Italian fireproof cable trays are designed for high fire resistance, durability, and compliance with international safety standards, ensuring reliable protection of electrical and instrumentation cables in industrial and infrastructure applications.

Material and Construction

Italian manufacturers, such as Schiavetti Tekno (part of Spina Group), produce cable trays using stainless steel, hot-dip galvanised steel, and aluminium, providing excellent corrosion resistance, mechanical strength, and long-term durability in harsh environments. Fireproof cable trays often include closed-bottom (FC) designs to protect cable insulation and perforated or ladder types to allow ventilation while maintaining fire safety.

Fire Resistance Features

Fireproof cable trays are engineered to maintain cable functionality during fire events, allowing critical systems to operate long enough for safe shutdown or evacuation. They may incorporate fire-resistant wraps, blankets, or coatings, such as aluminium-encapsulated FireMaster® blankets, which provide 30 minutes of hydrocarbon fire protection for instrument control cables. These systems are tested according to ASTM E1725-95, ASTM E119, ASTM E1529, and EN 1363-1 standards, ensuring reliable performance under controlled fire conditions.

Design and Installation Features

Italian fireproof cable trays are designed for modular assembly, with joints and slots that accommodate thermal expansion without damaging the tray or cables. Electrical continuity is ensured through grounding holes and copper bonding jumpers, while accessories like elbows, junctions, and supports provide flexible routing and secure installation. Protective covers are available for outdoor and indoor use, shielding cables from dust, moisture, UV radiation, and mechanical impacts.

Compliance and Testing

These cable trays comply with European (EN) and international (UL) standards, and manufacturers conduct extensive fire testing with installed cables to verify performance. Fire-resistant materials are selected to minimise toxic flue gases and maintain structural integrity during fire, ensuring safety for both personnel and critical electrical systems.

Applications

Italian fireproof cable trays are widely used in industrial plants, energy infrastructure, hospitals, airports, power stations, and offshore facilities, providing reliable cable management and fire protection in demanding environments. In summary, Italian fireproof cable trays combine robust materials, fire-resistant coatings, modular design, and compliance with international standards to ensure safe, durable, and reliable cable installations in both industrial and critical infrastructure settings.
