Trenched Systems

A precast concrete trench integrated with SuperiorBus creates an efficient installation of an underground system.

Trenched systems are suited for outdoor installations where above-ground cable bus support structures would obstruct vehicle traffic or road crossings. Concrete trenching can be up to 48″ broad and 24″ deep. The system is long-lasting and can be ordered in HS20 loading for a 32,000-pound-per-axle road crossing.

Concrete trenching can be done with ventilated covers to keep the free air rating. Customer-specified conductor sizes can be modified for solid coverings and non-free air.

Within a single trench, a control cable tray can be installed alongside the principal SuperiorBus run.
