How to install Huijue electrical cable trays

Installing Huijue electrical cable trays involves careful planning, proper support placement, and secure mounting to ensure safe and efficient cable management. Step 1: Plan the RouteBefore installation, review your approved shop drawings to determine the tray route, dimensions, installation height, and number of layers. Ensure the path avoids conflicts with other services like HVAC ducts, plumbing, or fire protection systems.

Maintain proper vertical separation if multiple layers are used, typically at least 30 cm between electrical and communication trays to prevent interference. Step 2: Select the Right Tray Type and SizeChoose the appropriate Huijue tray type based on your application: ladder trays for airflow and heavy cables, perforated trays for lighter loads, or solid-bottom trays for sensitive cables. Calculate tray width and depth according to cable count, type, and spacing guidelines to prevent overheating or overcrowding.

Step 3: Prepare the Installation AreaClear the pathway of obstructions and mark the tray route using a chalk line or laser level. Identify locations for bends, tees, or risers. Mark support points at intervals recommended by the manufacturer, typically every 1.

5 to 3 meters depending on tray type and load. Step 4: Install Supports and Mounting HardwareUse wall arms, ceiling struts, or center-hung supports to secure the trays. Ensure supports are level and capable of handling the tray load.

Maximum load per hanger is generally around 318–340 kg, with support spacing up to 3. 6 meters for center-hung systems. Step 5: Assemble and Secure the TraysConnect tray sections using couplers or splice plates.

Align trays straight and level, and secure them to the supports. Handle trays carefully to avoid coating damage. For bends or elevation changes, use the appropriate fittings and maintain smooth cable paths.

Step 6: Install Cables and GroundingLay cables neatly within the tray, following fill ratio guidelines (usually max 50%). Use cable ties or clamps to secure cables without over-tightening. Ensure proper grounding of the tray system according to local electrical codes.

Step 7: Final Checks and MaintenanceInspect the installation for alignment, secure connections, and clearance from other services. Verify that all supports and trays are stable and that cables are properly organized. Regular maintenance includes checking for sagging, loose connections, or corrosion to ensure long-term safety and performance.

By following these steps, Huijue electrical cable trays can be installed safely and efficiently, providing a durable and organized solution for electrical and communication cabling.
