Common cable trays should be converted into separate cable trays
Instrumentation, signal, and telecommunications cabling should be separated from power cabling. This can be accomplished by a separate cable tray system or by a divider within a cable tray. This segregation helps to prevent electrical interference, signal degradation, and potential safety hazards. Here's what you need to know: Cable Types: Only use. Why It Matters: High‑voltage and limited energy circuits routed too closely can cause cross‑talk, distortion, or packet errors, especially in dense cable trays or congested ceiling spaces. Well suited for power and large control cables.

What is the function of galvanized cable trays
Common cable trays are made of galvanized,, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication. When galvanized tray is cut to length in the field, usually the cut surface will be painted with a zinc-rich compound to protect the metal from corrosion.
