Overview
Underwater vehicles and ROVs operate at depth under sustained water pressure, requiring cable assemblies engineered for pressure resistance and long-term submersion reliability.
Design & Construction
Pressure-Rated, Depth-Tested Construction
Solid-filled and pressure-balanced cable constructions maintain electrical integrity at operational depth without water ingress or signal degradation.
Umbilical Tether & Power-Signal Integration
Combined power and fiber-optic signal umbilical cabling links surface control stations to ROVs, integrating propulsion power with high-bandwidth video and telemetry in a single tether.
Manufacturing Process
Built under ISO 9001 process controls with pressure-cycle and continuity testing, supporting ROV and underwater vehicle manufacturers across commercial and research platforms.
Typical Applications
- ROV umbilical tether cabling
- Underwater camera and sensor wiring
- Subsea thruster power cabling
- Underwater lighting harnesses
- Subsea junction box interconnects
Common installations include ROV umbilical tether cabling, Underwater camera and sensor wiring, and Subsea thruster power cabling, where corrosion resistance and sealed, submersible-rated protection against saltwater exposure are the primary design drivers. The same base design can also be adapted for Underwater lighting harnesses and Subsea junction box interconnects with minor changes to connector type or cable length.
