电缆桥架分为槽型、托盘型、梯型、网孔型等结构，由支架、支撑臂和安装附件组成。建筑物内的桥架可独立架设，也可附接于各种建筑物（构筑物）和管廊支架上。应体现结构简单、外形美观、配置灵活、维修方便等特点。所有零件都需要镀锌，安装在建筑物外的露天桥上。那么您知道桥架90度弯头制作的方法和桥架选择是怎样的吗？

Cable trays are divided into trough type, tray type, ladder type, mesh type and other structures, which are composed of supports, support arms and installation accessories. The bridge in the building can be erected independently or attached to various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, convenient maintenance, etc. All parts need to be galvanized and installed on the open bridge outside the building. Do you know how to make the 90 degree elbow of the bridge and how to choose the bridge?

桥架90度弯头的制作方法：将桥架中段底板剪成等腰梯形，连接等腰梯形底板的桥架两侧为长方形，然后互换左右两端的桥架，分别与中间的一座。一段桥对接，焊接固定。电缆桥架分为槽型、托盘型、梯型、网孔型等结构，由支架、支撑臂和安装附件组成。桥架的选择。

Fabrication method of 90 degree elbow of bridge: cut the middle bottom plate of the bridge into isosceles trapezoid, the two sides of the bridge connecting the isosceles trapezoid bottom plate are rectangular, and then exchange the bridges at the left and right ends with one in the middle respectively. One section of the bridge is butt welded and fixed. Cable trays are divided into trough type, tray type, ladder type, mesh type and other structures, which are composed of supports, support arms and installation accessories. Selection of bridge.

桥架的选择

Selection of bridge

1、在工程设计中，应根据经济合理性、技术可行性、运行安全性等因素综合比较桥架的布置方案，确定佳方案，充分满足施工、安装、维护和保养的要求。电缆铺设。

1. In the engineering design, the layout scheme of the bridge shall be comprehensively compared according to the economic rationality, technical feasibility, operation safety and other factors, and the best scheme shall be determined to fully meet the requirements of construction, installation, maintenance and maintenance. Cable laying.

2、桥架水平敷设时，离地高度一般不小于2.5m。垂直敷设时，离地1.8m以下的部分应有金属罩保护，但敷设在电气室时除外。如果电缆桥架水平敷设在设备夹层或马道上且低于2.5m，应采取保护接地措施。

2. When the bridge is laid horizontally, the height from the ground is generally not less than 2.5m. When laying vertically, the part below 1.8m above the ground shall be protected by a metal cover, except when laying in the electrical room. If the cable tray is horizontally laid on the equipment interlayer or Packway and is less than 2.5m, protective grounding measures shall be taken.

3、 山东电缆桥架、线槽及其支吊架用于腐蚀性环境，应采用耐腐蚀的刚性材料。或采取防腐处理，防腐处理方式应符合工程要求。

3. Shandong cable tray, trunking and its supports and hangers are used in corrosive environment and should be made of corrosion-resistant rigid materials. Or adopt anti-corrosion treatment, and the anti-corrosion treatment method shall meet the engineering requirements.

此外，对于耐腐蚀或清洁度要求较高的场所，宜选用铝合金电缆桥架。更多关于桥架的相关事项，您可以来我们网站 //www.comprepyme.com进行咨询！

In addition, for places with high requirements for corrosion resistance or cleanliness, aluminum alloy cable trays should be selected. For more information about bridge, you can come to our website //www.comprepyme.com Consult!
