The bridge is composed of a tray and a ladder frame line, bent through, attachment and support and hanger which used to support the general cable has the continuous rigid structure system. Is applied in the horizontal and vertical wiring system installation channel. The cable tray is to wire, cable, cable laying cable to achieve standardization and universalization of the laying device. Note here a concept of the tray, a lot of people put the tray and tray together, that function is roughly the same, in fact. The bridge with the slot there is a big difference, mainly has: the bridge is mainly used for laying power cables and control cables, wire slot for laying wire and cable tray; relatively large (200 x 100 to 600 x 200 ), trough bridge is relatively small; the turning radius is relatively large, trough of bending at a right angle; the bridge span is relatively large, relatively small, fixed line groove; different installation modes; in some places, the bridge did not cover the slot is usually full of slot with lid closed to walk the line, the bridge is used to take the cable. Therefore, we should pay attention to in the selection of the bridge, in order to avoid the wrong but did not achieve their intended purpose.

 

 

The traditional bridge are: trough cable tray, tray type cable tray, cable trays, big span cable tray, combination type cable tray, flame retardant glass steel cable tray, corrosion Aluminum Alloy cable tray etc.. These are also present in Chinese applications more bridge, for closing bridge. What kind of environment with what type of bridge, which is a very important issue. Trough cable tray, is a fully enclosed type cable bridge, cable protection it is most suitable for laying computer cable, communication cable, thermocouple cable and other highly sensitive system of control cable shielding interference and heavy corrosion environment have good effect. Tray type cable tray, which has the advantages of light weight, heavy load, beautiful appearance, simple structure, convenient installation, it is suitable for the installation of power cable is also suitable for the control of cable laying. Ladder type cable tray, suitable for direct light cables, especially suitable for high and low power cables....... The bridge just in energy saving and optimization of each one has its own merits, cable performance, less open structure bridge.

 

 

The installation of several main bridge along the roof installed along the wall, the horizontal and vertical installation, installation and installation along the shaft along the ground, along the cable trench and pipeline bracket installation etc.. To install the support (hanging) frame can be used to choose the finished product or homemade. The fixed mode of the support (hanging) frame is mainly welded on the pre embedded iron parts, and the expansion bolt is fixed and the like.

Where there is a cable tray. The scope of application of the bridge is quite extensive, all walks of life in mo

 

st applications in the data center, office, Internet service providers, hospitals, schools, airports and factories / University, especially the data center and IT room market is a future application of very large bridge.
