When wiring, using a metal structure called a cable tray can effectively protect the cables. Cable racks are used to lay a large number of cables in an orderly and efficient manner, especially over long and straight distances. It is also used to classify cables and connect them together to achieve the same purpose. Select and use appropriate materials and shapes according to the installation location and purpose. Cable racks are used in relatively large facilities such as stations, public facilities, factories, research laboratories, etc. By using cable racks, a large number of cables can be laid in an orderly and efficient manner. This not only ensures the safety of the facility but also improves operability. It also helps to reduce accidents and failures by laying cables with the same purpose such as power lines and signal lines together.
Cable racks can be installed indoors or outdoors, but it is best to install them after considering various factors such as avoiding damage to the cables themselves, ensuring work efficiency and safety, and considering the design. Cable racks are made of a variety of materials, including galvanized steel, aluminum, reinforced plastic, and synthetic resin. Any material can be used for indoor installation, but when installed outdoors or in places where gas may be generated, please select environmentally friendly materials such as plated steel or reinforced plastic respectively. The ladder type is suitable for vertical installation because it is easy to fix cables and has high visibility. The tray type is suitable for horizontal installation because the cable itself can be fixed and kept stable. In addition, since the cable can be hidden, the design can be ensured, and the shielding effect can be expected to a certain extent in various exposure environments.
. On the contrary, due to the lack of visibility of the cable, the efficiency of maintenance and other work may decrease. To install the cable tray, push the plug into the ceiling and hang the bolts. Then install the cable rack, center rack, separator, and end cap. Also consider the distance to support the cable rack, the bending radius of the cable, the wiring method, and the fixing method. If the cable rack is made of steel, it should be supported at intervals of 2m or less, and if it is other materials, it should be supported at intervals of 1.5m or less. Where straight lines and other shapes are connected, support near the point and near the edge of the cable rack. When installing the cable rack vertically, support it at intervals of 3m or less. However, parts such as wiring rooms can be supported at 6m or less. Cables should be supported at intervals of 3m or less in horizontal positions and 1.5m or less in vertical positions. The exception is when the cable rack is tray-type or runs in a double-layer ceiling. When running cables vertically, avoid concentrating the weight on one lug. Also, the power
