（1）金屬線槽布線搬適用于正常環(huán)境的室內(nèi)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 exposed laying in dry indoor places and places not prone to mechanical damage in normal environment, but shall 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(nèi)。同一路徑無防干擾要求的線路，可敷設于同一金屬線槽內(nèi)，線槽內(nèi)電線或電纜的總截面（包括外護層）不應超過線槽內(nèi)截面的20％，載流導線不宜超過30根。控制、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(nèi)截面的50％，電線或電纜根數(shù)下限。

(2) All phase wires and neutral wires of the same circuit shall be laid in the same metal trunking. Lines without anti-interference requirements in the same path can be laid in the same metal trunking. The total cross-section (including outer sheath) of wires or cables in the trunking shall not exceed 20% of the cross-section in the trunking, and the number of current carrying conductors shall not exceed 30. For control, signal or similar lines, the total section of wires or cables shall exceed 50% of the section in the trunking, and the lower limit of the number of wires or cables.

（3）電纜橋架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(nèi)移動。

(3) When the metal trunking of cable tray is installed vertically or obliquely, measures shall be taken to prevent the 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 out from the metal trunking can be wired by metal pipe, hard plastic pipe, semi-hard plastic pipe, metal hose or cable. Wires or cables shall not be damaged at the outgoing part.

（5）線糟應平整、無扭曲變形，內(nèi)壁應光滑、無毛刺。

(5) The wire slot shall be flat without distortion and deformation, and the inner wall shall be smooth without burrs.

（6）電纜橋架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) The metal trunking of cable tray shall be reliably grounded or connected to neutral, but shall not be used as the grounding conductor of equipment.

本施工方案使用的是外殼加強化處理的母線槽，具有美觀、耐久、剛度高、承載力大等長處；選用吊架，加大了吊架與母線之間的觸摸面積，裝置工藝簡潔，銜接可靠。可以增大吊架的水平距離，削減吊架及母線槽接頭的數(shù)量，節(jié)省成本費用。

The construction scheme uses the bus duct with shell and strengthening treatment, which has the advantages of beauty, durability, high rigidity, large bearing capacity and so on; The hanger is selected to increase the touch area between the hanger and the bus. The device process is simple and the connection is safe and reliable. It can increase the horizontal distance of hangers, reduce the number of hangers and bus duct joints, and save costs.

本方案適用于大部分樓層頂棚處的母線槽裝置施工。加強型母線槽為工廠定制，生產(chǎn)時在母線槽外殼進行加肋強化處理，進步殼身的慣性矩和抗扭矩，可在不增加殼身板材厚度的情況下大幅度進步整個母線槽的承載能力。

This scheme is applicable to the construction of bus duct device at the ceiling of most floors. The reinforced bus duct is customized in the factory. During production, the bus duct shell is stiffened and strengthened to improve the inertia moment and torque resistance of the shell, which can greatly improve the bearing capacity of the whole bus duct without increasing the thickness of the shell plate.

濟南電纜橋架廠家認為選用的吊架可重復利用的附加有鋼板的吊架裝置固定母線槽，加寬了吊架與母線槽的觸摸面積，可增加吊架的裝置距離，削減母線槽接頭數(shù)量，削減材料的用量。

Jinan cable tray manufacturer believes that the selected hangers can be reused, and the hanger device with steel plate attached can fix the bus duct, which widens the touch area between the hanger and the bus duct, increases the device distance of the hanger, reduces the number of bus duct joints, and reduces the amount of materials.
