Now in the construction of electric power engineering, cable bridge will be used. This is to protect the quality of the bridge. Therefore, we need to master the correct installation method when we install it. Do you know what the installation method of cable bridge in Shandong Province is? How much do you know about it? Next, let's have a look!

在吊頂內(nèi)設(shè)置時，槽蓋開口面的垂直間隙應保持在80毫米，槽段的利用率不應超過50%。

When it is set in the ceiling, the vertical clearance of the groove cover opening surface should be kept at 80mm, and the utilization rate of the slot section should not exceed 50%.

2.橋架跨越電氣設(shè)備時，橋架與電氣設(shè)備的凈距不得小于0.5毫米，兩組平行鋪設(shè)在同一高度時，凈距不得小于0.6米

2. When the bridge spans the electrical equipment, the clear distance between the bridge and the electrical equipment shall not be less than 0.5mm. When two groups of parallel laying are laid at the same height, the clear distance shall not be less than 0.6m

3.在水平、垂直橋和垂直的山東電纜橋架中敷設(shè)電線時，應捆綁纜線：

3. When laying wires in horizontal, vertical bridges and vertical cable trays in Shandong, the cables shall be bound

根據(jù)纜線的類型、電纜直徑和纜線線芯數(shù)，24對電纜進行捆扎，25對及以上的主干電纜、光纜和其他類型的電纜進行捆扎

According to the type of cable, cable diameter and number of cable cores, 24 pairs of cables are bundled, and 25 pairs of trunk cables, optical cables and other types of cables are bundled

(2)綁扎間距不應大于1.5米，扣間距應均勻，松緊適度。

(2) The binding spacing should not be greater than 1.5m, and the buckle spacing should be uniform and moderately tight.

4.橋架高出地面2.2米以上，橋架頂部頂棚或其他障礙物的距離不應小于0.3米，橋架寬度不應小于0.1米，橋架內(nèi)橫斷面填充率不應超過50%。

4. The bridge should be more than 2.2m above the ground, the distance from the top of the bridge to the ceiling or other obstacles should not be less than 0.3m, the width of the bridge should not be less than 0.1M, and the filling rate of the cross section in the bridge should not exceed 50%.

5.電纜引入點的位置和引入模式。一般來說，大量的電纜可以用垂直彎板和垂直引上引下，少量的電纜可以用導板或引管引下，并可以指示引下方式。

5. Location and mode of cable entry point. Generally speaking, a large number of cables can be led up and down with vertical bending plate and vertical lead, and a small number of cables can be led down with guide plate or lead pipe, and the way of leading down can be indicated.

6.山東電纜橋架上的纜線垂直敷設(shè)時，應每隔1.5米固定在纜線上端橋的支架上，水平敷設(shè)時，應每隔3-5米固定在纜線的頭部、尾部和轉(zhuǎn)彎處。

6. When the cable is laid vertically on the cable tray in Shandong, it should be fixed on the bracket of the end bridge of the cable at an interval of 1.5 meters; when it is horizontally laid, it should be fixed at the head, tail and corner of the cable every 3-5 meters.

7.在平行圖上畫出路線，并注明橋的起點、終點、轉(zhuǎn)折點、分支點和吊點的坐標或定位尺寸和標高。如果能畫出山東槽式橋架鋪設(shè)的軸測圖，材料統(tǒng)計會更準確。

7. Draw the route on the parallel diagram, and indicate the coordinates or positioning dimensions and elevation of the starting point, end point, turning point, branch point and lifting point of the bridge. If the axonometric drawing of Shandong trough type bridge can be drawn, the material statistics will be more accurate.

8.直線段：標明全長、橋?qū)訑?shù)、標高、型號和規(guī)格。轉(zhuǎn)向點和分支點：標明所用轉(zhuǎn)向盤的型號和規(guī)格。吊裝剖面：標明標高變化，可以用局部詳圖或剖面圖表示。

8. Straight line section: indicate the total length, number of bridge floors, elevation, model and specification. Steering point and branch point: indicate the type and specification of the steering wheel used. Hoisting section: Mark elevation change, which can be expressed by local detail drawing or section drawing.

9.橋架支撐點：如立柱、支架或非標支架、框架間距、安裝方式、型號、規(guī)格、標高等，可在平面上列出，也可在不同的斷面、單線圖或詳圖中標注。

9. Bridge support points: such as column, support or non-standard support, frame spacing, installation mode, model, specification and elevation, which can be listed on the plane, or marked in different sections, single line drawings or detailed drawings.

10.鋪設(shè)在線槽上的纜線不得捆綁，線槽內(nèi)的纜線應順直不得盡可能穿越。纜線不應溢出線槽，應綁扎固定在纜線進出線槽的轉(zhuǎn)角處，垂直線槽纜線應每隔1.5米固定在纜線支架上。

10. The cables laid on the trunking shall not be bundled, and the cables in the trunking shall be straight and shall not cross as far as possible. The cables shall not overflow the trunking, and shall be bound and fixed at the corner of the cable going in and out of the trunking. The cables of the vertical trunking shall be fixed on the cable support every 1.5m.

山東電纜橋架是電氣纜線集中管理的主要設(shè)備，除了正確安裝橋架方法外，在出現(xiàn)灰塵或腐蝕性物質(zhì)的地方，應盡量在橋架上加裝蓋板，這樣可以更好地保護電氣纜線。

Shandong cable bridge is the main equipment for centralized management of electrical cables. In addition to the correct installation method of cable tray, cover plate should be installed on the cable tray where dust or corrosive substances appear, so as to better protect the electrical cables.
