橋架是一個支撐和放電纜的支架。橋架在工程上用的很普遍，只要鋪設電纜就要用橋架，電纜橋架作為布線工程的一個配套項目。線槽又名走線槽、配線槽、行線槽（因地方而異），用來將電源線、數據線等線材規范的整理，固定在墻上或者天花板上的電工用具。一般有塑料材質和金屬材質兩種，可以起到不同的作用。下面山東電纜橋架廠家來講講橋架和線槽兩者的具體區別。

The bridge is a support for supporting and placing cables. Cable trays are widely used in engineering. As long as cables are laid, cable trays should be used. Cable trays are used as a supporting project of wiring engineering. The trunking is also known as the wiring trough, wiring trough, and line trunking (depending on the location). It is used to sort out the specifications of power lines, data lines, and other wires, and to fix the electrical appliances on the wall or ceiling. Generally, there are plastic materials and metal materials, which can play different roles. Next, Shandong cable tray manufacturer will talk about the specific differences between cable tray and trunking.

尺寸規格有所不同。橋架相對大（200×100到600×200)，線槽相對較小。若電纜電線比較多，建議用橋架。

The size specifications are different. The bridge is relatively large (200 × 100 to 600 × 200), the trunking is relatively small. If there are many cables and wires, it is recommended to use bridge.

材料厚度不同。根據JGJ16-2008-5.1金屬線槽也稱槽式橋架，一般由0.4-1.5mm厚的整張鋼板彎制而成的槽型部件，概念上與橋架區別是高、寬比不同，盤架淺而寬，金屬線槽是具有一定的深度和封閉性。但是橋架比線槽更加結實，更多的用來放電纜，當然也可以放電線，通常是強電系統用。

The material thickness is different. According to JGJ16-2008-5.1, metal trunking is also known as trough-type cable tray. It is generally a trough-type component made of 0.4-1.5mm thick whole steel plate. Conceptually, it is different from the cable tray in terms of height and width ratio. The tray frame is shallow and wide. The metal trunking has a certain depth and closure. However, the cable tray is more solid than the trunking. It is more used to place cables, and of course, it can also place wires, usually for strong current systems.

填充率不同。根據JGJ16-20088.5.3，線槽內電線電纜的總截面不應超過線槽內截面的20%，載流導體不超過30根，而橋架是電纜的總截面不應超過截面的40%。這是由于安裝高度不同所致，安裝高度較低必須有蓋板，有蓋板散熱不好，填充率就要小一些。

The filling rate is different. According to JGJ16-20088.5.3, the total cross-section of wires and 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, while the total cross-section of the cable tray shall not exceed 40% of the cross-section. This is due to the different installation height. The lower installation height must have a cover plate. If the cover plate has bad heat dissipation, the filling rate will be lower.

密封性不同。金屬線槽密封較好，不一定要支架支撐，可以在電纜溝和建筑夾層中敷設。槽式橋架有些是半敞開式的，一定要有支架做支撐，在屋內或屋外一般沿空中架設。

The tightness is different. The metal trunking is well sealed and can be laid in cable trench and building interlayer without support. Some trough-type bridges are semi-open and must be supported by brackets, which are generally erected in the air inside or outside the house.

強度不同。橋架主要用于敷設電力電纜和控制電纜，線槽的強度較低，通常用于敷設導線和通訊線纜，比如網絡電話等。

Different strength. The cable tray is mainly used for laying power cables and control cables. The strength of the trunking is low, and it is usually used for laying wires and communication cables, such as network telephone.

拐彎半徑不同。橋架拐彎半徑比較大，線槽大部分拐直角彎。

The turning radius is different. The turning radius of the bridge is relatively large, and most of the trunking turns at right angles.

跨距不同。橋架跨距比較大，線槽比較小。因此固定支架差別較大，支吊架的個數差別大。

The span is different. The bridge span is relatively large, and the trunking is relatively small. Therefore, the number of fixed supports and hangers varies greatly.

支吊架間距不同。根據JGJ16-2008，線槽為不大于2m，橋架為1.5~3m。

The spacing between supports and hangers is different. According to JGJ16-2008, the trunking is no more than 2m and the bridge is 1.5~3m.

安裝方式不同。橋架有專門規范，而線槽無專門規范固定。

Different installation methods. The cable tray has special specifications, while the trunking is fixed without special specifications.
