Huijue Cable Tray Cabling Techniques

To set up cable tray connectors in Huijue, align the tray sections, secure them with the manufacturer's connectors, and ensure proper support and grounding according to standards.

Step 1: Plan the Layout

Before installation, carefully plan the cable tray route, including straight runs, elbows, tees, and crosses. Consider cable entry and exit points, support bracket locations, and spacing between parallel trays for maintenance and inspection . Ensure the layout complies with local electrical codes and manufacturer specifications .

Step 2: Prepare Components

Gather all necessary components:

• Cable tray sections (straight, elbows, tees, crosses)
• Connectors compatible with Huijue trays
• Support brackets, bolts, nuts, and washers
• Hand tools: drill, screwdriver, level Inspect all trays and connectors for damage before installation .

Step 3: Install Support Brackets

Mark the positions for support brackets along walls, ceilings, or floors. Brackets should be spaced according to the tray type and load, typically placing connectors between the support point and the quarter-point of the span, avoiding the center of the span . Secure brackets using appropriate fasteners and ensure they are level .

Step 4: Connect Tray Sections

1. Align the ends of the tray sections to be joined.
2. Use the designated Huijue connectors (straight, elbow, tee, or cross) to join sections.
3. Insert bolts, nuts, and washers as per the manufacturer's instructions.
4. Ensure the connection is tight and the tray is level, with no sagging .

Step 5: Install Elbows, Tees, and Crosses

For directional changes:

• Elbows (ELB90): Connect horizontal or vertical bends.
• Tees (TEE): Join three tray sections at intersections.
• Crosses (CRS): Join four tray sections at cross points . Follow the same alignment and fastening procedure as straight sections.

Step 6: Grounding and Bonding

Install bonding jumpers at expansion joints and long runs to maintain electrical continuity. Ground the cable tray system at least every 15 m (50 ft) and at both ends. Bond conduit drop-outs to the tray using a grounding bushing or compression lug .

Step 7: Final Inspection

Check all connections for tightness, alignment, and stability. Verify that supports, connectors, and grounding comply with standards and manufacturer instructions . Ensure cables are properly routed and secured within the trays. By following these steps, Huijue cable tray connectors can be installed safely, efficiently, and in compliance with electrical standards.
