1. Ladder type cable tray
The ladder type cable tray is improved and planned according to the relevant materials 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 generally used in cables with large diameter, and is more suitable for high or low pressure power cables.
2. Tray type cable tray
It has the advantages of light weight, large negative weight, beautiful appearance, simple structure, and easy installation. It is generally used in petroleum, chemical, light industry, telecommunications, etc. it can also be used to control power cables.
3. Trough cable tray
This is a completely enclosed cable bridge, which is most suitable for control cables with high sensitivity system, such as computer cables, communication cables, etc. it can effectively shield the interference of control cables and heavy corrosion in the environment, and has super good protection.
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.
5. Combined cable tray
According to the on-site device, it can turn at will, widen, separate and lead up and down, and lead out the available pipes at random positions without drilling or welding. It belongs to a new type of bridge and is the second generation of new product in the cable bridge. It is used in various projects and units to facilitate the planning of projects and the transportation of production. It is a very excellent product.
1. The distance between the cable tray and the equipment to use electricity should be more than 0.5m.
2. When two groups of cables are parallel at the same height, the distance 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 maintain a vertical clearance of 80mm, and the utilization rate of the slot section should be less than 50%.
The above summary is the classification and installation requirements of cable tray. Attention must be paid to the installation, so as to complete the project efficiently and safely.
