Detailed introduction


大跨距槽式桥架.jpg

Application range of cable tray : suitable for high-strength cable trays in the world, the following power cables with a voltage of 10 kV, control cables, lighting wiring and other indoor, outdoor or overhead cables, tunnels and cable laying.




Structural characteristics and installation: high-strength cable trays have a complete range, wide application range, high strength, easy construction, flexible distribution, installation standards, appearance and appearance of your office transformation, cable TV, convenient maintenance, and high-strength cables brought by maintenance The expansion characteristics during the installation of the bridge can be adapted to local conditions and may vary with the laying of the pipes; .floors, beams under the ceiling; indoor office walls, column walls, tunnels, cable trench side walls, and also open air columns Pier installation work, large-story bridge lifting or vertical installation, beams can be symmetrical columns laying on both sides of high-strength cable trays can be horizontally and vertically laid; possible corners, T-shaped, cross-shaped branches; adjustable width, increase, adjust.



Installation of cable tray:




1. The arrangement of the cable bridge should be the weakest current level control cable, followed by the general control cables, low voltage power cables, and high voltage power cables in order. This arrangement is good for shielding interference, cooling of power cables, and convenient construction.




2. The distance between the cable bridge layer and the layer: control cable> 200mm power line> 300mm mechanized cable> 400mm laying. table-



1 step, tray cable tray (T, p) stair, tray cable tray, can be widely used in petroleum, chemical, power, light industry, television, telecommunications, coal, laying cables and other aspects. They have a beautiful appearance, simple structure, easy installation (thermal conductivity) and so on. Ladder type cable bridge is suitable for the requirements of power cables, and to control the laying of cables, it can also be used in conjunction with the isolation cable bridge to lay power cables and control cables. Steps, tray cable trays to electrostatic spraying surface treatment, galvanized, hot-dip galvanized zinc, and then sprayed four kinds, can be used in different environments, respectively, should be a special anti-corrosion treatment in heavy corrosion environments.




2-slot cable tray




Trough cable tray is a kind of fully enclosed cable tray, which is ideal for laying sensitive cables such as computer cables, communication cables, thermocouple cables and control cables. It controls the interference of shielded cables and the protection of cables in highly corrosive environments. The trough cable tray is treated with electrostatic spraying surface, galvanized, hot-dip galvanized zinc, and then sprayed four types, which can be used for different environments. The severe corrosion environment should be a special anti-corrosion treatment.




3Assembly cable tray


Assembled cable tray bridge is the latest update product of a series of cable trays. It is suitable for laying various projects, various units, and various cables. It has the characteristics of simple structure, flexible configuration, convenient installation and novel form. As long as the three basic types can be combined into the cable frame you need, the assembly width is 100,150,200 cable bridge, it does not need to produce elbows, tees and other accessories. You can change a wide range of branches without any conversion on the spot. Take it down. It can be used for pipe lead without drilling or welding in any part. It can facilitate engineering design, production, convenient transportation, and more convenient installation and construction. It is currently the best cable bridge in the product. Assemble the cable tray cover. The surface treatment is electrostatic spraying, galvanizing, hot-dip galvanizing zinc, and then spraying four kinds, which can be used for different environments. The severe corrosion environment should be a special anti-corrosion treatment.




4 long span cable tray

Large-span cable trays are the more common support for cable tray spans. Because of their compact structure design, they have a larger carrying capacity than other cable trays. Therefore, it is not only suitable for indoor and outdoor overhead cable laying oil refining, chemical, textile, machinery, metallurgy, electricity, television, broadcasting and other industrial and mining enterprises, but also as underground works, such as: subway, cable trench wind defense engineering and cable tunnel support . Long-span cable trays include large-span ladders, trays, troughs, and heavy-duty ladders, corresponding models and accessories, with lids and lids. When ordering when needed, the height is 60 mm, 100 mm and 150 mm. Meter length, 6 meters, 7 meters 3, the user can arbitrarily determine the order and display type, height, width, length in the contract according to the needs of the project. Long-span cable bridge surface treatment department plastic coating, galvanizing, spray painting and other treatments, in heavy corrosive environments, spray galvanized after spraying.
