梯级式电缆桥架备有护罩，需求配护罩时可在订购时注明，其所有配件与托盘式、槽式桥架通用。在梯式桥架的使用过程中，有诸多的注意事项需要大家注意，下面 山东电缆桥架厂家为您解说。

Ladder type cable tray is equipped with shield, which can be noted when ordering, and all its accessories are common to tray type and trough type cable tray. In the process of using ladder type cable tray, there are many precautions that should be paid attention to. Below, Shandong cable tray manufacturer will explain them to you.

1、桥架、线槽及其支吊架运用在有腐蚀性环境中，应选用耐腐蚀的刚性资料制作，或采纳防腐蚀处理，防腐蚀处理方式应满意工程环境和耐久性的要求。

1. When bridge, trunking and its supports and hangers are used in corrosive environment, they shall be made of corrosion-resistant rigid materials, or adopt anti-corrosion treatment, which shall meet the requirements of engineering environment and durability.

2、桥架在有防火要求的区段内，可在电缆梯架、托盘内增加具有耐火或难燃功能的板、网等资料构成关闭或半关闭式结构，并采纳在桥架及其支吊架外表涂刷防火涂层等办法，其全体耐火功能应满意有关规范或规范的要求。

2. In the section with fire protection requirements, the cable ladder and tray can be added with plates, nets and other materials with fire resistance or flame retardant functions to form a closed or semi closed structure, and the method of painting fire retardant coating on the surface of the bridge and its supports and hangers shall be adopted. All the fire resistance functions shall meet the requirements of relevant specifications or specifications.

3、在工程防火要求较高的场所，不宜选用铝合金桥架。

3. In places with high fire protection requirements, aluminum alloy bridge should not be used.

4、电缆梯架宽度和高度的挑选应契合填充率的要求，电缆的梯架的填充率在一般情况下，电力电缆可取40%～50%，操控电缆可取50%～70%，且宜预留10%～25%工程开展裕量。

4. The selection of cable ladder width and height shall meet the requirements of filling rate. In general, the filling rate of cable ladder can be 40%~50% for power cables, 50%~70% for control cables, and 10%~25% for project development should be reserved.

5、在挑选电缆梯架的荷载等级时，桥架的作业均布荷载不该大于所选桥架荷载等级的额外均布荷载，假如桥架的支吊架的实践跨距不等于2m时，则作业均布荷载应满意要求。

5. When selecting the load level of the cable ladder, the operating uniform load of the bridge should not be greater than the additional uniform load of the selected bridge load level. If the practical span of the bridge's supports and hangers is not equal to 2m, the operating uniform load should meet the requirements.

6、各种组件及支吊架在满意相应荷载的条件下，其标准尺度应与托盘、梯架的直线段、弯通系列相匹配

6. Under the condition of satisfying the corresponding load, the standard dimensions of various components, supports and hangers shall match with the straight sections and bending series of trays and ladders

7、在挑选桥架的弯通或引上、引下设备时，不该小于桥架内电缆小答应曲折半径。

7. When selecting the bending or leading up and down equipment of the bridge, it should not be less than the allowable bending radius of the cable in the bridge.

8、关于跨距大于6m的钢制桥架和跨距大于2m或承载要求大于荷载等级D级的铝合金桥架，应按工程条件进行强度、刚度及稳定性的核算或实验验证。

8. For steel bridges with a span greater than 6m and aluminum alloy bridges with a span greater than 2m or a bearing requirement greater than load level D, the strength, stiffness and stability shall be calculated or verified by experiments according to the engineering conditions.

9、几组桥架在同一高度平行敷设时，各相邻电缆桥架之间应考虑保护、检修间隔。

9. When several groups of cable trays are laid in parallel at the same height, protection and maintenance intervals shall be considered between adjacent cable trays.
