大于荷載等級D的鋁索橋，應根據(jù)工程情況計算或測試實行強度、剛度和穩(wěn)定性。
8. For steel cable bridges with a span greater than 6m and aluminum cable bridges with a span greater than 2m or load requirements greater than load class D, the strength, rigidity and stability shall be calculated or tested according to the engineering conditions.
9.當幾組山東電纜橋架槽與高度平行敷設時，相鄰電纜槽之間的差距應由商酌維護和檢修。
9. When several sets of Shandong cable tray troughs are laid in parallel with the height, the gap between adjacent cable troughs should be maintained and repaired by consultation.
