Italian cable tray specifications

Italian cable trays are manufactured in various types and materials, with standardized dimensions, compliance with EN and UL standards, and options for perforated, ladder, and closed-bottom designs.

Types and Materials

Italian manufacturers such as Schiavetti Tekno (Spina Group) and FEMI-CZ produce cable trays in multiple types:

• Ladder trays: Ideal for medium to large cables, offering high load capacity and ventilation .
• Perforated trays: Lightweight, allow good cable ventilation, suitable for general industrial use .
• Closed-bottom trays: Provide full protection for cables, essential in environments requiring cable isolation .
• Wire-mesh trays: Flexible and lightweight, often used in complex layouts . Materials commonly used include stainless steel, hot-dip galvanized steel, aluminum, and fiberglass-reinforced polyester (GRP) for corrosion resistance and durability .

Standard Dimensions

Typical Italian cable tray dimensions include:

• Height: 100 mm
• Width: 150 mm (common), with larger custom sizes available
• Length: 3000 mm standard sections
• Thickness: 1.2 mm for standard trays Custom sizes are often available to meet specific project requirements, including compatibility with Unistrut systems and other modular frameworks .

Installation and Accessories

• Assembly: Trays are connected using M6 bolts, couplers, and fishplates for structural integrity .
• Covers: Protective covers are available for outdoor and indoor use, providing shielding against dust, humidity, rain, and UV exposure while maintaining ventilation .
• Supports and fittings: Elbows, junctions, brackets, and fixing systems ensure modularity and safe installation .
• Electrical continuity: Grounding holes and copper bonding jumpers maintain electrical continuity across tray sections .

Standards and Compliance

Italian cable trays are manufactured in compliance with European (EN) and international (UL) standards, ensuring mechanical strength, corrosion resistance, and long-term performance in industrial, infrastructure, and plant engineering applications . Specialized trays for sectors like Oil & Gas, chemical, and food industries meet stricter specifications for material thickness, load capacity, and testing .

Summary

Italian cable trays offer a versatile and standardized solution for cable management, with options for perforated, ladder, closed-bottom, and wire-mesh designs, multiple materials, and full compliance with EN and UL standards. They are supported by a wide range of accessories, covers, and custom sizes, making them suitable for both civil and industrial installations .
