Installation Procedure

The installation of grid cable trays follows a structured method to ensure safety, accessibility, and durability: Material Inspection and Preparation: All cable trays, ladders, and fittings should be inspected for damage and verified against approved material submittals. Unsuitable materials must be removed immediately. Storage: Store trays horizontally on a flat surface with timber supports at 1-meter intervals, protecting them from moisture and direct sunlight.

Review Shop Drawings: Examine approved shop drawings to determine tray layout, lengths, and routing. Ensure horizontal and vertical runs are clearly marked. Site Preparation: Clean the installation area and ensure civil works are complete.

Mark tray routes, maintaining clearance for cable pulling and future maintenance. Supports and Hanging Systems: Install supports and hangers according to design specifications, ensuring proper alignment and load distribution. Installation: Assemble and secure trays and ladders, connecting sections with appropriate fittings.

Maintain proper grounding and bonding as per electrical codes. Verification and Testing: After installation, inspect all connections, supports, and alignment. Conduct certified testing for continuity, grounding, and load capacity.

Best Practices

Maintain clearance from other services to avoid interference. Use corrosion-resistant materials like galvanized steel for durability in humid or industrial environments. Ensure trained personnel handle installation to comply with occupational health and safety standards.

Schedule preventive maintenance to extend the lifespan of the cable tray system. By sourcing materials from trusted suppliers and following standardized installation procedures, grid cable trays in the DRC can be installed efficiently, safely, and in compliance with international electrical standards.
