在很多時(shí)候選擇橋架使用比較多的還是槽式橋架，因此在進(jìn)行選擇的時(shí)候一定要非常的注意，選用要點(diǎn)都有什么呢？下面小編整理了十點(diǎn)要求大家參考一下。

In many cases, the tray used more is the trough tray, so you must pay great attention to the selection. What are the key points of selection? Here are ten points for your reference.

1）槽式電纜橋架及其支吊架在腐蝕環(huán)境中使用，應(yīng)采用耐腐蝕材料或防腐處理。防腐處理方法應(yīng)符合要求。

1) The trough type cable tray and its supports and hangers shall be made of corrosion-resistant materials or treated with corrosion protection when used in corrosive environment. The anti-corrosion treatment method shall meet the environmental protection requirements.

2）在有防火要求的區(qū)段，電纜橋架可在電纜梯和橋架內(nèi)加裝耐火或阻燃板、網(wǎng)等材料，形成封閉或半封閉結(jié)構(gòu)，并采取以下措施：防火層可用于形成封閉或半封閉結(jié)構(gòu)。耐火性應(yīng)符合有關(guān)規(guī)定。

2) In sections with fire protection requirements, fire-resistant or flame-retardant plates, nets and other materials can be added to the cable ladder and cable tray to form a closed or semi closed structure, and the following measures can be taken: the fire-proof layer can be used to form a closed or semi closed structure. Fire resistance shall comply with relevant regulations.

3）在防火要求高的地方，不宜使用藍(lán)薄荷金橋。

3) BLUE MINT golden bridge should not be used in places with high fire prevention requirements.

4）槽式電纜橋架的寬度和高度的選擇應(yīng)滿(mǎn)足填充率要求。一般情況下，電纜梯和橋架中的填充率，電力電纜應(yīng)為40%～50%，控制電纜應(yīng)為50%～70%。，并應(yīng)預(yù)留10%25%的項(xiàng)目開(kāi)發(fā)津貼。

4) The width and height of trough cable tray shall meet the requirements of filling rate. Generally, the filling rate in cable ladder and bridge shall be 40% - 50% for power cable and 50% - 70% for control cable., And 10% to 25% of the project development allowance should be reserved.

5)選擇電纜橋架載荷等級(jí)時(shí)，電纜橋架的工作均布載荷不應(yīng)大于所選電纜橋架載荷等級(jí)的額定均布載荷。如果電纜橋架支吊架的實(shí)際跨度不等于2m，分布荷載應(yīng)符合要求。

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

6）在各種構(gòu)件和支吊架滿(mǎn)足相應(yīng)載荷的情況下，其規(guī)格和尺寸應(yīng)與托盤(pán)和梯架的直段和彎曲系列相匹配。

6) Under the condition that various components and supports and hangers meet the corresponding loads, their specifications and dimensions should match the straight section and bending series of trays and ladders.

7)選擇槽式電纜橋架的直通或引出引下裝置時(shí)，不應(yīng)小于電纜橋架內(nèi)電纜的允許彎曲半徑。

7) When selecting the straight through or leading out and leading down device of the trough cable tray, it should not be less than the allowable bending radius of the cable in the cable tray.

8)跨度大于6m的鋼制電纜橋架和跨度大于2m或承載要求大于D級(jí)的鋁合金電纜橋架，應(yīng)根據(jù)工程條件計(jì)算或驗(yàn)證其強(qiáng)度、剛度和穩(wěn)定性。

8) The strength, stiffness and stability of steel cable trays with a span greater than 6m and aluminum alloy cable trays with a span greater than 2m or a bearing requirement greater than grade D shall be calculated or verified according to the engineering conditions.

9)當(dāng)多組電纜橋架平行敷設(shè)在同一高度時(shí)，應(yīng)考慮相鄰電纜橋架之間的維護(hù)和檢查距離。

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

10)濟(jì)南電纜橋架廠家認(rèn)為槽式電纜橋架直通單件的標(biāo)準(zhǔn)長(zhǎng)度可以是2、3、4、6m。

10) Jinan cable tray manufacturer believes that the standard length of straight through single piece of trough cable tray can be 2, 3, 4, 6m.
