托盘式桥架是由托盘或梯架的直线段、弯通、组件以及托臂（臂式支架）、吊架等构成具有密接支承电缆的刚性结构系统之全称。下面就跟着 山东电缆桥架厂家一起来了解下托盘式桥架产品选用要点吧。

Tray type bridge is the full name of the rigid structure system with closely connected supporting cables, which is composed of straight sections, bends, components of trays or ladders, brackets (arm supports), hangers, etc. Let's follow the Shandong cable tray manufacturers to understand the key points of the selection of tray type cable tray products.

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。

Cable trays, trunking and their supports and hangers used in corrosive environment shall be made of corrosion-resistant rigid materials or treated with anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability.

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。

In the section with fire protection requirements, the cable tray can be added with plates, nets and other materials with fire-resistant or flame-retardant properties in the cable ladder and tray to form a closed or semi closed structure, and measures such as painting fire-resistant coating on the surface of the cable tray and its supports and hangers shall be taken. The overall fire resistance performance shall meet the requirements of relevant national codes or standards.

在工程防火要求较高的场所，不宜采用铝合金电缆桥架。

In places with high fire protection requirements, aluminum alloy cable trays should not be used.

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，控制电缆可取50%～70%，且宜预留10%～25%工程发展裕量。

The width and height of cable ladder and tray shall meet the requirements of filling rate. Generally, the filling rate of cable ladder and tray is 50% ~ 70% for power cable and 50% ~ 25% for control cable, and 10% ~ 25% for project development should be reserved.

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。

When selecting the load grade of the cable tray, the working uniform load of the cable tray shall not be greater than the rated uniform load of the selected cable tray load grade. If the actual span of the supports and hangers of the cable tray is not equal to 2m, the working uniform load shall meet the requirements.

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。

Under the condition that various components and supports and hangers meet the corresponding loads, their specifications and dimensions shall match with the straight section and bend series of trays and ladders.

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。

When selecting the bend through or lead-in and lead-down devices of the cable tray, it shall not be less than the small allowable bending radius of the cable in the cable tray.

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。

For steel cable trays with a span of more than 6m and aluminum alloy cable trays with a span of more than 2m or a bearing requirement greater than the load grade D, the strength, rigidity and stability shall be calculated or tested according to the engineering conditions.
