Why Our Neutral Buoyancy Cable Excels in Subsea Sensor Networks
For long-term ocean monitoring, cable integrity is critical. Our Neutral Buoyancy Cable combines anti-corrosion protection, robust shielding, and precise neutral buoyancy to prevent vertical stress on sensors and moorings.
Key benefits include:
-
Advanced anti-corrosion barriers: specialized polymers and sacrificial layers for saltwater and microbial protection
-
Multi-layer shielded structure: blocks EMI/RFI from nearby power lines or environmental sources
-
Extended service life: typically 15–25 years in continuous submersion
-
Precise neutral buoyancy: eliminates vertical tension/compression on seafloor installations
-
Low-maintenance design: resistant to biofouling and chemical degradation
-
High signal integrity: ideal for acoustic, seismic, and environmental sensor arrays
