2. When the cable tray and process pipeline share the same equipment, the cable tray shall be installed on one side of the pipe rack. When there are flammable gas pipelines, the cable tray shall be set on the power supply side with low risk.

3.當(dāng)規(guī)劃無(wú)規(guī)守時(shí)，電纜橋架層間距離，電纜橋架上層溝頂或樓板及底層溝底或地上距離不宜小于表3的數(shù)值。

3. When planning is irregular and punctual, the distance between layers of cable tray, the distance from the upper layer of cable tray to the trench top or floor and the distance from the bottom layer to the trench bottom or above the ground should not be less than the values in Table 3.

(1)電纜橋架應(yīng)在具有腐蝕性液體管道上方。

(1) The cable tray shall be above the pipe with corrosive liquid.

(2)電纜橋架應(yīng)在熱力管道下方。

(2) The cable tray shall be under the heat pipe.

(3)易燃易爆氣體比空氣重時(shí)，電纜橋架應(yīng)在管道上方。

(3) When flammable and explosive gas is heavier than air, the cable tray shall be above the pipeline.

(4)易燃易爆氣體比空氣輕時(shí)．電纜橋架應(yīng)在管道下方。

(4) When the flammable and explosive gas is lighter than air, the cable tray shall be under the pipe.

4.電纜橋架不宜與下列管道平行敷設(shè)，當(dāng)無(wú)法防止時(shí)，電纜橋架的方位應(yīng)符合下列規(guī)矩。或采用相應(yīng)防護(hù)方法。

4. The cable tray should not be laid in parallel with the following pipes. When it cannot be prevented, the orientation of the cable tray should comply with the following rules. Or adopt corresponding protection methods.

5.電纜橋架與管道之間小距離應(yīng)滿意表4要求。

5. The small distance between cable tray and pipeline shall meet the requirements in Table 4.

6.電纜橋架在下列情況之一者應(yīng)加蓋板或保護(hù)罩。

6. Under any of the following circumstances, the cable tray shall be provided with cover plate or protective cover.

(1)電纜橋架在鐵篦子板或類似帶孔設(shè)備下設(shè)備時(shí)．上層電纜橋架應(yīng)加蓋板或保護(hù)罩．如果在上層電纜橋架寬度小于底層電纜橋架時(shí)．

(1) When the cable tray is under the iron grate plate or similar perforated equipment, the upper cable tray shall be provided with a cover plate or protective cover. If the width of the upper cable tray is less than that of the lower cable tray

(2)電纜橋架設(shè)備在簡(jiǎn)略遭到機(jī)械危害的地方時(shí)應(yīng)加保護(hù)罩。

(2) The cable tray equipment shall be provided with a protective cover when it is slightly damaged by machinery.

7.電纜橋架穿墻設(shè)備時(shí)．應(yīng)根據(jù)環(huán)境條件選用密封設(shè)備。電纜橋架由室內(nèi)穿墻室外時(shí)．在墻的外側(cè)應(yīng)采用防雨方法。

7. When the cable tray passes through the wall, the sealing equipment shall be selected according to the environmental conditions. When the cable tray passes through the wall from indoor to outdoor, the rainproof method shall be adopted on the outside of the wall.

電纜橋架由室外較高處引到室內(nèi)時(shí)．電纜橋架應(yīng)先向下傾斜，然后水平引到室內(nèi)。當(dāng)電纜橋架選用托盤時(shí)，宜在室外水平段改用一段電纜梯架，防止雨水順電纜托盤流入室內(nèi)。

When the cable tray is led indoors from a higher place outdoors, the cable tray shall be inclined downward first, and then led indoors horizontally. When tray is selected for cable tray, a section of cable ladder should be used in outdoor horizontal section to prevent rainwater from flowing into the room along the cable tray.

8.電纜橋架內(nèi)電纜的固定應(yīng)符合相關(guān)標(biāo)準(zhǔn)規(guī)范的規(guī)矩。

8. The fixation of cables in cable tray shall comply with the rules of relevant standards and specifications.
