Bridge Riser Cable
These multi-conductor cables are rated for 600 and 2000 volts and designed for unsupported aerial use between structures. They comply with all requirements for use on bascule, lift, and swing bridges, as well as for direct burial applications. These cables are engineered to accommodate a specific combination of power, control, and signal circuits, including fiber-optic components, with options for up to 125 conductors and a diameter of up to 5 inches (12.7 cm). Additionally, an empty conduit can be integrated into the cable design.
These cables have been developed through extensive collaboration with a variety of end-users and specifiers, including local Departments of Transportation (DOTs), architects, engineers, and contractors. They are designed to perform reliably under the most challenging conditions.
The features listed below are standard items; they may be modified as needed and as promised. All of these cables are designed to meet specific application requirements. Please get in touch with Prysmian for details.
