Recommended models for fire-retardant painted cable trays

Cablofil fireproof cable trays, EAE fire-resistant systems, and intumescent-coated steel trays are among the recommended options for fire-retardant cable management. Fire Protection Methods1. Intumescent Coatings: These are reactive fire-retardant paints applied to cable trays, often factory-applied for consistent thickness and quality.

Under fire exposure, the coating expands to form an insulating char layer, slowing heat transfer. They are ideal for new builds, hygiene-sensitive environments, and hazardous areas, and allow for easier inspection and maintenance compared to wraps. 2.

Fire Wrap Systems: These involve multilayer fire barriers installed around the tray, typically secured with stainless steel banding. They are best suited for retrofit projects, irregular routing, or harsh outdoor conditions. Wraps can be reopened for cable changes but require careful workmanship to maintain performance.

Recommended Models and Systems1. Cablofil Fireproof Cable Trays: Suitable for low and high voltage cables in construction, power, oil, gas, petrochemical, rail, and utilities sectors.

Tested to DI

N 4102-12, with fire endurance of 30, 60, and 90 minutes at temperatures up to 1000°C. Compatible with Prysmian FP400/FP600 and Draka Firetuf cables. Recommended accessories: Ellis Patents Phoenix Cable Cleats for maintaining fire integrity.

EAE Fire-

Resistant Systems: Offers a range of fireproof cable trays compliant with ISO standards for quality and safety. Models include YMzK-FB 90 E30, SMzK-FB 30-60 E30, and JS(st)H-FB 30-60 E30, suitable for ceiling and wall installations. 3.

Intumescent-

Coated Steel Trays (Various Manufacturers): Steel trays with factory-applied intumescent coatings provide smooth, cavity-free surfaces for inspection and housekeeping.

Suitable for ATE

X zones 21/22 and other hazardous areas. Performance depends on dry film thickness (DFT) control, curing, and surface preparation.

Selection Considerations

New vs. Retrofit: Intumescent coatings are preferred for new installations; fire wraps are better for retrofits. Environment: Consider exposure to sunlight, dust, or corrosive conditions.

Aluminum or stainless steel trays with coatings may be preferred in corrosive environments. Maintenance: Coatings are easier to inspect visually, while wraps require reinstallation after cable changes. Compliance: Ensure the tray system meets DIN, UL, or relevant national fire standards.

By selecting from these models and applying the appropriate fire protection method, you can achieve certified fire endurance, compliance, and long-term reliability for your cable tray installations.
