Underwater Cables

A Variety of Applications

At Northwire we build a variety of custom underwater cables. Whether the application is for freshwater or saltwater, chemicals, solvents or all of the above, Northwire has your cable solution.

Reliable Performance

Northwire uses unique compounds formulated to withstand the effects of long term immersion in aqueous fluids. In addition to these insulation and jacket extrusions, Northwire provides an assortment of fillers, tapes and other compounds that protect the cables from water penetration. In the event that the cable is cut or impaled, these materials will absorb and swell, resulting in the blockage at the point of entry.

A Variety of Uses

Underwater cable uses include camera and video systems, sonar, control, well, sewer and geophysical applications.

Consider Your Requirements

For cables that will live in submersed environments, a few unique considerations apply.

Considerations for cables that will be submersed include:

Materials must be compatible with fluid environment.
Fluid blocking components may be desirable to block migration of fluid (should the outer jacket become compromised).
Strength members may be desirable to isolate stress from electrical components.
Buoyancy (neutral, positive and negative).
Temperature of liquid environment.
Special Markings on Cable (for depth for example).

In addition to the above, all the usual discussion items relating to custom cable apply. Included in these are conductor strandings and platings, insulating options, electrical performance requirements, colors, conductor marking options, shielding necessities and jacketing options, to name a few.

Since 1972, Northwire has been designing and building custom cable solutions for the most demanding underwater applications. Please contact Northwire at 1.800.468.1516 or +1 715.294.2121.
