电缆桥架在电缆铺设工程中发挥着基本功能。对于高压的电力电缆，我们应根据不同的用电场景，选择不同的电缆桥架。由此可见，室外控制电缆，配线电缆，室内电缆等不同的场景需要选型不同的 江南app官方入口在哪里看到。

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.

电缆桥架因为其本身的特性，类型多，应用方面极广，结构设计严谨，价格实惠，深受工程师喜欢。但是桥架有着诸多的分类，让人头疼。从形式上看，有托盘，梯级，组合和槽式的形式，根据安装形式的不同，选择不同的桥架。

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.

重要的是表面做过处理的桥架，各有各的优点和用处。冷镀锌电缆桥架，经过酸洗，表面光滑均匀。热镀锌电缆桥架可以起到防腐的作用，用于室外。热喷锌涂层硬度强大，不会因外力而变形。不同类型的桥架应该适用于不同的环境。

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.

电缆桥架的规格选择：

Specification selection of cable tray:

1、电缆桥架的宽度和高度就按下表选择，并应符合电缆填充率不超过有关标准规范的规定值，动力电缆可取40-50%，控制电缆可取50-70%，另外需予留10-25%的式程发展余量。

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、各种弯通及附件规格应符合工程布置条件并与桥架相配套。

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

3、支、吊架规格的选择，应按桥架规格、层数、跨距等条件配置。并应满足荷载的要求。

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.

此外电缆桥架一定要注意对外界电磁干扰要有很好的屏蔽作用，由于一些特殊的工作环境，就要求电缆桥架的设计一定要有抗强腐蚀性的能力。

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.

由于电缆桥架是金属构件，所以要有非常良好的接地。还需要使用防火性能强的材料加以制作。电缆桥架的设计不仅要注重外表的美观，重要的是一定要保证使用者的安全。关注我们 //www.comprepyme.com，带您了解更多事项！

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 //www.comprepyme.com , take you to learn more!
