大跨距電纜橋架通常是指一米或四米以上，并且橋梁的厚度是根據(jù)標(biāo)準(zhǔn)來(lái)實(shí)現(xiàn)的。由于其屏蔽干擾和控制電纜上的重負(fù)荷而適用于鋪設(shè)計(jì)算機(jī)電纜，通信電纜和其他高靈敏度系統(tǒng)控制電纜等。山東電纜橋架廠家認(rèn)為，選擇大跨距橋架時(shí)應(yīng)注意8個(gè)要素！

Long span cable tray usually refers to one meter or more, and the thickness of the bridge is realized according to the standard. It is suitable for laying computer cables, communication cables and other high sensitivity system control cables due to its shielding interference and heavy load on control cables. Shandong cable tray manufacturer believes that 8 elements should be paid attention to when selecting long-span cable tray!

1）在腐蝕性環(huán)境中使用時(shí)，電纜橋架，線槽及其支撐和吊架應(yīng)使用耐腐蝕的硬質(zhì)材料制成，或者應(yīng)采用防腐蝕處理。防腐處理方法應(yīng)符合工程環(huán)境和耐久性要求。

1) When used in corrosive environment, cable tray, trunking and its supports and hangers shall be made of corrosion-resistant hard materials, or anti-corrosion treatment shall be adopted. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability.

2）對(duì)于具有防火要求的部分的電纜橋架，可以在大跨距電纜橋架中添加耐火或不易燃的板，網(wǎng)和其他材料以形成封閉或半封閉的結(jié)構(gòu)，并用于橋梁和支撐物機(jī)架表面應(yīng)涂防火涂料，其總體耐火性應(yīng)符合相關(guān)法規(guī)或標(biāo)準(zhǔn)的要求。

2) For the cable tray with fire protection requirements, fire-resistant or non flammable plates, nets and other materials can be added to the long-span cable tray to form a closed or semi closed structure, and the surface of the bridge and support frame shall be coated with fire-resistant paint, and its overall fire resistance shall meet the requirements of relevant regulations or standards.

3）鋁電纜橋架不應(yīng)在對(duì)工程防火要求較高的地方使用。

3) Aluminum cable tray shall not be used in places with high fire protection requirements for the project.

4）電纜梯架和橋架的寬度和高度的選擇應(yīng)滿足填充率的要求。通常，電纜梯架和橋架的填充率對(duì)于電力電纜可以為40％-50％，對(duì)于控制電纜可以為50％?70。％，并且應(yīng)保留項(xiàng)目開發(fā)利潤(rùn)的10％-25％。

4) The width and height of cable ladder and tray shall meet the requirements of filling rate. Generally, the filling rate of cable ladders and trays can be 40% - 50% for power cables and 50% for control cables? 70。％， And 10% - 25% of the project development profit shall be retained.

5）選擇電纜橋架的載荷水平時(shí)，電纜橋架的工作均勻載荷不應(yīng)大于所選電纜橋架載荷水平的額定均勻載荷。如果電纜橋架的支架和吊架的實(shí)際跨度不等于2m，則均勻的工作負(fù)荷應(yīng)滿足要求。

5) When selecting the load level 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 level. If the actual span of the support and hanger of the cable tray is not equal to 2m, the uniform working load shall meet the requirements.

6）在各種部件，大跨距電纜橋架滿足相應(yīng)的載荷條件的情況下，其規(guī)格和尺寸應(yīng)與托盤和梯子的直截面和彎頭系列相匹配。

6) When various components and long-span cable bridges meet the corresponding load conditions, their specifications and dimensions shall match the straight section and elbow series of trays and ladders.

7）選擇電纜橋架的彎曲或上下引導(dǎo)裝置時(shí)，其長(zhǎng)度不應(yīng)小于電纜橋架中電纜的允許彎曲半徑。

7) When selecting the bending or upper and lower guiding device of cable tray, its length shall not be less than the allowable bending radius of cables in cable tray.

8）對(duì)于跨度大于6m的鋼制電纜橋架和跨度大于2m的鋁合金電纜橋架或大于D級(jí)載荷的承重要求，應(yīng)根據(jù)工程條件計(jì)算或測(cè)試其強(qiáng)度，剛度和穩(wěn)定性。

8) The strength, stiffness and stability of the steel cable tray with a span of more than 6m and the aluminum alloy cable tray with a span of more than 2m or the load bearing requirements of more than Class D shall be calculated or tested according to the engineering conditions.

9）當(dāng)幾組電纜橋架以相同高度平行放置時(shí)，應(yīng)考慮相鄰電纜橋架之間的維護(hù)和維修距離。

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

此外大跨距橋架在腐蝕性環(huán)境中保護(hù)電纜具有非常好的效果，所以平常使用過(guò)程中要注意對(duì)其的維護(hù)保養(yǎng)，更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://m.ymmgjx.net咨詢了解！

In addition, large-span bridges have a very good effect in protecting cables in corrosive environments, so attention should be paid to their maintenance during normal use. More relevant information can be found on our website http://m.ymmgjx.net Ask about it!
