Tray cables are fundamentally designed for use in cable trays rather than conduit. However, conduit becomes necessary when cables are underground and not direct-burial rated, in areas of high mechanical threat or when extra environmental protection is justified. Cable trays are more preferable in large buildings or factories since they are not closed and can be readily repaired. Some tray cable, with XLPE insulation (cross-linked polyethylene), is sunlight resistant and suitable for installation in free air and hazardous locations - although this goes according. They're excellent for protecting individual circuits in harsh or public areas, but they're labour‑intensive and slower on large cable counts.
