托盤式橋架是由托盤或梯架的直線段、彎通、組件以及托臂（臂式支架）、吊架等構(gòu)成具有密接支承電纜的剛性結(jié)構(gòu)系統(tǒng)之全稱。下面就跟著山東電纜橋架廠家一起來了解下托盤式橋架產(chǎn)品選用要點吧。

Tray type bridge is the full name of the rigid structure system with closely connected supporting cables, which is composed of straight sections, bends, components of trays or ladders, brackets (arm supports), hangers, etc. Let's follow the Shandong cable tray manufacturers to understand the key points of the selection of tray type cable tray products.

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。

Cable trays, trunking and their supports and hangers used in corrosive environment shall be made of corrosion-resistant rigid materials or treated with anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability.

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。

In the section with fire protection requirements, the cable tray can be added with plates, nets and other materials with fire-resistant or flame-retardant properties in the cable ladder and tray to form a closed or semi closed structure, and measures such as painting fire-resistant coating on the surface of the cable tray and its supports and hangers shall be taken. The overall fire resistance performance shall meet the requirements of relevant national codes or standards.

在工程防火要求較高的場所，不宜采用鋁合金電纜橋架。

In places with high fire protection requirements, aluminum alloy cable trays should not be used.

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，控制電纜可取50%～70%，且宜預(yù)留10%～25%工程發(fā)展裕量。

The width and height of cable ladder and tray shall meet the requirements of filling rate. Generally, the filling rate of cable ladder and tray is 50% ~ 70% for power cable and 50% ~ 25% for control cable, and 10% ~ 25% for project development should be reserved.

在選擇電纜橋架的荷載等級時，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的額定均布荷載，如果電纜橋架的支吊架的實際跨距不等于2m時，則工作均布荷載應(yīng)滿足要求。

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

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。

Under the condition that various components and supports and hangers meet the corresponding loads, their specifications and dimensions shall match with the straight section and bend series of trays and ladders.

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

When selecting the bend through or lead-in and lead-down devices of the cable tray, it shall not be less than the small allowable bending radius of the cable in the cable tray.

對于跨距大于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D級的鋁合金電纜橋架，應(yīng)按工程條件進(jìn)行強度、剛度及穩(wěn)定性的計算或試驗驗證。

For steel cable trays with a span of more than 6m and aluminum alloy cable trays with a span of more than 2m or a bearing requirement greater than the load grade D, the strength, rigidity and stability shall be calculated or tested according to the engineering conditions.
