An electrical cable tray system serves as a rigid structural raceway designed to support and route electrical cables and wires. Unlike a simple wire trough, which is typically a covered channel for shorter runs, cable trays provide a comprehensive support system for complex wiring paths over long. Proper cable pulling protects the physical and electrical integrity of the entire structured cabling system, ensuring every run performs to its rated bandwidth and PoE load. Below cable pulling procedure will.
