Bridge Riser Cable
These are multi-conductor cables rated for 600 and 2000 volts, 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 standard features listed can be modified based on specific requests and requirements. All of these cables are tailored to meet particular application needs.
