Fireproof strips for cable tray sealing

Fireproof sealing strips and pillows provide certified protection for cable tray penetrations, preventing fire and smoke spread while maintaining cable functionality.Overview of Fireproof SolutionsFireproof sealing for cable trays is essential to prevent flame propagation, smoke leakage, and heat transfer through penetrations in walls, floors, or ceilings. These solutions are widely used in industrial plants, hospitals, airports, power stations, and offshore facilities to ensure safety and continuity of power and communication systems .Types of Fireproof Sealing ProductsIntumescent Fireproof Pillows (e.g., AF BAGS)Certified under EN 1366-3 for up to EI 240 fire resistance.Contain intumescent compounds, thermal insulators, and water-release products inside a non-combustible fiberglass casing.Suitable for cable diameters up to 21 mm and can be inserted into thin structures without additional framing.Easily repositioned for maintenance or system modifications .Fire Protection Coatings and Tapes (e.g., FLAMMOTECT-A, DG-CR 0.7)Form a protective shield around cables to prevent flame spread.Resistant to environmental factors like UV, salt water, oil, and chemicals.Maintain cable functionality during fire, supporting reliable power and communication .Modular Sealing Systems (e.g., SLIPSIL, FIRSTO, RISE® System)Use expanding rubber inserts and sealants to create fire, water, and gas-tight seals.Can accommodate multiple cables or pipes of varying diameters.Designed for quick installation and high adaptability in existing or new penetrations .Penetration Seals (e.g., KBS® Cable Penetration Seals)Provide fire stopping for cable and pipe penetrations in walls and floors.Ensure flames and smoke cannot spread to adjacent compartments.Often combined with insulation coatings to maintain steel tube temperatures below critical limits during fire .Key ConsiderationsCertification and Standards: Ensure products comply with EN 1366-3 or equivalent fire-resistance standards.Cable Diameter and Tray Size: Select sealing strips or pillows based on cable size and tray width.Installation Flexibility: Some systems allow repositioning for maintenance, while others are permanent.Environmental Resistance: Consider exposure to moisture, chemicals, UV, or offshore conditions.Fire Rating: Choose products rated for the required EI (Integrity and Insulation) duration, typically EI 120, 180, or 240 minutes .ApplicationsIndustrial and power plantsHospitals and airportsOffshore platforms and marine environmentsHigh-rise buildings and substations Fireproof sealing strips and pillows are critical for maintaining safety, preventing fire spread, and ensuring operational continuity in cable tray systems. Selecting the right product depends on fire rating requirements, cable dimensions, and environmental conditions .
