Moveable Bridge


Prysmian Group’s Draka brand bridge submarine cables are a time-tested solution for delivery of power and signal to and across bridges, viaducts and rivers.

Draka brand bridge submarine cables are multiconductor 600- and 2000-volt cables designed for permanent underwater and direct buried installations between structures. They meet all requirements for use on bascule, lift and swing bridges. Cables are designed to meet required combinations of power, control, instrumentation and signal circuits (including fiber optic components) of up to 250 conductors and up to 5 inches (12.7 cm) in diameter. Empty corrugated ducts (up to 2 inches) may also be built-in as an integral part of the cable for future use.

Our engineers work with the consulting engineers, contractors and end users, including the local Departments of Transportation (DOTs), ensuring that every cable construction is tailored to meet exacting bridge electrical and optical requirements. The cable types listed below are standard items; they may be modified per your request and need. All of our Draka brand bridge submarine cables are designed to meet specific application requirements.

Inside Moveable Bridge

Submarine Cables have cross-linked polyethylene (XLPE) conductors and high-density polyethylene (HDPE) for increased water resistance and mechanical strength. They are installed underwater in trenches or in conduit and can be sued for all types of bridges.

  • Meet all requirements for bascule, lift and swing bridges
  • Holds up to 250 copper or fiber conductors
  • Built-in conduit perfect for future growth
  • Can be direct buried

Aerial cables have a steel rope along the outer jacket and helically wrapped steel tape for increased strength. They are meant to be laid horizontally in the air between towers on vertical lift bridges.

  • Meet all requirements for bascule, lift and swing bridges
  • Holds up to 125 copper or fiber conductors
  • Built-in conduit is available
  • Lashed stainless steel messenger wire

Riser cables are designed to be installed vertically to bring power from the electrical source on the ground to the top of vertical lift bridges where they can power the raising mechanism directly or be connected to droop cables or aerial cables for their purposes.

  • Meet all requirements for bascule, lift and swing bridges
  • Holds up to 125 copper or fiber conductors
  • Built-in conduit is available
  • LDPE jacketing

Droop cables are designed to be flexible enough to bend and move as the bridge rises up a vertical lift bridge. This cable is used especially for bridges which are raised using a pinion system. The cable droops down from the top of the tower and rises with the span as it is raised.

  • Meet all requirements for bascule, lift and swing bridges
  • Holds up to 125 copper or fiber conductors
  • Built-in conduit is available
  • Rubber jacketing
