Cable tray can be divided into trough type, tray type and ladder type, grid format, etc. it is composed of bracket, bracket and device accessories. What are the types of cable tray? What should we pay attention to? To clarify the classification of cable tray and device requirements.
1. Ladder type cable tray
The ladder type cable tray is improved and planned according to the relevant data at home and abroad. This kind of cable tray has the advantages of low cost, light weight, special shape, good heat dissipation and good ventilation. It is usually used in larger diameter cables, and is more suitable for high or low pressure power cables.
2. Tray type cable tray
The advantages are light weight, heavy load, beautiful shape, simple structure, and easy installation. It is usually used in petroleum, chemical, light industry, telecommunications, etc. it is suitable for power cable installation and can also be used to control cables.
3. Trough cable tray
This is a completely enclosed cable tray, suitable for control cables with high flexibility system, such as computer cables, communication cables, etc. it can effectively shield the interference of control cables and heavy corrosion in the environment, with super good protection effect.
4. Long span cable tray
It has long service life, simple installation, low cost and easy cutting. The key point is that it does not need maintenance. It is very convenient to use. It is assembled by pultruded FRP profiles and can be used in power cables, control cables, lighting cables or other accessories.
1. When the cable tray meets the equipment that needs electricity, the distance between them should be more than 0.5m.
2. When the two groups of cables are parallel at the same height, the distance between them should be greater than 0.6m.
3. When laying the cables in the trunking, the cables in the trunking should be straight.
4. When setting in the ceiling, the open side of the slot cover should adhere to the vertical clearance of 80mm, and the utilization rate of the slot section should be less than 50%.
The above summary is the classification of cable tray and the requirements of the device, so we must pay attention to the device, so that we can complete the project with high energy rate and safety.
