Mobile WebSitePeople often confuse the bridge with the trunking. For both of them, are you also in the clouds?
Cable trays are divided into: trough, tray and ladder, net format and other structures, consisting of brackets, support arms and mounting accessories. The trunking can be divided into: insulated wiring trough, split wiring trough, mini wiring trough, separate wiring trough, interior wiring trough, integrated insulated wiring trough, telephone wiring trough, Japanese Telephone wiring trough, open wiring trough, circular wiring duct, exhibition partition wiring trough, cover wiring trough, etc.
What is the bridge
The bridge is a support for supporting and laying cables. Bridges are widely used in engineering. As long as the cables are laid, bridges and cable trays are used as a supporting project for the wiring project. There is no specific specification guidance at present, and the specifications of a manufacturer lack generality.
Basic category of the bridge
1. Cascade cable tray
The CQ1-T stepped cable tray is improved according to relevant information at home and abroad. It has the advantages of light weight, low cost, unique shape, convenient installation, heat dissipation and good ventilation. He is suitable for the laying of large diameter cables, suitable for laying high and low voltage internal chain power cables.
2, tray cable tray
Tray cable trays are the most widely used in petroleum, chemical, light industry and telecommunications. The utility model has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. It is suitable for the installation of power cables and for the laying of control cables.
3, trough cable tray
The trough cable tray is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables and other highly sensitive system control cables. It shields the cable from interference and corrodes the cable in the environment. Protection has a good effect.
Trunking characteristics
1, suitable for large span installation
The busbar housing is made of roll forming, small in size and beautiful in appearance, which greatly improves the load capacity of the plant. It can load 60Kg in the center of the span 6m busbar and the deflection is less than 10mm.
2, the installation is very convenient
The use of automatic compensation coupling and single-bolt clamping terminal, the adjustable, so that the busway is very convenient and flexible during the installation process, greatly saving installation time.
3, extremely safe and reliable
With the separation air insulation type, the safety clearance and creepage distance between the phases are far greater than the standard requirements.
4, flexible wiring
The busway sockets are modular in design and a large number of sockets are reserved for the entire system. Ensure that the load can be connected to the busway unit in the shortest path. There is no need to change the busbar system for the addition, movement and workshop refurbishment of the shop floor equipment.
5, strong interchangeability
The busway is designed with seven current levels and uses only three levels of housing so that when the system changes capacity at adjacent current levels, there is no need to replace the case.
The total difference between the bridge and the trunk
1. The bridge frame is used for laying power cables and control cables, and the wire slots are for laying wires and communication cables;
2, the bridge is relatively large, the floor of the general building, the various power distribution rooms, etc. are used more. The trunking is relatively small
3. The bending radius of the bridge is relatively large, and most of the trunkings are bent at right angles;
4. The span of the bridge is relatively large, the slot is relatively small, and the fixing and installation methods are different;
5. In some places, the bridge is not covered, and the trunking is almost completely sealed with a cover. The trunking is used in various power distribution cabinets and instrument cabinets;
6. The cable trough is used for routing, and the bridge is used to take the cable.
