Cables are transferred from cable trays to underground

Tray cables can be buried underground, but only if they are specifically designed and rated for direct burial. National Grid. Cable trays are above-ground systems that support and organize cables. The biggest difference is how they're installed—trays are exposed, trenches are buried. Let's break down how each system works, where to use them, and what to consider. Understanding the types of cable containment systems, including trays, trunks, and conduits, helps engineers and contractors select the best solution for performance, safety, and compliance. Each system offers unique benefits depending on the environment, cable load, and future accessibility. From. Cable trays provide a support structure to lay out cables across hundreds of meters, without the likelihood of sagging or becoming tangled, or even getting in contact with the rough tunnel walls.
