Integrated Subsea Cable Solutions: Zero Leakage, Maximum Reliability.

Professional cable overmolding and assembly services tailored for the most demanding subsea missions. Verified at depths up to 6,000m.

Mastering the Art of Subsea Connectivity: Our Core Technologies

Beyond basic wiring—we engineer robust, pressure-rated cable assemblies that guarantee signal integrity and zero-leakage performance in the deep ocean.

Precision Overmolding

Our overmolding process utilizes high-grade Polyurethane (PU) and Neoprene to create a true chemical bond between the cable jacket and the connector body. This advanced vulcanization technique eliminates potential water ingress pathways (capillary effect) at the most vulnerable junction points.

PBOF Systems

For ultra-deep-sea missions, HYSF provides specialized PBOF (Pressure-Balanced Oil-Filled) assemblies. By utilizing oil-filled hoses and compensators, the internal pressure of the cable assembly stays equalized with the external environment, preventing structural collapse at depths of 6,000m and beyond.

Hybrid Harnessing

Simplify your subsea system design with our Hybrid Harnessing service. We integrate high-power delivery, high-speed Ethernet (Cat5e/Cat6), and sensitive analog signals into a single, ruggedized cable assembly. This reduces the number of penetrators needed for your pressure hull, minimizing risk points.

Strain Relief Engineering

In ROV and AUV operations, cables undergo constant bending and pulling. Our custom-designed Strain Relief Boots (SRB) are engineered to manage the bend radius and distribute mechanical stress away from the connector termination. This prevents cable fatigue and ensures long-term reliability during repetitive launch and recovery cycles.

High-Speed Data for Deep-Sea Intelligence

Specifically engineered for high-bandwidth underwater applications, our Ethernet assemblies ensure low-latency transmission for the latest generation of subsea sensors.

Robust Power Delivery for Heavy-Duty Equipment

Designed to handle significant electrical loads without overheating, our power cables are the backbone of subsea propulsion and mechanical systems.

Pressure-Balanced Integrity for Ultra-Deep Missions

Our PBOF system utilizes specialized clear or reinforced tubing filled with compensating oil to protect internal wires from being crushed by deep-sea pressure.

Superior Protection in Harsh Saline Environments

We utilize premium Polyurethane (PU) and Neoprene outer jackets, offering the best balance of flexibility and ruggedness for dynamic underwater use.

Our End-to-End Cable Assembly & Validation Process

We follow a rigorous engineering workflow to ensure every cable harness is mission-ready for the most demanding subsea environments.

We begin with precision stripping and preparation of specialized subsea cables. Each conductor is meticulously cleaned and tinned to ensure optimal electrical contact and to prevent the "wicking" effect where water travels through the wire strands.
Step 01: Cable Preparation & Stripping 30%
To ensure zero internal voids, we use vacuum-degassing for all potting compounds. This removes microscopic air bubbles that could collapse under high pressure, ensuring the electrical integrity of the connector-to-cable junction.
Step 02: Vacuum-Degassed Potting 40%
Using our custom-built molds, we apply a high-pressure overmolding process. We create a chemical bond between the Polyurethane/Neoprene and the cable jacket, creating a secondary, impenetrable water barrier.
Step 03: Specialized Overmolding 45%
Every assembly is fitted with a custom-engineered strain relief boot. This manages the bend radius of the cable, protecting the critical termination point from mechanical stress during ROV deployment and recovery.
Step 04: Mechanical Strain Relief 60%
We don't just test components; we test the entire system. Each completed assembly is placed in our high-pressure chambers and subjected to 60MPa (6,000m) for extended durations to verify absolute watertight performance.
Step 05: Hydrostatic Pressure Testing 90%
Every cable harness undergoes a final audit, including insulation resistance (>200 MΩ), continuity checks, and signal attenuation testing (for Ethernet/Coax) to ensure it meets your technical data sheet requirements.
Step 06: Final Electrical Audit 100%
