Youdaoplaceholder0 cable tray solutions are divided into trough type, tray type, ladder type, mesh type and other structures, and consist of brackets, arms and installation accessories, etc. The cable tray inside the building can be independently erected or laid on various building and pipe gallery supports. It should feature a simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. The cable tray installed outdoors in the building.
1. Determine the environmental conditions
There are generally three types of environmental conditions. One is the corrosive environment, such as chlor-alkali plants, etc. The second is the general environment, that is, the normal environment, such as atmospheric corrosion. The third type is special environments, such as exhibition halls and display rooms. Where are trough cable tray solutions used and where should appropriate trough cable tray solutions be reasonably selected
2. Determine the direction
Based on the general layout plan and in combination with the specific conditions of process pipelines, water pipelines, steam pipelines, etc., determine the path of trough cable tray solutions. Indoors, it can be erected along walls, beams, columns and floor slabs. When setting up outdoors, it is advisable to do so along one side of the process pipe rack as much as possible. If there is no pipe rack to rely on, only self-supporting pillars can be erected.
3. Load calculation
Calculate the weight of the cable per unit length on the longitudinal section (i.e., the heading section) of the main trunk line of trough cable tray solutions.
4. Determine the width of the bridge frame
Determine the model and specification of trough cable tray solutions, the length and spacing of the tray arms based on the calculated load. The width and number of layers of trough cable tray solutions are determined according to the number of cables.
5. Determine the installation method
Determine the fixing method of trough cable tray solutions based on the surrounding conditions, whether it is suspended, upright, side-wall or hybrid.
6. Select connecting parts and fasteners
The connecting parts and fasteners are a set. Once the connecting parts are determined, the fasteners are also determined accordingly.
7. Select the cover plate.
8. Draw the floor plan and section view of trough cable tray solutions, draw the space diagram, and list the material list.
