Cable bridge, as an important part of power system, as we all know electricity is the guarantee of our daily life, so is supposed to cable tray for us to occupy the important role that bridge in different environments, the use of the bridge type is not the same.
Shandong cable tray
Tray type cable tray is petroleum, chemical industry, light industry, TV, telecom etc. One of the most widely used. It has a light weight and load big, beautiful modelling, the advantages of simple structure, convenient installation. The same tray type cable tray installation of environmental requirements:
1) tray type cable tray is suitable for the installation of power cable, is used to control the laying of the cable. Tray type cable tray its surface treatment is divided into plating and painting two kinds, in heavy corrosion environment can special anticorrosive processing. Tray type cable tray with cover, all of its parts and tray type, slot type bridge.
2) steam-water tray type cable tray, trough and its use in corrosive environment, the corrosion resistance of the rigid materials should be adopted, or corrosion resistance, anti-corrosion treatment shall meet the requirements of engineering environment and durability.
3) cable bridge, there is a requirement for fire prevention in the segment can be added within the cable ladder, tray with fire or fire resistant performance of plate, the material such as network forms a closed or semi-closed structure, and take in the steam-water bridge and its surface besmear to brush fire retardant coating, its overall refractory performance should meet the requirements of relevant national norms or standards.
4) the demand is higher in the engineering in place, unfavorable use aluminum alloy cable bridge in shandong.
