What Is a Duct Bank?
A duct bank refers to a group of electrical conduits that provide pathways and protection for electrical wiring. Duct banks are typically installed underground for large buildings that require substantial wiring.
Duct banks not only protect the enclosed cables from damage, but they also consolidate and conceal the building's series of wires. Bundling cables with a duct bank also streamlines future construction projects because the cables are consolidated and bundled to create a clear passageway. This consolidation allows property owners to upgrade or repair existing wiring without undergoing lengthy excavation projects.
Duct banks are either composed of plastic, metal or fiber depending on the associated electrical product. Standard duct banks utilize either concrete or metal casing to protect the enclosed wires. Duct banks are constructed in a multitude of sizes and methods to accommodate conduits of various sizes. Each electrical conduit is comprised of a PVC pipe to hold insulated wiring. Conduits are grouped together and covered to prevent damage from water or physical stress.
Electrical conduits are installed underground between buildings to streamline the installation of communication and power cables. Duct banks are simply a series or assembly of electrical conduits to consolidate substantial amounts of electrical cables and wires.
