Installation of fireproof cable trays in Nigeria

Fire protection cable trays in Nigeria should be installed following technical standards for layout, material selection, and fireproofing to ensure safety, durability, and compliance.

Planning and Layout

Proper route planning is essential. Cable trays should align with the building structure, avoiding unnecessary crossings, detours, or interference with other pipelines. Routes should be as short and straight as possible to reduce cable loss and simplify maintenance. Segregation of power and signal cables is critical; high-voltage and low-voltage cables should be routed in separate trays to minimize electromagnetic interference .

Tray Type and Material Selection

• Indoor installations: Painted steel or galvanized trays are recommended.
• Outdoor installations: Hot-dip galvanized or stainless steel trays provide corrosion resistance.
• High humidity or corrosive environments: Aluminum alloy or fiberglass-reinforced plastic trays are suitable.
• Tray width and thickness must be selected based on the number and weight of cables, ensuring mechanical strength to prevent deformation under full load .

Fire Protection Measures

Fire protection is crucial to prevent flame propagation and maintain cable functionality during emergencies. Solutions include:

• Fire-resistant coatings such as FLAMMOTECT-A
• Fire protection tapes like DG-CR 0.7 These products form a protective shield around cables, delaying fire spread and enhancing resistance to environmental factors such as UV radiation, moisture, and chemicals. They are suitable for industrial plants, hospitals, airports, power stations, and substations .

Installation Accessories and Support

Cable trays in Nigeria can be installed using a variety of support systems:

• Wall brackets, ceiling hangers, trapeze mounts, and central suspension brackets
• Adjustable bends, tees, risers, and interlocking couplers for flexible configurations
• Automatic couplers and male/female interlocking systems simplify alignment and reduce installation time

Local Suppliers in Nigeria

Several Nigerian manufacturers provide high-quality cable trays suitable for fire-protected installations:

• Ned-Tech Cable Tray Ltd: Offers galvanized, ladder, perforated, and wire mesh trays with high structural strength and corrosion resistance, suitable for industrial and commercial projects .
• Legrand Nigeria: Supplies P31 cable trays with versatile accessories and high mechanical strength for reliable installations .
• Local galvanized trays: Available in standard sizes (e.g., 300mm x 50mm by 2.5 meters) for quick and safe installation .

Best Practices

• Ensure compliance with Nigerian electrical and fire safety regulations.
• Use tested fire protection products to maintain cable functionality during fire events.
• Regularly inspect and maintain trays to prevent corrosion, deformation, or fire hazards.
• Coordinate installation with other building services to avoid conflicts and ensure accessibility for maintenance . By following these guidelines, fire protection cable trays in Nigeria can be installed safely, efficiently, and in compliance with international and local standards.
