山东电缆桥架作为保护电缆的产品,一直被应用,它的类型也比较多,有梯式桥架、槽式桥架、有孔托盘式桥架等。桥架既可独立架设安装,全部零件均需进行镀锌处理,可安装在建筑物外露天,也可以敷设在建筑物和管廊支架上。
ShandongAs a product for protecting cables, cable trays have been used all the time. There are many types of cable trays, such as ladder trays, trough trays, and perforated tray trays. The bridge can be erected and installed independently, and all parts need to be galvanized. It can be installed in the open air outside the building, or laid on the building and the pipe gallery bracket.
在很多需要保护裸露电线的供电环境中,如地下停车场、厂房等,都可以看到电缆桥架的应用。
In many power supply environments where exposed wires need to be protected, such as underground parking lots, workshops, etc., the application of cable trays can be seen.
1.腐蚀环境中使用的电缆桥架、线槽及其支吊架应采用选取耐腐蚀硬质材料或经过防腐处理,应满足工程环境和耐久性的要求。
1. Cable trays, trunkings and their supports and hangers used in corrosive environments should be made of corrosion-resistant hard materials or undergo anti-corrosion treatment, which should meet the requirements of engineering environment and durability.
2.电缆桥架需防火的地段,可在电缆梯架和桥架内加入具有耐火或阻燃性能的板、网等材料,形成封闭或半封闭的构架,并采取在桥架及其支吊架表面涂防火涂料等措施,整体耐火性能应符合相关规范或标准的要求。
2. For areas where the cable tray needs to be fire-resistant, you can add fire-resistant or flame-retardant boards, nets and other materials to the cable ladder and bridge to form a closed or semi-enclosed structure, and apply coating on the surface of the bridge and its supports and hangers. Fire-resistant coatings and other measures, the overall fire resistance performance should meet the requirements of relevant regulations or standards.

3.在防火要求高的地方,选取铝电缆桥架不适合。
3. In places with high fire protection requirements, it is not suitable to choose aluminum cable trays.
4.电缆梯架和桥架的宽度和高度的选挑应满足填充率的要求。电缆梯架和桥架填充率在1状况,以下,电力电缆可选用百分之40至百分之50的电缆,控制电缆可选用百分之50至百分之70,的电缆,并预留百分之10至百分之25项目的开发余量。
4. The selection of the width and height of the cable ladder and bridge should meet the requirements of the filling rate. If the filling rate of the cable ladder and bridge is below 1, 40-50% of the power cables can be used, and 50% to 70% of the control cables can be used, and 100% are reserved. 10 to 25% of the project's development margin.
5.在选挑,电缆桥架的荷载等级中,电缆桥架的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,当假如电缆桥架吊架的实际跨度不等于2m时,电缆桥架的均布荷载应满足要求。
5. In the selection and selection of the load level of the cable tray, the uniform load of the cable tray should not be greater than the rated uniform load of the selected cable tray load level. If the actual span of the cable tray hanger is not equal to 2m, the cable tray The uniform load should meet the requirements.
6.在满足相应荷载的情况下,各种构件、支吊架的规格和尺寸应与和托盘、梯架直段和弯曲系列相匹配。
6. Under the condition that the corresponding load is met, the specifications and dimensions of various components, supports and hangers should match the straight section and curved series of pallets and ladder frames.
7.当选挑电缆槽弯曲或上下引导设备时,不应小于电缆槽中电缆的较小允许弯曲半径。
7. When choosing to bend the cable trough or guide the equipment up and down, it should not be smaller than the smaller allowable bending radius of the cable in the cable trough.
8.对于跨度大于6m的钢索桥和跨度大于2m或承载要求大于荷载等级D的铝索桥,应根据工程情况计算或测试实行强度、刚度和稳定性。
8. For steel cable bridges with a span greater than 6m and aluminum cable bridges with a span greater than 2m or load requirements greater than load class D, the strength, rigidity and stability shall be calculated or tested according to the engineering conditions.
9.当几组山东电缆桥架槽与高度平行敷设时,相邻电缆槽之间的差距应由商酌维护和检修。
9. When several sets of Shandong cable tray troughs are laid in parallel with the height, the gap between adjacent cable troughs should be maintained and repaired by consultation.
