(1)金属线槽布线搬适用于正常环境的室内干燥和不易受机械损伤的场所明敷,但对金属线槽有严重腐蚀的场所不应采用。
(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)同一回路的所有相线和中性线,应敷设在同一金属线槽内。同一路径无防干扰要求的线路,可敷设于同一金属线槽内,线槽内电线或电缆的总截面(包括外护层)不应超过线槽内截面的20%,载流导线不宜超过30根。控制、信号或与其相类似的线路,电线或电缆的总截向下应超过线槽内截面的50%,电线或电缆根数下限。
(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)电缆桥架金属线槽垂直或倾斜安装时,应采取措施防止电线或电缆在线槽内移动。
(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)由金属线槽引出的线路,可采用金属管,硬质塑料管、半硬塑料管、金属软管或电缆等布线方式。电线或电缆在引出部分不得遭受损伤。
(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)线糟应平整、无扭曲变形,内壁应光滑、无毛刺。
(5) The wire slot shall be flat without distortion and deformation, and the inner wall shall be smooth without burrs.
(6)电缆桥架金属线槽应可靠接地或接零,但不应作为设备的接地导体。
(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壳加强化处理的母线槽,具有美观、耐久、刚度高、承载力大等长处;选用吊架,加大了吊架与母线之间的触摸面积,装置工艺简洁,衔接安全可靠。可以增大吊架的水平距离,削减吊架及母线槽接头的数量,节省成本费用。
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.
本方案适用于大部分楼层顶棚处的母线槽装置施工。加强型母线槽为工厂定制,生产时在母线槽外壳进行加肋强化处理,进步壳身的惯性矩和抗扭矩,可在不增加壳身板材厚度的情况下大幅度进步整个母线槽的承载能力。
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.
济南电缆桥架厂家认为选用的吊架可重复利用的附加有钢板的吊架装置固定母线槽,加宽了吊架与母线槽的触摸面积,可增加吊架的装置距离,削减母线槽接头数量,削减材料的用量。
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.
