Cable trays make the laying of cable lines and the network wiring of high-rise buildings neat,beautiful,and standardized.They also achieve standardization,serialization,and universality in engineering design,providing a new way to beautify the environment and ensure safe production.Busbar duct accessories are an important part of cable trays.Cable trays have the advantages of compact and reasonable structure,strong load-bearing capacity,flexible configuration,easy installation,and complete specifications.They are widely used in intelligent weak current system engineering.

　　Cable trays make the laying of cable lines and the network wiring of high-rise buildings neat,beautiful,and standardized.They also achieve standardization,serialization,and universality in engineering design,providing a new way to beautify the environment and ensure safe production.Cable trays have the characteristics of wide application,high strength,light structure,low cost,simple construction,flexible wiring,safety standards,and beautiful appearance.Cable tray pipe joints bring convenience to technical manufacturing,cable expansion,maintenance and repair.A cable tray is composed of trays,ladders(straight sections,bends,accessories,and supports),etc.,used to support cables and has a continuous rigid structural system.

　　Trough type cable tray is a fully enclosed cable tray.It is suitable for laying computer cables,communication cables,weak current system cables,thermocouple cables,and control cables for other high-sensitivity systems.It has good effects on shielding interference of control cables and protecting cables in heavily corrosive environments.The ladder type cable tray has the characteristics of light weight,low cost of tray pipe joints,unique design,and good ventilation and heat dissipation performance.It is suitable for laying cables with larger diameters,especially for laying high and low voltage power cables.Tray type cable tray is an ideal laying device widely used in petroleum,chemical,power,television and telecommunications industries.It has the advantages of light weight,large load capacity,beautiful appearance,simple structure,easy installation,and good heat dissipation and breathability.It is suitable for both the installation of power cables and the laying of control cables.

　　The cable tray is introduced from the weak current shaft into the control room.In the control room,an elevated anti-static floor should be laid,and metal cable trays should be installed under the elevated anti-static floor to connect the horizontal cable tray,vertical cable tray,and wiring cabinet.Vertical cables run through the entire building through vertical cable trays,which provide a pathway for the vertical main line in the weak current shaft.The weak current system vertical cable tray is installed in the cable shaft of the wiring room on each floor.The cables of each system are led out through the cable tray on each floor and enter the horizontal main bridge frame on each floor.
