托盘式电缆桥架是石油、化工、电力、轻工、电视、电讯等方面应用广泛的一种。它具有重量轻,载荷大,造型美观、结构简单,安装方便等优点,它既适用于动力电缆的安装,也适用于控制电缆的敷设。
Tray type cable tray is the most widely used one in petroleum, chemical industry, electric power, light industry, television, telecommunications, etc. It has the advantages of light weight, large load, beautiful appearance, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables.
济南桥架厂家提醒,其表面处理可根据用户需要分为镀锌、静电喷塑和热镀锌三种,在重腐蚀环境中可作特殊防腐处理。
Jinan bridge manufacturer reminds that its surface treatment can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot galvanizing. In heavily corrosive environments, special anti-corrosion treatment can be applied.
施工安装要点:
Key points of construction and installation:
1)电缆桥架及线槽敷设走向应短捷,并应尽量沿墙、沿柱或沿梁敷设。
1) The laying direction of cable tray and trunking shall be short, and shall be laid along the wall, column or beam as far as possible.
2)根据电缆桥架及线槽敷设走向,向土建、结构提出预留墙洞、楼板洞及吊架安装时,所需预埋钢板位置及荷载。并且应与工艺、水暖及动力相协调。
2) According to the laying direction of cable tray and trunking, the position and load of the embedded steel plate required for the installation of reserved wall holes, floor holes and hangers are proposed to the civil engineering and structural disciplines. And it should be coordinated with the craft profession, plumbing profession, and power profession.
3)地面内暗装金属线槽布线,在设计时应与土建密切配合,以便根据不同的结构型式和建筑布局,合理确定线路路径和设备选型。
3) Concealed metal trunking wiring on the ground should be designed in close coordination with the civil engineering profession, in order to reasonably determine the route and equipment selection based on different structural types and building layouts.
4)不同电压、不同用途的电缆不宜敷设在同一层电缆桥架内:
4) Cables with different voltages and different purposes should not be laid in the same cable tray:
1kV以上和1kV及以下的电缆;
Cables above 1kV and below 1kV;
同一路径向一级负荷供电的双回路电缆;
Double circuit cables supplying power to primary loads along the same path;
济南桥架
应急照明和其他照明的电缆;
Emergency lighting and other lighting cables;
电力、控制和电信电缆。若不同等级的电缆敷设在同一电缆桥架时,中间应增加隔板隔离。
Power, control, and telecommunications cables. If cables of different grades are laid on the same cable tray, partition separation shall be added in the middle.
5)在工程条件下安装或检修不需考虑附加集中荷载时,电缆梯架、托盘的工作均布荷载按电缆自重均匀分布计算。
5) When installation or maintenance under engineering conditions do not require the consideration of additional concentrated loads, the working uniform load of cable ladders and trays is calculated based on the uniform distribution of the cable's own weight.
6)电缆桥架不宜与下列管道平行敷设,当无法避免时,电缆桥架的位置应符合下列规定,或采取相应防护措施。
6) The cable tray should not be laid in parallel with the following pipes. If it is unavoidable, the position of cable tray should comply with the following provisions, or take corresponding protective measures.
电缆桥架应在具有腐蚀性液体管道上方。
The cable tray shall be above the pipeline with corrosive liquid.
电缆桥架应在热力管道下方。
The cable tray shall be under the heating pipe.
易燃易爆气体比空气重时,电缆桥架应在管道上方。
When flammable and explosive gas is heavier than air, cable tray shall be above the pipeline.
易燃易爆气体比空气轻时,电缆桥架应在管道下方。
When flammable and explosive gas is lighter than air, cable tray shall be under the pipeline.
7)电缆桥架与管道之间小距离见相关标准。
7) See relevant standards for the small distance between cable tray and pipeline.
8)综合布线电缆与附近可能产生高电平电磁干扰的电动机、电力变压器等电气设备之间应保持必要的间距。
8) Necessary spacing should be maintained between the comprehensive wiring cable and nearby electrical equipment such as motors, power transformers, which may generate high-level electromagnetic interference.
9)墙上敷设的综合布线电缆、光缆及管线与其它管线的间距应符合GB/T50311-2000规范11.0.2条的规定。
9) The spacing between the integrated wiring cables, optical cables, and pipelines laid on the wall and other pipelines should comply with the provisions of Article 11.0.2 of GB/T50311-2000.
10)电缆桥架水平敷设时,宜按荷载曲线选取跨距进行支撑,跨距一般为1.5~3.0m。垂直敷设时,其固定间距不宜大于2m。
10) When cable tray is laid horizontally, the span should be selected for support according to the load curve, and the span is generally 1.5~3.0m. When laying vertically, the fixed spacing should not exceed 2m.
此外您要知道,托盘式电缆桥架可备护罩,需要配护罩时可在订货时注明,其所有配件与梯级式,槽式桥架通用。还有什么疑惑或者需求,就来我们网站咨询吧!
In addition, you should know that the tray type cable tray can be equipped with a shield. If a shield is required, it can be noted when ordering. All its accessories are common to the ladder type and trough type cable tray. If you have any doubts or needs, please come to our website Consult!
