电缆桥架主要是用来敷设电缆线路的，而金属线槽主要敷设电线导线的。两者的材质也是不一样的，桥架一般用的材质是冷轧钢板，而线槽却是用热轧钢板。金属线槽跟槽式电缆桥架形状是一样的，只不过金属线槽的尺寸就稍微小了一点和材质性能有差距。下面跟着 济南电缆桥架厂家来了解更多相关内容吧。

The cable tray is mainly used for laying cable lines, while the metal trunking is mainly used for laying wires. The materials of the two are also different. The bridge is generally made of cold-rolled steel plate, while the trunking is made of hot-rolled steel plate. The shape of the metal trunking is the same as that of the trough type cable tray, but the size of the metal trunking is slightly smaller and there is a gap between the material performance. Let's follow the Jinan cable tray manufacturer to learn more about it.

金属线槽和桥架的区别金属线槽宽度一般小于200mm，而电缆桥架一般则大于200mm。金属线槽主要用于敷设导线。桥架主要用于敷设电缆。金属线槽就只有一种，一般用热轧钢板制作而成。电缆桥架敷设的时候一般应该考虑其载荷、扰度、填充率等等。

Difference between metal trunking and cable tray: the width of metal trunking is generally less than 200mm, while that of cable tray is generally greater than 200mm. Metal trunking is mainly used for laying conductors. The bridge is mainly used for laying cables. There is only one kind of metal trunking, which is generally made of hot-rolled steel plate. When laying cable tray, its load, disturbance, filling rate, etc. shall be generally considered.

金属线槽大致等于草食电缆桥架，知识有一些金属线槽的尺寸要小一些而已。两种敷设方式、在流量不同。金属线槽一般用的是镀锌铁皮，而桥架则一般为冷轧钢板。如果从外观看的话金属线槽比较的后，安装比较牢固。

The metal trunking is roughly equal to the herbivorous cable tray. Some knowledge shows that the size of the metal trunking is smaller. The two laying methods are different in flow. Galvanized iron sheet is generally used for metal trunking, and cold-rolled steel plate is generally used for bridge. From the appearance, the metal trunking is relatively smooth and the installation is relatively firm.

在材质上也有很大的区分。

There are also great differences in material.

金属线槽应平整、无扭曲变形，内壁应光滑、无毛刺。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。

The metal trunking shall be flat without distortion and deformation, and the inner wall shall be smooth without burr. When the metal trunking is installed vertically or obliquely, measures shall be taken to prevent the wires or cables from moving in the trunking.

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。

All phase wires and neutral wires of the same circuit shall be laid in the same metal trunking. Lines with no anti-interference requirements on the same path can be laid in the same metal trunking. The total section (including the outer sheath) of wires or cables in the trunking shall not exceed 20% of the section in the trunking, and the number of current carrying wires 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.

金属线槽应可靠接地或接零，但不应作为设备的接地导体。

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

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。

The lines led out from the metal trunking can be wired by metal pipes, hard plastic pipes, semi hard plastic pipes, metal hoses or cables. Wires or cables shall not be damaged at the outgoing part.

电缆桥架金属线槽安装要求线槽的规格尺寸、组装方式和安装位置均应按设计规定和施工图的要求。线缆桥架底部应高于地面2.2m及以上，顶部距建筑物楼板不宜小于300mm，与梁及其他妨碍物交叉处间的距离不宜小于50mm。

The specification, size, assembly method and installation position of the cable tray metal trunking shall be in accordance with the design regulations and the requirements of the construction drawings. The bottom of the cable tray shall be 2.2m and above the ground, the distance between the top and the building floor shall not be less than 300mm, and the distance between the intersection with the beam and other obstacles shall not be less than 50mm.

电缆桥架水平敷设时，支撑间距宜为1.5～3m。垂直敷设时，固定在建筑物结构体上的间距宜小于2m，距地1.8m以下部分应加金属盖板保护或采用金属走线柜包封，门应可开启。等等。

When the cable tray is laid horizontally, the support spacing should be 1.5-3m. When laying vertically, the distance fixed on the building structure should be less than 2m. The part below 1.8m from the ground should be protected by metal cover plate or enclosed by metal wiring cabinet, and the door should be openable. wait.
