Moveable Bridge Cables

Prysmian's bridge submarine cables are a reliable solution for transmitting power and signals across bridges, viaducts, and rivers. 

 

Designed and Tested for Superior Performance

Prysmian bridge submarine cables are multiconductor cables available in 600-volt and 2000-volt options, specifically designed for permanent underwater and direct-burial installations between structures. They meet all requirements for use on bascule, lift, and swing bridges. These cables can accommodate power, control, instrumentation, and signal circuits—including fiber-optic components—with up to 250 conductors and diameters reaching 5 inches (12.7 cm). Furthermore, they feature empty corrugated ducts (up to 2 inches) that can serve as an integral part of the cable for future use. 

 

Prysmian's engineering team collaborates closely with consulting engineers, contractors, and end users, including local Departments of Transportation (DOTs), to ensure that each cable construction is meticulously tailored to meet the specific electrical and optical requirements of the bridge. While the cable types listed below are standard items, they can be modified as needed. Our bridge submarine cables are designed to meet precise application requirements, and our careful construction process guarantees their quality and reliability.

Moveable Bridge Cable Solutions

Submarine cables utilize cross-linked polyethylene (XLPE) conductors and high-density polyethylene (HDPE) to enhance water resistance and mechanical strength. These cables are installed underwater in trenches or conduits and are suitable for all types of bridges. 

 

Key features include:

  • Meets all requirements for bascule, lift, and swing bridges
  • Accommodates up to 250 copper or fiber conductors
  • Built-in conduit allows for future expansion
  • Can be directly buried

Aerial cables come equipped with a steel rope encased in an outer jacket, along with helically wrapped steel tape to enhance their strength. They are designed to be installed horizontally in the air between towers on vertical lift bridges. 

 

These cables meet all specifications for bascule, lift, and swing bridges. They can accommodate up to 125 copper or fiber conductors and are available with built-in conduit. Additionally, they feature lashed stainless steel messenger wire for added support.

Riser cables are specifically designed for vertical installation, allowing them to transport power from the electrical source on the ground to the top of vertical lift bridges. These cables can either directly power the raising mechanism or connect to droop cables or aerial cables for various purposes. 

 

Key features of riser cables include:

  • Compliance with all requirements for bascule, lift, and swing bridges
  • Capacity to hold up to 125 copper or fiber conductors
  • Availability of built-in conduit
  • LDPE jacketing for added protection

Droop cables are engineered to be flexible, allowing them to bend and move as a vertical lift bridge ascends. These cables are primarily utilized in bridges that operate using a pinion system. The droop cable hangs down from the top of the tower and rises along with the bridge span as it is elevated. 

 

They meet all requirements for bascule, lift, and swing bridges, and are capable of holding up to 125 copper or fiber conductors. Built-in conduit options are also available, and the cables come with rubber jacketing for added protection.
