Reliable Performance In Xtreme Environments

Winchester’s team of cable designers work closely with our customers and their application requirements to provide the most reliable cable solutions for today’s high performance ROVs used in oil and gas exploration, defense, and a host of marine applications.

High Quality and Reliability

Winchester Interconnect manufactures a large range of ROV tether cables from small inspection handheld vehicles to large work class ROV’s in either neutral buoyant or negative style designs for various applications. We use specifically designed insulations, fiber-optic components, Kevlar, Vectran and specially formulated low density plastics to meet critical dimension controlled cable designs. Our cable designs are created for optimizing the mechanical, electrical and optical performance in demanding subsea projects.

Testing New Designs and Configurations

Winchester performs cable integrity test validation for each tether and umbilical. New design and test programs can be offered with extensive evaluation of cable strength layers such as ultimate break strength, bend cycling fatigue, low tension cycle fatigue, torque and rotation, hydrostatic, as well as all optical, electrical HiPot and third party certifications are available upon request.
