Cable ducts are for protecting and sorting small to medium groups of cables. They are perfect for a few data cables or a power line in a wall. They are designed for large amounts of power. 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. They ensure cables are installed neatly, reduce the risk of damage, and make maintenance or upgrades easier.
