山东电缆桥架种类多样,每座桥架在使用中都可以发挥一定的优势,有利于桥架的整体使用效果和桥架的后期使用。那么山东电缆桥架中的梯式桥架应如何安装?
Shandong cable tray types are diverse, each bridge can play a certain advantage in use, is conducive to the overall use of the bridge effect and the later use of the bridge. Then how to install the ladder bridge in Shandong cable bridge?
电缆桥架和线槽的敷设方向应短而快,尽量沿墙、柱或梁敷设。根据电缆桥架及线槽的敷设趋势,预留墙洞、楼板洞及吊架安装所需预埋钢板的位置及荷载向土建及结构提出。并应与工艺、水暖、电力相协调。地下暗金属线槽的布线应与土建设计紧密配合,根据不同的结构类型和建筑布局合理确定线路和设备选型。
The laying direction of cable tray and trough should be short and fast, as far as possible along the wall, column or beam laying. According to the laying trend of cable tray and trough, the position and load of the embedded steel plate required for the installation of reserved wall hole, floor hole and hanger are proposed to the civil engineering and structure specialty. And should be in harmony with craft specialty, plumbing specialty, electric power specialty. The wiring of underground dark metal wire trough should be closely coordinated with the professional design of civil engineering, and the selection of lines and equipment should be reasonably determined according to different structural types and building layout.
不同电压和用途的电缆不应敷设在同一层电缆桥架内:1kV以上、1kV以下的电缆;用于向同一路径上的主负载供电的双回路电缆;应急照明及其他照明电缆;电力、控制和电信电缆。如果不同等级的电缆敷设在同一个电缆桥架上,则应在中间增加一个隔板进行隔离。工程条件下安装或维修不考虑附加集中荷载时,电缆梯架和桥架的工作均布荷载按电缆自重均匀分布计算。
Cables of different voltages and uses should not be laid in the same layer cable tray: cables above 1kV and below 1kV; A double-loop cable for supplying power to the main load on the same path; Emergency lighting and other lighting cables; Power, control and telecommunication cables. If different grades of cables are laid on the same cable bridge, a partition should be added in the middle for isolation. When additional concentrated load is not considered in installation or maintenance under engineering conditions, uniform working load of cable ladder and bridge is calculated according to uniform distribution of cable dead weight.
山东电缆桥架不应与下列管道平行敷设。如果不可避免,电缆桥架的位置应符合下列要求,或采取相应的保护措施:
Shandong cable tray should not be laid in parallel with the following pipelines. If unavoidable, the position of the cable tray should meet the following requirements, or take corresponding protection measures:
电缆桥架应在腐蚀性液体管道上方。电缆桥架应位于热管下方。当易燃易爆气体比空气重时,电缆桥架应在管道上方。当易燃易爆气体比空气轻时,电缆桥架应在管道下方。电缆桥架与管道之间的较小距离见相关标准。综合配线电缆与附近可能产生高电平电磁干扰的电气设备(如电机和电力变压器)之间应保持必要的距离。综合配线电缆与电力电缆的间距应符合相关规定。敷设在墙上的综合配线电缆、光缆和管道与其他管道之间的距离应符合有关规定。
Cable tray should be above corrosive liquid pipeline. The cable tray should be located below the heat pipe. When flammable and explosive gas is heavier than air, the cable bridge should be above the pipe. When flammable and explosive gas is lighter than air, the cable tray should be below the pipe. The smaller distance between cable tray and pipe is shown in relevant standards. A necessary distance should be kept between integrated wiring cables and nearby electrical equipment (such as motors and power transformers) that may generate high level electromagnetic interference. The distance between integrated wiring cables and power cables should comply with relevant regulations. The distance between the integrated wiring cables, optical cables and pipes laid on the wall and other pipes shall conform to the relevant regulations.
The above is some key points of the installation of ladder type bridge in Shandong cable bridge. Whether the laying of the bridge can meet certain specifications should be clearly stipulated in the installation process, so as to facilitate the use.
