Bridge Aerial Cable
These multi-conductor cables are designed for unsupported aerial use between structures and are offered in 600- and 2000-volt options. They comply with all requirements for installation on bascule, lift, and swing bridges, as well as for direct burial applications. The cables can accommodate a combination of power, control, and signal circuits, including fiber-optic components, with up to 125 conductors and a maximum diameter of 5 inches (12.7 cm). Additionally, an empty conduit can be integrated into the cable design.
These cables have been developed through a long-standing relationship with a diverse range of end-users and specifiers, including local Departments of Transportation (DOTs), architects, engineers, and contractors. They are engineered to perform reliably under the most challenging conditions.
The features detailed below are standard but can be modified upon request to meet specific application requirements.
Specifications and Ratings
