托盘式电缆桥架、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。

Tray type cable trays, cable trays, and their supports and hangers should be made of corrosion-resistant rigid materials or treated with anti-corrosion measures when used in corrosive environments. The anti-corrosion treatment method should meet the requirements of the 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国家有关规范或规范的要求。

In sections with fire protection requirements, cable trays can be equipped with fire-resistant or flame-retardant plates, nets, and other materials in cable ladders and trays to form closed or semi closed structures. Methods such as applying fire-resistant coatings on the surface of cable trays and their supports and hangers should be adopted, and their overall fire resistance function should meet the requirements of relevant national regulations or norms.

在工程防火要求较高的场所，不宜选用铝合金电缆桥架。

Aluminum alloy cable trays should not be used in places with high fire prevention requirements.

电缆梯架、托盘宽度和高度的挑选应契合填充率的要求，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%，操控电缆可取50%～70%，且宜预留10%～25%工程开展裕量。

The selection of cable ladder and tray width and height should meet the requirements of filling rate. In general, the filling rate inside the cable ladder and tray can be 40% to 50% for power cables and 50% to 70% for control cables, and a 10% to 25% engineering allowance should be reserved.

在挑选电缆桥架的荷载等级时，电缆桥架的作业均布荷载不该大于所选电缆桥架荷载等级的额外均布荷载，假如电缆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。

When selecting the load level of cable tray, the uniformly distributed load of the cable tray should not exceed the additional uniformly distributed load of the selected cable tray load level. If the practical span of the support and hanger of the cable tray is not equal to 2m, the uniformly distributed load of the operation should meet the requirements.

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

Under satisfactory load conditions, the standard dimensions of various components and support hangers should match the straight sections and bending series of pallets and ladders.

在挑选电缆桥架的弯通或引上、引下设备时，不该小于电缆桥架内电缆非常小答应曲折半径。

When selecting cable tray bends or equipment for leading up and down, the minimum allowable bending radius of the cables inside the cable tray should not be less than.

关于跨距大于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、刚度及稳定性的核算或实验验证。

For steel cable trays with a span greater than 6m and aluminum alloy cable trays with a span greater than 2m or load-bearing requirements greater than load level D, the strength, stiffness, and stability should be calculated or experimentally verified according to the engineering conditions.

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保护、检修间隔。

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