Targeting the networking demands of 3,500m deep-sea neutrino detection arrays, 5 sets of domestic wet-mate connectors have finished dynamic mating tests.
The trial verified electrical conduction, seawater insulation and optical communication functions, providing critical data for the finalization of high-end domestic wet-mate connectors.
It has conquered three core technical systems: 110MPa full-ocean-depth high-pressure sealing, precision mating and long-term biofouling resistance.
It realizes plug-and-play high-reliability connection for 10,000-meter-level hadal zones, filling the domestic gap in full-ocean-depth connectors.
Released YSG‑JL/YM series connectors, adopting a ratchet anti-loosening + sliding docking structure with strong vibration resistance and low mating torque.
Suitable for air-water-land cross-medium unmanned system cluster applications; insulation resistance ≥5000MΩ, operating temperature: -55℃ ~ +125℃.
The 12-core optoelectronic connector achieved stable mating over 30 times at kilometer-level deep sea, with optical insertion loss < 0.25dB (50% better than international standard) and insulation resistance > 50GΩ (5 times the international standard).
It breaks the 40-year overseas monopoly, with independent controllability of core sealing materials and anti-corrosion housings.
Established a time-dependent thermoelectric dynamic electric field molecular ionization model, revealing the mechanism of streamer discharge in high-voltage insulating oil.
Proposed adopting 0.1–0.2mm PTFE coating to restrain streamer growth, or epoxy resin capacitance grading to reduce electric field peak value, solving the insulation failure problem of 3,000-meter-level HVDC connection.
Product lineup covers 12-core electrical, 12-core optical and 16-core optoelectronic hybrid types, supporting 25-year maintenance-free operation at 4,000m deep sea.
Its optoelectronic core density reaches world-leading level, compatible with ROV automatic mating, and has been applied in offshore oil & gas and deep-sea observation networks.
Launched MORGRIP® 3000Ri series, one design compatible with multiple specifications of 8″/14″/20″ thin-wall pipelines for deep-sea pipeline emergency maintenance.
Equipped with interchangeable sealing components to reduce customization costs, passing factory acceptance and water pressure tests.
