How to set up Huijue cable trays

Huijue cable trays can be connected using splice plates, bolted connections, or quick-connect systems, ensuring proper alignment, grounding, and secure fastening for safety and stability.Step 1: Plan and PrepareBefore connecting trays, plan the route according to your site layout, considering clearance, load capacity, and cable separation requirements. Select the appropriate tray type (ladder, perforated, or solid-bottom) based on airflow, cable type, and load . Ensure you have the necessary tools such as a socket wrench, torque wrench, and insulated screwdriver, and materials like splice plates, bolts, and grounding cables .Step 2: Install SupportsSecure cable tray supports to walls, ceilings, or cabinet tops using the recommended screws (e.g., M6x16). Ensure the grounding side faces outward for easy connection of ground cables . Supports should be spaced properly, typically 1.5–3 meters apart, depending on tray type and load .Step 3: Connect Tray SectionsThere are several methods to join Huijue cable trays:Splice Plates/Bolted Connections: Use flat metal plates with pre-drilled holes to join two tray sections in a straight line. Bolt them securely using spanners or torque wrenches. This method is strong, reliable, and allows future disassembly .Quick-Connect Systems: Snap, slide, or twist trays together with minimal tools. This method is faster and reduces labor time by 30–50%, but may require compatible Huijue components .Angle or T-Junction Plates: Use L, T, or cross-shaped plates to connect trays at corners or splits, ensuring proper alignment for cable routing . Ensure that connectors are positioned between support points, not at the center of spans, to prevent sagging .Step 4: GroundingConnect a ground cable between the tray and its supports at each connection point. Ground trays at least every 15 meters and at both ends to maintain electrical continuity and safety . Use bonding jumpers at expansion joints or long outdoor runs.Step 5: Final ChecksAlign trays straight and level.Verify all bolts and connectors are tight.Ensure cables can be laid without kinks or obstruction.Confirm grounding continuity across the system . Following these steps ensures a stable, safe, and durable Huijue cable tray installation, allowing for easy maintenance and compliance with electrical standards.
