Mesh-type cable tray support

Mesh-type cable trays allow flexible, ventilated routing of cables with easy access for installation, modifications, and maintenance.Overview of Mesh Cable TraysMesh cable trays, also known as wire mesh or wire basket trays, are lightweight, highly flexible systems made from welded steel wire. They provide 360-degree access to cables, making them ideal for data centers, control rooms, and areas where frequent changes or additions are expected . The open structure allows excellent ventilation, reducing heat buildup and supporting a wide range of cable types, including power, control, and communication cables .Cabling Process StepsPlanning the RouteDetermine the main cable runs and branch points.Identify bends, risers, and drop-outs for equipment connections.Ensure the tray route avoids obstacles and maintains proper clearance from other services .Installing SupportsUse trapeze hangers, wall brackets, or ceiling mounts to secure the tray.Supports should be placed at the start and end of bends, and midway along large-radius bends to prevent sagging .Standard span spacing is typically 8 feet, but heavy cables may require shorter spans .Assembling the Tray SectionsConnect straight sections using splice plates or couplers. For optimal performance, couplers should be positioned at 1/5th of the span .Install bends, tees, and reducers as needed to maintain continuous cable routing .Laying the CablesFeed cables into the tray, ensuring even distribution to avoid overloading one side.Maintain the minimum bend radius for each cable type to prevent damage .Use hold-down clamps or cable ties sparingly to secure cables without restricting airflow .Creating Bends and BranchesMesh trays can be easily bent on-site to form horizontal or vertical turns.For branches, use tees or drop-outs to route cables to equipment below the main tray .Finishing and ProtectionInstall covers if required to protect cables from dust or debris.Ensure all cut edges are smooth or treated to prevent cable abrasion. Zinc or Geomet® coatings provide corrosion protection for steel trays .Best PracticesAvoid placing supports directly under couplers to prevent stress points .Distribute heavy cables evenly and avoid stacking multiple layers in one tray.Regularly inspect and maintain trays to ensure cables remain secure and free from damage.Select tray material and finish based on environmental conditions (e.g., stainless steel for corrosive environments) .Mesh-type cable trays provide a versatile and efficient solution for cable management, combining flexibility, ventilation, and accessibility, making them suitable for dynamic installations where cable changes are frequent.
