Fireproof cable trays in Serbia can be implemented using E-90 rated trays, fire-resistant coatings, and proper installation practices to ensure electrical continuity and safety during fire events.

Fire-Resistant Cable Tray Solutions

In Serbia, E-90 fireproof cable trays are available from local suppliers such as Pekom, providing 90 minutes of electrical circuit maintenance during fire exposure . These trays are designed to maintain power and data transmission in critical facilities like hospitals, airports, tunnels, and high-rise buildings. Internationally recognized solutions include:

• Fire-resistant coatings and tapes (e.g., FLAMMOTECT-A and DG-CR 0.7) that form a protective shield around cables, preventing flame propagation and maintaining functionality during fire .
• Panel and paste systems (e.g., Tecbor® B panels or Tecbor Preparada® Joint Paste) that cover trays and cables, tested under UNE ENV 1363-1 and UL 1709 hydrocarbon heating curves, providing 90–120 minutes of electrical maintenance .
• Fire-resistant cable support systems (e.g., Meka Pro) tested with connected cables according to EN 1363-1, ensuring structural integrity and continued operation during fire .

Installation and Compliance Guidelines

Proper fireproofing requires adherence to technical standards and installation practices:

• Tray material selection: Indoor trays typically use painted steel or galvanized steel; outdoor or corrosive environments may require stainless steel, aluminum alloy, or fiberglass-reinforced plastic .
• Segregation of cables: Power and signal cables should be routed separately to minimize interference and ensure safety .
• Fireproof coatings and sealing: Coatings must be inspected periodically for integrity, and tray passages between fire sectors should be sealed to prevent fire spread .
• Qualified installation: Fire-resistant systems must be installed by trained personnel following manufacturer instructions and local regulations .

Practical Considerations

• Critical facilities: Hospitals, airports, tunnels, and high-rise buildings benefit most from fireproof trays to maintain essential services during emergencies .
• Maintenance: Regular inspection of coatings, fastenings, and tray integrity is essential to ensure ongoing fire protection .
• Standards compliance: Using products tested to EN 1363-1, UL 1709, or equivalent standards ensures reliability and legal compliance in Serbia and the EU . By combining E-90 rated trays, fire-resistant coatings, and proper installation practices, facilities in Serbia can achieve robust fire protection for cable systems, ensuring safety, continuity of power, and compliance with international standards.
