Cable tray can be divided into trough type, tray type and ladder type, grid office, etc. it is composed of support, bracket and device accessories. What are the types of cable tray? What should the device pay attention to? Next, we will clarify the classification and device requirements of cable tray.
1. Ladder type cable tray
The stepped cable tray is improved and planned according to the relevant materials at home and abroad. This cable tray has low cost, light weight, special shape, good heat dissipation and good air permeability. It is generally used for cables with large diameter, which is more suitable for high or low pressure power cables.
2. Tray type cable tray
The utility model has the advantages that the weight is very light, the negative weight is very large, the shape is beautiful, the structure is very simple, and the device is not difficult. It is generally used in petroleum, chemical industry, light industry, telecommunications, etc. the device suitable for power cables can also be used to control cables.
3. Trough type cable tray
This is a completely closed cable bridge, which is suitable for control cables with high sensitive system, such as computer cables, communication cables, etc. it can effectively shield the interference of control cables and heavy corrosion in the environment.
4. Long span cable tray
It has long service life, simple device, low cost and simple cutting. The key point is that it does not need maintenance and is particularly convenient to use. It is assembled from pultruded FRP profiles and can be used in power cables, control cables, lighting cables or other accessories.
5. Combined cable tray
According to the device on the site, it can be widened, led up and down at random, and the available pipe can be led out without drilling or welding. It belongs to a new type of bridge. It is a second-generation new product in the cable bridge. It is applied to various projects and units to facilitate the planning in the project and the transportation during production. It is a very excellent product.
1. The distance between the cable tray and the equipment to be powered shall be greater than 0.5m.
2. When two groups of cables are parallel at the same height, the distance shall be greater than 0.6m.
3. When laying the cables in the trunking, the cables in the trunking shall be smooth and straight.
4. When it is set inside the ceiling, the open side of the slot cover shall maintain a vertical clearance of 80mm, and the utilization rate of the trunking section shall be less than 50%.
以上概括是电缆桥架的分类跟装置要求，装置时千万要注意，这样才能够高 效率又安 全的完结工程。
The above summary is the classification of cable tray and device requirements. Pay attention to the installation, so that the project can be completed efficiently and safely.
