Long-span cable tray systems in Ireland can be effectively supported using a variety of brackets, hangers, and fittings designed for medium- to heavy-duty applications.

Key Accessories for Long-Span Cable Trays

Stand-Off Brackets: These brackets provide secure spacing from walls or structural surfaces, essential for long-span installations. Options include 50mm, 75mm, 100mm, 150mm, and 225mm stand-off brackets, all made from pre-galvanised steel for durability and corrosion resistance, suitable for cable trays, trunking, and conduit systems . Cable Tray Hangers and Supports: Hangers are used to suspend horizontal runs of cable trays from ceilings or overhead structures, while support brackets secure trays at various points along the span. These accessories ensure stability and prevent sagging in long runs . Fittings and Couplers: To manage directional changes or join sections of tray, accessories such as tees, crosses, couplers, and swift clips are used. Ladder trays, which are ideal for heavy-duty power cables, often require solid cover fittings to protect cables from dust, water, and falling objects . Wire Mesh and Ventilated Trays: Wire mesh basket trays are lightweight, flexible, and allow excellent ventilation, reducing heat accumulation. Ventilated trays may require additional slots or holes for smaller cables, while solid-bottom trays provide maximum protection for sensitive cabling .

Material and Load Considerations

Accessories are typically manufactured from pre-galvanised steel or other corrosion-resistant finishes. The choice of accessory depends on the tray type (solid-bottom, ventilated, or ladder) and the load requirements. Long-span installations benefit from accessories that allow higher cable loads and maintain proper air circulation to prevent overheating .
