Cable lines are key pathways for fire propagation within a building during a fire due to their extensive network of penetrations. To ensure fire safety, regulatory documents, mandate specific fire protection measures for cables and cable lines. If installed materials do not meet these standards, supplementary fire protection for cables, lines, and their penetrations becomes essential

Fire protection prevents flame spread along cable routes. Key regulatory documents:

• RD 153-34.0-20.262-2002 (Rules for the use of fire-retardant cable coatings at energy facilities););
• Federal Law No. 123 (Technical regulations on fire safety requirements).

• maintaining the operational integrity of cable systems during a fire;
• preventing the widespread dissemination of fire throughout the building.

✅   Indoor or outdoor operating conditions, including temperature and humidity
✅   The necessary fire resistance rating (30–120 minutes)
✅   Architectural requirements (appearance, decorative requirements for structural finishes and desired finish color)
✅   Project completion timeline and budget

Properly treated cable and cable ducts:

• resist ignition for a longer duration;
• slow or halt the progression of flames;
• minimize smoke generation;
• maintain operational integrity.

This protection is vital for ensuring the security of communications systems and IT infrastructure during emergencies.

1. Fire-resistant ducts constructed of specialized boards offer the highest level of reliability.
2. Thin-layer fire-resistant coatingsapplied post-installation provide an effective and economical solution.

Conclusion: Fire protection of cable systems increases the building's fire resistance and minimizes the risk of fire spread.
