Fire protection for cables and cable lines

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

Why is fire protection for cable penetrations necessary?

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).

Purpose of fire protection:

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

How to choose fire protection?

✅   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

What happens to protected cable during a fire?

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.

Fire protection methods

Fire-resistant ducts constructed of specialized boards offer the highest level of reliability.
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.

How we do the work

Route survey. We look at where the cables run, how many are in each bundle, the trays, penetrations through walls and floors, and access to the routes.
Calculation. Based on the design and the survey results we calculate the scope of work and material consumption and agree the timing with the site schedule.
Preparation. We clean cables and trays of dust, oil and dirt: the compound must be applied to a clean surface.
Application. We apply the compound along the entire length of the protected section at the required rate and treat penetrations through walls and floors separately.
Inspection and handover. We check the thickness and continuity of the coating and hand over as-built documentation for acceptance.

Free trial area

We will treat a trial section of the cable route on your site free of charge — you can assess the result before signing the contract.

Over 20 years of fire protection experience, our own crews, ISO 9001 and ISO 45001 certified, all necessary permits. We work across Uzbekistan.
