Underwater TV Cable with 3 Coaxial Conductors | Tri-Coax Subsea

Underwater TV cable with 3 x 75 ohm coaxial conductors for multi-camera ROV systems. PUR jacket, shielded, supports 3 simultaneous video channels. Custom lengths available.

Product introduction

Underwater TV Cable with 3 Coaxial Conductors for Multi-Camera ROV Systems

This multi-coaxial underwater cable houses three independent 75-ohm coaxial channels within a single PUR-jacketed cable assembly. It enables simultaneous transmission of three video streams from multi-camera ROV configurations -- such as front, rear, and manipulator-mounted cameras -- reducing cable management complexity and drag compared to running separate cables.

Parameter Specification
Coaxial Channels 3 x 75 Ohm
Coax Construction Individually shielded with foil + braid
Power Conductors Optional (per configuration)
Jacket Material Polyurethane (PUR)
Voltage Rating 300V RMS
Temperature Range -30°C to +80°C
Depth Rating Up to 4,000 m
Shielding Per-coax foil + braid, plus overall screen

Key Applications

  • Multi-camera ROV systems (front/rear/pan-tilt)
  • Subsea 3-channel CCTV installations
  • Offshore platform multi-camera monitoring
  • Subsea production system visual inspection
  • Underwater research vehicles with stereo cameras

Frequently Asked Questions

Is crosstalk between the three coax channels an issue?

No. Each coaxial channel is individually foil and braid shielded, and they are separated by insulating filler within the cable. Inter-channel isolation exceeds 60 dB, ensuring clean independent video signals on all three channels.

Can additional signal or power conductors be added to this cable?

Yes. Custom configurations combining 3 coaxes with power conductors (e.g. 2 x 18AWG) or signal pairs are available. Provide your conductor requirements and we will produce a custom design.
