First, what is the bridge

Baidu's more official explanation: ‘cable tray is divided into grooved cable tray, tray cable tray and ladder type cable tray, grid bridge and other structures, by the bracket, bracket arm and installation accessories and other components. Can be set up independently, can also be laid in a variety of buildings (structures) and corridors on the support, reflecting the structure is simple, beautiful, flexible configuration and easy maintenance features, all parts need to be galvanised, installed outside the building in the open air bridge, if it is in the vicinity of the seashore or belongs to the corrosive zone, the material must be corrosion-resistant, moisture-resistant, good adhesion, impact strength of the physical characteristics of the high. ’

In fact, to put it simply, is a bridge is a cable laying equipment.

Second, the role of the bridge

Cable tray has three main roles: to protect cables, management cables, support cables.

The bridge is actually a very large number of types, there are fully enclosed slot, ladder, tray type, and a variety of materials of different bridges. In construction projects, the traditional way of wiring is to bury the wall or through the pipe. This way can also play a protective role for cables. But later when the cable needs to increase, the traditional buried wall or through the pipe maintenance is very troublesome, but the use of bridge wiring is very convenient, only need to open the cover can increase the cable.

The second point is that the bridge is not only a variety of materials, but also a variety of styles, more beautiful, beautiful, applicable to more scenes.

The third point is the function of the bridge, such as hot dip zinc bridge, the surface zinc layer ≥ 65μm, very suitable for outdoor wiring when used, can be beneficial to protect the cable by the nature of the rain and snow, small animals on the cable damage. Another example is the aluminium alloy bridge, it is very suitable for wiring in the machine room, conducive to anti-electromagnetic interference. There are 316 stainless steel is generally used for reservoir project wiring, relative humidity, temperature changeable environment, 316 stainless steel bridge is more stable.

Therefore, the use of bridge integrated wiring is better than the traditional buried wall or through the pipe!
