大跨距电缆桥架通常是指一米或四米以上，并且桥梁的厚度是根据标准来实现的。由于其屏蔽干扰和控制电缆上的重负荷而适用于铺设计算机电缆，通信电缆和其他高灵敏度系统控制电缆等。 山东电缆桥架厂家认为，选择江南体育移动端app官网 时应注意8个要素！

Long span cable tray usually refers to one meter or more, and the thickness of the bridge is realized according to the standard. It is suitable for laying computer cables, communication cables and other high sensitivity system control cables due to its shielding interference and heavy load on control cables. Shandong cable tray manufacturer believes that 8 elements should be paid attention to when selecting long-span cable tray!

1）在腐蚀性环境中使用时，电缆桥架，线槽及其支撑和吊架应使用耐腐蚀的硬质材料制成，或者应采用防腐蚀处理。防腐处理方法应符合工程环境和耐久性要求。

1) When used in corrosive environment, cable tray, trunking and its supports and hangers shall be made of corrosion-resistant hard materials, or anti-corrosion treatment shall be adopted. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability.

2）对于具有防火要求的部分的电缆桥架，可以在大跨距电缆桥架中添加耐火或不易燃的板，网和其他材料以形成封闭或半封闭的结构，并用于桥梁和支撑物机架表面应涂防火涂料，其总体耐火性应符合相关法规或标准的要求。

2) For the cable tray with fire protection requirements, fire-resistant or non flammable plates, nets and other materials can be added to the long-span cable tray to form a closed or semi closed structure, and the surface of the bridge and support frame shall be coated with fire-resistant paint, and its overall fire resistance shall meet the requirements of relevant regulations or standards.

3）铝电缆桥架不应在对工程防火要求较高的地方使用。

3) Aluminum cable tray shall not be used in places with high fire protection requirements for the project.

4）电缆梯架和桥架的宽度和高度的选择应满足填充率的要求。通常，电缆梯架和桥架的填充率对于电力电缆可以为40％-50％，对于控制电缆可以为50％?70。％，并且应保留项目开发利润的10％-25％。

4) The width and height of cable ladder and tray shall meet the requirements of filling rate. Generally, the filling rate of cable ladders and trays can be 40% - 50% for power cables and 50% for control cables? 70。％， And 10% - 25% of the project development profit shall be retained.

5）选择电缆桥架的载荷水平时，电缆桥架的工作均匀载荷不应大于所选电缆桥架载荷水平的额定均匀载荷。如果电缆桥架的支架和吊架的实际跨度不等于2m，则均匀的工作负荷应满足要求。

5) When selecting the load level 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 level. If the actual span of the support and hanger of the cable tray is not equal to 2m, the uniform working load shall meet the requirements.

6）在各种部件，大跨距电缆桥架满足相应的载荷条件的情况下，其规格和尺寸应与托盘和梯子的直截面和弯头系列相匹配。

6) When various components and long-span cable bridges meet the corresponding load conditions, their specifications and dimensions shall match the straight section and elbow series of trays and ladders.

7）选择电缆桥架的弯曲或上下引导装置时，其长度不应小于电缆桥架中电缆的允许弯曲半径。

7) When selecting the bending or upper and lower guiding device of cable tray, its length shall not be less than the allowable bending radius of cables in cable tray.

8）对于跨度大于6m的钢制电缆桥架和跨度大于2m的铝合金电缆桥架或大于D级载荷的承重要求，应根据工程条件计算或测试其强度，刚度和稳定性。

8) The strength, stiffness and stability of the steel cable tray with a span of more than 6m and the aluminum alloy cable tray with a span of more than 2m or the load bearing requirements of more than Class D shall be calculated or tested according to the engineering conditions.

9）当几组电缆桥架以相同高度平行放置时，应考虑相邻电缆桥架之间的维护和维修距离。

9) When several groups of cable trays are placed in parallel at the same height, the maintenance and repair distance between adjacent cable trays shall be considered.
