Cable Tray
A Cable Tray is a support system used in buildings and industrial facilities to organize and protect electrical cables. Think of it like a long metal shelf or pathway that keeps cables neat, accessible, and safe from damage. Electricians and installers use cable trays instead of running cables through pipes or leaving them loose, which makes maintenance easier and keeps the installation looking professional. You might also hear people call it a "cable management system" or "cable support system." It's an important part of any large electrical installation, especially in commercial buildings, factories, or data centers.
