At present, the variety of cable tray is still comprehensive, and its application is also very extensive. Therefore, it will be required that such cable tray should be light in structure, low in cost, convenient and simple in construction, and of course beautiful. It is important to pay attention to whether the installation standard of this cable tray is up to standard. Next, Shandong cable tray manufacturer will introduce some knowledge points related to cable tray.
1. Structure mode
At present, this type of bridge is divided into trough type bridge, tray type bridge, ladder type bridge and grid type bridge. It is usually composed of bracket, bracket and installation accessories. These knowledge points are necessary for cable bridge wiring engineering
2. Process variety
At present, this type of bridge has adopted such processes as cold galvanizing, hot galvanizing, electrostatic spraying, fireproof coating and baking paint.
At present, this type of bridge is characterized by a rigid structure with tightly connected supporting cables, which is composed of slot, tray or stepped straight section, elbow, tee, cross component, arm bracket, hanger, etc. At present, this method has been widely recognized in the market, and the product selection of excellent cold-rolled steel plate is relatively mature.
These knowledge points are necessary for cable tray wiring engineering. At present, there are several conventional cable tray modes, such as ladder type, tray type, trough type, large span type and combined type.
At present, such products are mainly used in petrochemical industry, metallurgy, electric power, school communication, and high-rise buildings, so the corrosion resistance, versatility, and aesthetic appearance of such bridges are required. It should be noted that in the design of the arrangement of the wiring mode and route selection, the requirements of the specification should be taken into account, as well as the safety, scalability, economy and maintainability of the wiring.
The cable tray is used to support and hold cables, and the cable tray is also the equipment of wiring engineering. At present, there is still no clear specification guidance, and many manufacturers' specifications and forms are still lack of universal nature. Therefore, in the process of design and selection, a reasonable bridge mode should be selected according to the cable type and quantity of each electrical system.
