Electro-Mechanical Cables

Hybrid cables that combine power, signal, and strength for towed, lifted, and deployed systems.

Rochester Cable designs and manufactures hybrid electro-mechanical cables that combine electrical conductors, optical fibers where needed, and high-strength load-bearing members in a single construction. These designs are built for systems that tow, lift, or deploy equipment in harsh subsea, offshore, and industrial environments while maintaining reliable power and data links.

Instead of an off-the-shelf part-number catalog, we engineer each electro-mechanical cable around your application. Explore the typical electro-mechanical roles and configurations below to see how our designs fit into your system.

When to choose electro-mechanical cables

Electro-mechanical cables make sense when a single cable has to carry both power and signals and support the mechanical load of the equipment being deployed or towed.

Consider electro-mechanical designs when:

  • Your system tows, lifts, or deploys equipment using a winch or handling system.
  • The cable runs over sheaves, drums, or other tension-bearing hardware as part of normal operation.
  • You need power, control signals, or data carried through the same cable that takes the mechanical load.
  • Cables operate in subsea, offshore, or other harsh environments where both mechanical and electrical performance are critical.

Performance in harsh environments

Electro-mechanical cables must handle repeated cycles of load, bending, and handling while maintaining electrical and, where used, optical performance. Rochester Cable’s designs focus on long-term performance across mechanical and electrical domains.

Integrated Strength and Data

Cables that combine load-bearing elements with conductors and, where applicable, fibers to avoid multiple separate lines.

Designed for Dynamic Loads

Constructions that account for towing forces, vessel motion, and deployment and recovery cycles.

Bend and Handling Factors

Designs that factor in sheave diameters, bend radii, and handling practices during normal operation.

Configured for the Environment

Material and construction options chosen to address immersion, pressure, temperature, and abrasion, depending on the project.

What we can build in the hybrid cable family

Rochester Cable offers a range of hybrid electro-mechanical constructions that can be configured to meet the load, distance, and signal requirements of your system.

Configurable Designs

Hybrid cables can be configured around conductor sizes, fiber counts, overall length, and required mechanical characteristics to match the system they will run in.

Tether and Umbilical Variants

Design options for ROV tethers and umbilicals, with choices in strength members, armor systems, and construction to align with target breaking strength, diameter, and weight in air and water.

Towed and Deployed System Variants

Hybrid cable designs suited for towed arrays and other deployed systems, where power, control, and data have to share a single cable over longer distances.

Integration into Existing Systems

Cables that can be configured to work with existing winches, sheaves, terminations, and handling equipment, helping hybrid electro-mechanical cables fit into current operating setups.
