Copper and Instrumentation Cables

Robust copper cables for power, control, and instrumentation in harsh environments.

Rochester Cable produces single-conductor, multi-conductor, and coaxial copper cables for power, control, and instrumentation in harsh environments. These cables are used both as standalone runs in plant, topside, and surface systems, and as copper elements within larger subsea umbilicals and hybrid cable assemblies. 

Instead of an off-the-shelf part-number catalog, we work from proven copper and instrumentation designs and tailor them to your voltage, current, electromagnetic compatibility (EMC), and environmental needs. Explore typical copper cable roles and configurations to see how our designs might fit into your system.

When to choose copper and instrumentation cables

Copper and instrumentation cables make sense when you need proven, straightforward power and control connections, often tied into existing equipment and terminations.

Consider copper and instrumentation designs when:

  • You need power or control circuits for equipment, sensors, or instrumentation.
  • You want compatibility with existing copper-based interfaces, panels, and terminations.
  • Signals can be carried over copper using established standards rather than high-bandwidth fiber.
  • Cables are routed in plant, surface, or topside systems, or in select harsh environments where suitable copper constructions are available.

Performance in harsh environments

Copper and instrumentation cables must balance electrical performance with mechanical and environmental demands. Rochester Cable designs focus on consistent power and signal transmission, with construction options that can be tailored to how and where the cable will be installed.

Electrical Performance

Constructions designed to provide stable power, control, and signal transmission for the life of the installation.

Mechanical Protection

Options for armor, fillers, and jacketing to help address abrasion, impact, or handling requirements, depending on the application.

Noise and Interference Options

Shielding and configuration options to help manage electrical noise and crosstalk in instrumentation and control systems.

Made for the Environment

Jacket and material choices aligned with expected temperature, fluids, and other environmental factors.

What we can build in the copper cable family

Rochester offers a variety of copper-based constructions that can be configured around conductor count, size, shielding, and mechanical protection.

Single-Conductor Cables

Cables for power feeds and simple circuits, with options for different conductor sizes and insulation systems.

Multi-Conductor Cables

Bundled conductors for control, signaling, and instrumentation, with options for shielding and pair/group organization.

Coaxial and Signal Cables

Coaxial and other signal-focused designs for applications that require controlled impedance or specific signal-handling characteristics.

Elements Within Umbilicals and Assemblies

Copper-based cables that can be provided as part of larger subsea umbilicals or hybrid cable systems, where they work alongside strength members, armor, and other components in a single assembly.
