A cable tray is a structural system used in electrical installations to support, organize, and protect electrical cables and wires. It provides a safe and neat pathway for routing power, control, and communication cables in buildings and industrial environments.
Description
Cable trays are typically made from materials like:
• Galvanized steel
• Stainless steel
• Aluminum
• PVC (for light-duty applications)
They are installed overhead, along walls, or under floors to carry cables instead of using traditional conduit pipes.
Types of Cable Trays
1. Ladder Cable Tray
• Looks like a ladder with two side rails and rungs
• Best for heavy cables and good ventilation
2. Perforated (Ventilated) Cable Tray
• Has holes for airflow
• Suitable for medium-weight cables
3. Solid Bottom Cable Tray
