1. Cable Tray use high-quality steel plates processed into fully enclosed high-strength rectangular steel pipes, which are galvanized on the surface to greatly improve their corrosion resistance. The inside and outside of Cable Tray should be smooth and flat, without any sharp edges, and there should be no deformation such as twisting or curling.

2. Distribution box and socket box: used for turning and connecting wires in the wiring plane. Crossing is a cross path for laying lines, which can be transformed into different pipe shapes and adjusted in height within a certain range.

The junction box of Workshop cable tray is equipped with isolation plates inside to ensure isolation and shielding between strong and weak electricity. When the strong and weak electrical connections in the wiring plane are very complex, the cable tray adopts a deepened junction box in the horizontal position, and the horizontal cable trays are crossed, which greatly facilitates the routing of various lines.

3. Dedicated outlet: Used for wire extraction, it can be used as a power supply, telephone, video socket, or computer terminal outlet as needed. Set the first outlet 230mm away from the junction box, with a standard spacing of 600mm between outlets.

4. Connection support accessories: connectors are used for direct connection; Circular pipe joints are used for connecting circular pipes in junction boxes; Variable diameter joints are used for connecting cable trays and circular pipes; The terminal is used for the bridge terminal head; The bracket and adjustment bolt are used for Aluminum alloy cable tray and height adjustment. The length of the adjustment bolt depends on the construction conditions, and the height adjustment is generally 30-50mm. The S-shaped deepening special joint is used for longitudinal and transverse intersections or beam crossings; Flat bends are used at the corners of bridge frames; Vertical bends are used for the upper and lower connection ports of cable trays; Other specialized adhesives for cable trays are used at the connections between cable trays and junction boxes to prevent mortar from entering.
