Cable trays replace conduits
Tray cable in mesh trays reduces labor compared to conduit. Conduit requires more time, materials, and pulling effort. The decision on whether to use a cable tray or a conduit lies on the scale of the job as well as the amount of heat the wires will generate. They're excellent for protecting individual circuits in harsh or public areas, but they're labour‑intensive and slower on large cable counts. Each system offers unique benefits depending on the environment, cable load, and future accessibility. 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. However, in recent years, wire mesh cable trays have emerged as a compelling alternative, particularly for commercial, industrial, and smart building applications.
