Concrete Duct Banks may carry cable a short distance, such as under a road or longer distances, such as carrying communications cables and electrical power from a generating source to transmission stations, industrial and public facilities.

Reinforced concrete placed around PVC conduits protects cables from weather, seismic stress, corrosion, temperature extremes, and vandalism to prevent breakage and failure.

The conduit arrangement allows for easy cable replacement via the duct bank ends through access at utility structures or at the surface after horizontal runs turn vertical through a vertical bend or “stub-up”
