電纜橋架的安裝布線可以沿頂板安裝、沿墻水平和垂直安裝、沿豎井安裝，也可以沿地面、電纜溝及管道支架安裝。我們該如何選擇布線方式，金屬線槽布線和電纜橋架布線又有什么不同？下面濟南電纜橋架廠家為您分析：

The cable tray can be installed along the roof, horizontally and vertically along the wall, along the shaft, and along the ground, cable trench and pipe support. How do we choose the wiring method? What is the difference between metal trunking wiring and cable tray wiring? Jinan cable bridge manufacturer will analyze for you:

金屬線槽布線

Metal trunking wiring

（1）金屬線槽布線搬適用于正常環境的室內干燥和不易受機械損傷的場所明敷，但對金屬線槽有嚴重腐蝕的場所不應采用。

(1) The metal trunking wiring is suitable for outdoor laying in dry indoor places and places not vulnerable to mechanical damage in normal environment, but it should not be used in places with serious corrosion to the metal trunking.

（2）同一回路的所有相線和中性線，應敷設在同一金屬線槽內。同一路徑無防干擾要求的線路，可敷設于同一金屬線槽內，線槽內電線或電纜的總截面（包括外護層）不應超過線槽內截面的20％，載流導線不宜超過30根?？刂?、信號或與其相類似的線路，電線或電纜的總截向下應超過線槽內截面的50％，電線或電纜根數下限。

(2) All phase and neutral wires of the same circuit shall be laid in the same metal trunking. Lines with no anti-interference requirements in the same path can be laid in the same metal trunking. The total cross-section of wires or cables in the trunking (including the outer protective layer) should not exceed 20% of the cross-section in the trunking, and the number of current-carrying conductors should not exceed 30. For control, signal or similar lines, the total cross section of wires or cables shall exceed 50% of the cross section in the trunking, and the lower limit of the number of wires or cables.

（3）金屬線槽垂直或傾斜安裝時，應采取措施防止電線或電纜在線槽內移動。

(3) When the metal trunking is installed vertically or obliquely, measures shall be taken to prevent wires or cables from moving in the trunking.

（4）由金屬線槽引出的線路，可采用金屬管，硬質塑料管、半硬塑料管、金屬軟管或電纜等布線方式。電線或電纜在引出部分不得遭受損傷。

(4) The lines led from the metal trunking can be routed by metal pipes, rigid plastic pipes, semi-rigid plastic pipes, metal hoses or cables. The wire or cable shall not be damaged at the outgoing part.

（5）線糟應平整、無扭曲變形，內壁應光滑、無毛刺。

(5) The wiring duct shall be flat without distortion and deformation, and the inner wall shall be smooth without burr.

（6）金屬線槽應可靠接地或接零，但不應作為設備的接地導體。

(6) Metal trunking shall be reliably grounded or connected to neutral, but shall not be used as the grounding conductor of equipment.

電纜橋架布線

Cable tray routing

（1）在室內采用電纜橋架布線時，其電纜不應有黃麻或其他易延燃材料外護層。

(1) When the cable tray is used for indoor wiring, the cable shall not have jute or other combustible materials.

（2）在有腐蝕或特別濕潤的場所采用電纜橋架布線時，應根據腐蝕介質的不同采取相應的防護措施，并宜選用塑料護套電纜。

(2) When cable tray is used for wiring in corrosive or especially wet places, corresponding protective measures shall be taken according to different corrosive media, and plastic sheathed cables shall be selected.

（3）電纜橋架（托盤）水平安裝時的距地高度一般不宜低于2．50m，垂直安裝時距地1．80m以下部分應加金屬蓋板保護，但敷設在電氣專用房間（如配電室，電氣豎井、技術層等）內時除外。

(3) The height of cable tray (tray) from the ground should not be less than 2.50m when installed horizontally, and the part below 1.80m from the ground should be protected by metal cover plate when installed vertically, except when it is laid in special electrical rooms (such as distribution room, electrical shaft, technical floor, etc.).

（4）電纜橋架水平安裝時，宜按荷載曲線選取佳跨距進行支撐，跨距一般為1．5～3m。垂直敷設時，其固定點間距不宜大于2m。

(4) When the cable tray is installed horizontally, the best span should be selected according to the load curve for support, and the span is generally 1.5~3m. When laying vertically, the spacing between fixed points should not be greater than 2m.

（5）幾組電纜橋架在同一高度平行安裝時，各相鄰電纜橋架間應考慮維護、檢驗間隔。

(5) When several groups of cable trays are installed in parallel at the same height, the maintenance and inspection interval between adjacent cable trays shall be considered.

（6）在電纜橋架上可以無間距敷設電纜，電纜在橋架內橫斷面的填充率：電力電纜不應大于40％；控制電纜不應大于50％。

(6) The cable can be laid on the cable tray without spacing, and the filling rate of the cross section of the cable in the tray: the power cable should not be greater than 40%; The control cable shall not be more than 50%.

（7）下列不同電壓，不同用途的電纜，不宜敷設在同一層橋架上：

(7) The following cables with different voltages and different purposes should not be laid on the same bridge:

lkV以上和1kV以下的電纜。

Cables above 1kV and below 1kV.

同一路徑向一級負荷供電的雙路電源電纜。

Two-way power cable supplying power to primary load in the same path.

應急照明和其他照明的電纜。

Cables for emergency lighting and other lighting.

強電和弱電電纜。

Strong and weak current cables.
