Bridge Traveling Cable
These cables are multi-conductor types rated for 600 and 2000 volts, specifically designed for applications that involve flexing, such as on bascule, lift, and swing bridges. They meet a specific combination of power, control, and signal circuit requirements, including fiber-optic components, and can contain up to 125 conductors with 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 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 even under the harshest conditions. The features listed below are standard, but modifications can be made upon request. All cables are tailored to meet specific application requirements.
