桥架是一个支撑和放电缆的支架。桥架在工程上用的很普遍，只要铺设电缆就要用桥架，电缆桥架作为布线工程的一个配套项目。线槽又名走线槽、配线槽、行线槽（因地方而异），用来将电源线、数据线等线材规范的整理，固定在墙上或者天花板上的电工用具。一般有塑料材质和金属材质两种，可以起到不同的作用。下面 山东电缆桥架厂家来讲讲桥架和线槽两者的具体区别。

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.

尺寸规格有所不同。桥架相对大（200×100到600×200)，线槽相对较小。若电缆电线比较多，建议用桥架。

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。根据JGJ16-2008-5.1金属线槽也称槽式桥架，一般由0.4-1.5mm厚的整张钢板弯制而成的槽型部件，概念上与桥架区别是高、宽比不同，盘架浅而宽，金属线槽是具有一定的深度和封闭性。但是桥架比线槽更加结实，更多的用来放电缆，当然也可以放电线，通常是强电系统用。

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。根据JGJ16-20088.5.3，线槽内电线电缆的总截面不应超过线槽内截面的20%，载流导体不超过30根，而桥架是电缆的总截面不应超过截面的40%。这是由于安装高度不同所致，安装高度较低必须有盖板，有盖板散热不好，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。金属线槽密封较好，不一定要支架支撑，可以在电缆沟和建筑夹层中敷设。槽式桥架有些是半敞开式的，一定要有支架做支撑，在屋内或屋外一般沿空中架设。

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.

强度不同。桥架主要用于敷设电力电缆和控制电缆，线槽的强度较低，通常用于敷设导线和通讯线缆，比如网络电话等。

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.

拐弯半径不同。桥架拐弯半径比较大，线槽大部分拐直角弯。

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。桥架跨距比较大，线槽比较小。因此固定支架差别较大，支吊架的个数差别大。

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.

支吊架间距不同。根据JGJ16-2008，线槽为不大于2m，桥架为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.

安装方式不同。桥架有专门规范，而线槽无专门规范固定。

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