    in simplest terms, a duct bank provides a protected pathway for buried electrical or data cables. the cables are housed within pvc pipe called conduits, which are then encased in steel reinforced concrete. duct banks may carry cable a short distance, such as under a road or longer distances, such as carrying electrical power from a power generating

    duct bank design is an exercise in thermal analysis. the allowable separation of the conduits has to do with the material between the conduits, and the current in each conductor. additional constraints are burial depth, duct size, cable grouping, soil thermal resistivity, soil temperature, and additional heat sources, i.e. circulating water pipes, steam pipe, or other duct banks/conductors.

    a duct bank can be very large say in a matrix of 12 by 10 and needs both strength and protection from concrete. cable ducts must remain separated from each other throughout the service life and electric cables are expensive. the ducts are spaced very close to each other and need steel reinforcement to provide adequate strength.
