◉ The installation of cable tray is usually carried out near the end of the ground work. At present the world’s popular cable tray a variety of types, each country and region of the cable tray implementation standards are not consistent, the installation method will also have some differences, but generally still follow some basic principles.
◉ First of all, from the function of the cable tray, the purpose of the existence of the cable tray is to lift the cable off the ground or laid in the air, in order to prevent the cable directly grounded and not eroded by foreign objects, to achieve the main purpose of protection. Secondly, part of the cable tray also has a shielding electrostatic interference and the role of regular wiring, not only can reduce the signal cable transmission process by electronic interference, but also the cable neatly arranged to achieve the effect of beautiful appearance. Then for the above respective characteristics, each country and region in accordance with their respective needs have developed a corresponding national standards or industry standards, so the cable tray in the installation process, involving the relevant components can be roughly divided into the following categories:
◉ 1.Cable tray support system components. Support system components mainly include profile structural members or brackets (brackets), fasteners (bolts, screws, spring nuts and anchor bolts, etc.), fixed parts (pressure plate, shims), lifting parts (screws, hangers) and so on. The specific assembly can be seen in the figure below:
◉ 2. Cable tray connection components. Generally speaking, the cable tray connecting components including connecting pieces and connectors (elbows, tees, crosses, etc.). These components or parts due to the different shape of the cable tray and different shapes. Its role is to connect the fixed cable tray in the gap between the cable tray.
◉ The selection of these connecting components and parts should be based on project requirements and cable tray standards to position, for example, most of the cable tray and cable tray connection is used to connect the piece connection, and then fasteners to lock fixed. This structure is simple and efficient, easy to install. It is the most popular installation method.
◉ The installation of the cable tray connector with the same cable tray installation, is also used to connect the piece of fixed installation. Specific installation into the following figure.
◉ Of course, there are very few cable tray is removed from the cable tray connecting piece of this part, in the two ends of the cable tray can be made to butt the structure, nested in each other and then fasteners to lock fixed. This structure needs to leave space for nesting depth during installation to facilitate nesting installation.
◉ 3.Cable tray sealing assembly. The sealing assembly contains the cable tray cover plate and the cover plate latch. The main function of the component is to protect the cable tray from dust, heavy objects, rain erosion or damage. To install, simply snap the cover over the cable tray and secure the cover with the latch.
◉ The main purpose of cable tray being designed and applied to the project is protection and aesthetics, so the installation process of cable tray is relatively uncomplicated. If the installation is too cumbersome, the original purpose of the cable tray design is lost.
