Pallet cable bridge is widely used in petroleum, chemical industry, light industry, television, telecommunications and other fields. It has the advantages of light weight, large load, beautiful shape, simple structure and convenient installation. It is not only suitable for the installation of power cable, but also suitable for the laying of control cable. Next, our cable bridge manufacturers will introduce to you the main points of tray cable bridge selection, hoping to help you all! ____________

1.在选择电缆桥架的荷载等级时，电缆桥架的工作均布荷载不应大于所选电缆桥架荷载等级的额定均布荷载，如果电缆桥架的支吊架的实际跨距不等于2m时，则工作均布荷载应满足要求。

1. When choosing the load grade of the cable bridge, the working uniform load of the cable bridge should not be greater than the rated uniform load of the load grade of the selected cable bridge. If the actual span of the suspension of the cable bridge is not equal to 2 m, the working uniform load should meet the requirements.

2.在工程防火要求较高的场所，不宜采用铝合金电缆桥架。

2. Aluminum alloy cable bridge should not be used in places with high fire protection requirements.

3.电缆桥架、线槽及其支吊架使用在有腐蚀性环境中，应采用耐腐蚀的刚性材料制造，或采取防腐蚀处理，防腐蚀处理方式应满足工程环境和耐久性的要求。

3. Cable bridges, grooves and their support and hangers should be made of corrosion-resistant rigid materials in corrosive environments or be treated with corrosion protection, which should meet the requirements of engineering environment and durability.

4.电缆梯架、托盘宽度和高度的选择应符合填充率的要求，电缆的梯架和托盘内的填充率在一般情况下，电力电缆可取40%～50%，控制电缆可取50%～70%，且宜预留10%～25%工程发展裕量。

4. The selection of cable ladder, tray width and height should meet the requirement of filling rate. In general, the filling rate in cable ladder and tray can be 40%-50% for power cable, 50%-70% for control cable, and 10%-25% for engineering development margin should be reserved.

5.各种组件及支吊架在满足相应荷载的条件下，其规格尺寸应与托盘、梯架的直线段、弯通系列相匹配。

5. The specifications and sizes of various components and supports and hangers should be matched with the straight sections of pallets, ladders and bending-through series under the conditions of meeting the corresponding loads.

6.电缆桥架在有防火要求的区段内，可在电缆梯架、托盘内添加具有耐火或难燃性能的板、网等材料构成封闭或半封闭式结构，并采取在桥架及其支吊架表面涂刷防火涂层等措施，其整体耐火性能应满足有关规范或标准的要求。

6. In the section with fire protection requirements, the cable bridge can be enclosed or semi-enclosed by adding fire-resistant or flame-retardant materials such as boards and nets to the cable ladder and tray. Measures such as coating fire-resistant coatings on the surface of the bridge and its support and hanger should be taken. The overall fire resistance of the cable bridge should meet the requirements of relevant national standards or standards.

7.在选择电缆桥架的弯通或引上、引下装置时，不应小于电缆桥架内电缆小允许弯曲半径。

7. The minimum allowable bending radius should not be less than the minimum allowable bending radius of the cables in the cable bridge when choosing the bending or pulling-up and pulling-down devices of the cable bridge.

8.几组电缆桥架在同一高度平行敷设时，各相邻电缆桥架之间应考虑维护、检修距离。

8. When several groups of cable bridges are laid parallel at the same height, the maintenance and repair distances between adjacent cable bridges should be considered.

9.对于跨距大于6m的钢制电缆桥架和跨距大于2m或承载要求大于荷载等级D级的铝合金电缆桥架，应按工程条件进行强度、刚度及稳定性的计算或试验验证。

9. Strength, stiffness and stability of steel cable bridge with span greater than 6 m and aluminium alloy cable bridge with span greater than 2 m or bearing requirement greater than load grade D should be calculated or tested according to engineering conditions.
