Ireland Long-Span Cable Trays

Long-span cable trays in Ireland are typically constructed using steel or wire mesh ladder systems, designed for heavy-duty loads, optimal ventilation, and flexible installation over extended distances.Types of Long-Span Cable TraysSteel Cable Ladders: Ideal for heavy-duty power cables and long runs, steel ladders provide maximum support and ventilation. The long rung spacing allows full free-air rating of cables, preventing overheating and ensuring efficient current flow . Wire Mesh Basket Trays: Lightweight and flexible, wire mesh trays are suitable for medium-duty applications. They allow excellent cable ventilation, reduce dirt accumulation, and can be easily cut and fitted onsite with minimal planning . Perforated Steel Trays: These are U-shaped trays with perforated bottoms and folded sides, available in light, medium, and heavy-duty constructions. Perforations allow cooling and easy cable fixing using ties or clips .Materials and ProtectionHot-Dip Galvanised Steel: Provides corrosion protection through a zinc coating, acting as a physical barrier and offering sacrificial protection at cut edges .Pre-Galvanised Steel: Carbon steel sheet immersed in zinc before fabrication, suitable for indoor and less corrosive environments .Powder Coating: Optional for aesthetic or additional corrosion resistance .Installation ConsiderationsSupport Spacing: Long-span trays require careful calculation of support intervals to prevent sagging. Steel ladders and heavy-duty trays allow spans of several meters depending on cable load .Connection Systems: Modern systems like OBO GR-Magic® allow tool-free, fast connections, reducing installation time and labor costs while maintaining stability and safety .Flexibility: Modular systems enable side-loading of cables and easy integration with existing infrastructure .Compliance: Ensure all fasteners, brackets, and rods meet EN ISO standards for galvanisation and corrosion protection .Suppliers and Solutions in IrelandExcel Electric: Offers EZFIT steel cable trays and trunking systems, with options for light, medium, and heavy-duty long-span installations .Niedax: Provides RLVC systems, wire mesh baskets, and cable ladders suitable for industrial and commercial long-span applications, with customizable dimensions .OBO Bettermann via Solutions.ie: Offers fire-rated and standard steel containment systems with innovative connection systems for rapid installation .Local Installers: Companies like Dm Electric Services and Peter Curran Electric provide design, installation, and maintenance services for cable tray systems across Ireland .Best PracticesPlan support intervals based on cable weight and tray type.Use perforated or ladder trays for heat dissipation in high-current applications.Select corrosion-resistant materials for outdoor or humid environments.Consider modular, tool-free systems to reduce installation time and future maintenance.Ensure compliance with Irish and European electrical standards for safety and durability. By selecting the appropriate tray type, material, and installation method, long-span cable tray systems in Ireland can achieve efficient, safe, and scalable cable management for industrial, commercial, and institutional projects.
