Ladder‑Type Cable Tray Purchase Guide: Must‑Know Selection Points

2026/08/24

When power cables and control cables are laid inside the ladder‑type cable tray, it is recommended to separate them with dividers. This can effectively avoid signal interference and guarantee stable operation of control circuits.
For outdoor‑installed ladder cable trays, anti‑corrosion surface treatment such as hot‑dip galvanizing or powder coating shall be adopted. Joint sealing accessories are required to stop rainwater and dust from invading inside the tray.
Based on the total load of cables and tray dead weight, when hangers are arranged every 2 meters, the thickness of the tray side rail shall be reasonably selected to ensure long‑term safe bearing capacity without deformation.
For vertical installation of ladder cable trays, cable fixing brackets should be pre‑installed. It helps arrange and fasten cables neatly, and greatly simplifies later cable inspection, replacement and daily maintenance work.
