電纜橋架在電纜鋪設(shè)工程中發(fā)揮著基本功能。對于高壓的電力電纜，我們應(yīng)根據(jù)不同的用電場景，選擇不同的電纜橋架。由此可見，室外控制電纜，配線電纜，室內(nèi)電纜等不同的場景需要選型不同的濟(jì)南橋架。

Cable tray plays a basic role in cable laying engineering. For high-voltage power cables, we should select different cable trays according to different power consumption scenarios. It can be seen that different Jinan bridges need to be selected for different scenarios such as outdoor control cables, distribution cables and indoor cables.

電纜橋架因為其本身的特性，類型多，應(yīng)用方面極廣，結(jié)構(gòu)設(shè)計嚴(yán)謹(jǐn)，實惠，深受工程師喜歡。但是橋架有著諸多的分類，讓人頭疼。從形式上看，有托盤，梯級，組合和槽式的形式，根據(jù)安裝形式的不同，選擇不同的橋架。

Because of its own characteristics, many types, wide application, rigorous structural design and affordable price, cable trays are popular with engineers. However, there are many types of bridges, which make people headache. From the perspective of form, there are tray, step, combination and trough forms, and different bridges are selected according to different installation forms.

重要的是表面做過處理的橋架，各有各的優(yōu)點和用處。冷鍍鋅電纜橋架，經(jīng)過酸洗，表面光滑均勻。熱鍍鋅電纜橋架可以起到防腐的作用，用于室外。熱噴鋅涂層硬度強(qiáng)大，不會因外力而變形。不同類型的橋架應(yīng)該適用于不同的環(huán)境。

The important thing is that the bridge with surface treatment has its own advantages and uses. The cold galvanized cable tray has a smooth and uniform surface after acid cleaning. The hot-dip galvanized cable tray can play the role of corrosion protection and is used outdoors. The thermal sprayed zinc coating has strong hardness and will not be deformed due to external force. Different types of bridges should be suitable for different environments.

電纜橋架的規(guī)格選擇：

Specification selection of cable tray:

1、電纜橋架的寬度和高度就按下表選擇，并應(yīng)符合電纜填充率不超過有關(guān)標(biāo)準(zhǔn)規(guī)范的規(guī)定值，動力電纜可取40-50%，控制電纜可取50-70%，另外需予留10-25%的式程發(fā)展余量。

1. The width and height of the cable tray shall be selected according to the following table, and the cable filling rate shall not exceed the specified value of the relevant standards and specifications. The power cable can be 40-50%, the control cable can be 50-70%, and 10-25% type development margin shall be reserved.

2、各種彎通及附件規(guī)格應(yīng)符合工程布置條件并與橋架相配套。

2. The specifications of various bends and accessories shall meet the engineering layout conditions and be matched with the bridge.

3、支、吊架規(guī)格的選擇，應(yīng)按橋架規(guī)格、層數(shù)、跨距等條件配置。并應(yīng)滿足荷載的要求。

3. The specifications of supports and hangers shall be selected according to the specifications, layers, spans and other conditions of the bridge. And shall meet the requirements of load.

此外電纜橋架一定要注意對外界電磁干擾要有很好的屏蔽作用，由于一些特殊的工作環(huán)境，就要求電纜橋架的設(shè)計一定要有抗強(qiáng)腐蝕性的能力。

In addition, the cable bridge must be well shielded from external electromagnetic interference. Due to some special working environment, the design of the cable bridge must be able to resist strong corrosion.

由于電纜橋架是金屬構(gòu)件，所以要有非常良好的接地。還需要使用防火性能強(qiáng)的材料加以制作。電纜橋架的設(shè)計不僅要注重外表的美觀，重要的是一定要保證使用者的。關(guān)注我們http://m.ymmgjx.net，帶您了解更多事項！

As the cable tray is a metal component, it should be well grounded. It also needs to be made of materials with strong fire resistance. The design of cable bridge should not only pay attention to the appearance of beauty, but also ensure the safety of users. Follow us http://m.ymmgjx.net , take you to learn more!
