The cable tray is a support for supporting and placing cables. Shandong cable tray is widely used in engineering. As long as cables are laid, cable tray shall be used; Cable tray is divided into trough type cable tray, tray type cable tray, ladder type cable tray, grid type cable tray and other structures; It is composed of support, corbel, installation accessories, etc.
As a supporting project of wiring engineering, there is no special specification and guidance for cable tray at present, and the specification program of each manufacturer lacks universality. Therefore, the design and selection process should reasonably select the appropriate cable tray according to the type and quantity of cables in each weak current system.
It can be erected independently or laid on various buildings (structures) and pipe rack supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. The cable tray installed outside the building in the open air must have the physical characteristics of anti-corrosion, moisture resistance, good adhesion and high impact strength if it is near the sea or belongs to the corrosion area.
Cable tray is the full name of a rigid structural system with closely connected supporting cables, which is composed of straight sections, bends, components of tray or ladder, corbel (arm support), hanger, etc.
It is a technical reference for design selection and transaction guarantee; Cable raw materials, cable accessories, cable equipment, cable bridge, cable reel, construction tools, cable connectors, etc.
Cable tray is a derivative product for cable protection. It is the protective shell of the cable to prevent the cable from being damaged by external factors. It is mainly composed of supports, corbels and installation accessories. The main types of bridges can be divided into ladder type bridges, non hole tray type bridges (trough type bridges), perforated tray type bridges (tray type cable bridges), long-span cable bridges, etc.
What are the supporting items of the cabling bridge project? The above questions are explained from several aspects. In addition, if you want to use the cable tray for a longer time and more smoothly, you need to do a good job of inspection and maintenance.
