INTRODUCTION
Zero buoyancy ROV tether cable, also known as neutrally buoyant ROV umbilical cable, acts as the lifeline for remotely operated underwater robots. This seawater resistant hybrid umbilical cable integrates power transmission and signal communication inside one compact cable assembly, eliminating the trouble of separate wiring for underwater ROV systems.
Engineered with precise density matching seawater, the zero buoyancy tether neither sinks nor floats in the water column. It greatly reduces hydrodynamic drag and extra tension load on ROV thrusters, improving vehicle maneuverability and positioning stability during subsea inspection, survey, underwater pipeline checking and marine research missions.
The underwater robot umbilical cable adopts marine-grade PUR foam jacket with excellent seawater corrosion resistance, hydrolysis resistance and abrasion resistance. Built-in Kevlar strength member provides high tensile breaking load to protect inner conductors under long-distance towing and dynamic bending underwater. Multiple core configurations are available for power, control signal, video and optional fiber optic integration.
Manufactured by Shanghai Deru Cable, this hybrid power signal ROV tether cable meets CE certification. We support fully customized core quantity, AWG size, outer diameter, buoyancy parameters and cable length for inspection ROV, mini ROV and light work-class underwater robots. Our zero buoyancy ROV umbilical cable delivers stable power supply and low-noise signal transmission in harsh saltwater and freshwater underwater environments.

FAQ
A: Zero buoyancy ROV tether cable, also called neutrally buoyant ROV umbilical cable, is a seawater resistant hybrid underwater robot cable integrating power and signal lines. Its overall density matches seawater, so it keeps suspended underwater without sinking or floating. It reduces drag and tension on remotely operated underwater vehicles during subsea operations.
A: Our zero buoyancy ROV tether adopts marine PUR foam jacket for seawater resistance, hydrolysis and abrasion protection. Kevlar strength member is embedded inside to bear pulling force when towing the ROV underwater. Multi-conductor structure supports hybrid power, control signal, video and optional fiber optic transmission.
A: Yes. Shanghai Deru Cable is a CE certified manufacturer of zero buoyancy ROV tether cable. We can customize core quantity, AWG gauge, outer diameter, cable length and buoyancy parameters for mini inspection ROV and light work-class underwater robots for seawater & freshwater projects.
