Steel trough cable tray installation method

The installation of steel trough cable tray is a systematic project, involving many aspects of operation and precautions. The following is a detailed introduction to the installation methods of steel trough cable tray, including hoisting, grooving, connection, fixing, grounding, etc.

1. Hoisting: Hoisting is the first step in the installation of steel trough cable tray, mainly using a crane or a hanger to hoist the cable tray from the storage location to the installation location. During the hoisting process, the stability of the cable tray must be ensured to avoid large swings or violent collisions. At the same time, the hoisting method and the location of the hoisting point should be reasonably selected to prevent the cable tray from deformation or damage.

2. Groove drop: Groove drop is to put the hoisted cable tray into a pre-designed groove or groove. During the groove drop process, the cable tray must be placed stably to avoid tilting or dislocation. At the same time, the width and depth of the groove or groove should be reasonably adjusted according to the specifications and design requirements of the cable tray to ensure that the cable tray can be installed smoothly and maintain stability.

3. Connection: Connection refers to the process of connecting multiple cable trays into a whole. During the connection process, appropriate connection methods should be used, such as bolt connection, riveting connection, etc., to ensure that the connection is firm and reliable. At the same time, the flatness and straightness of the joints should be ensured to prevent stress concentration or irregular deformation.

4. Fixing: Fixing is the process of fixing the steel trough cable tray in a specified position. During the fixing process, appropriate fixing methods and fixings, such as brackets, clips, etc., should be used to ensure the stability and safety of the cable tray. At the same time, the fixing points should be set reasonably to avoid excessive or unstable fixing.

5. Grounding: Grounding is the process of connecting the steel trough cable tray to the earth, and it is an important measure to ensure the safety of electricity use. During the grounding process, reliable grounding methods and grounding materials, such as grounding wires, should be used to ensure the continuity and reliability of grounding. At the same time, attention should be paid to the size of the grounding resistance to meet the requirements of relevant specifications and standards.
