Sunkye joins hands with strategic partners to break through the connection problem between deep sea and new energy, and build a new paradigm of high-reliability sealing technology

2025-05-22

Driven by the global energy transformation and the accelerated development of the marine economy, the sealing of equipment in extreme environments has become the core pain point of industrial connectors. Sunkye recently announced that it will jointly launch a new generation of full-scenario sealed connector solutions with its technical partners. Through material reorganization and precision process upgrades, it will break the sealing reliability bottleneck of deep-sea oil and gas, new energy vehicles and 5G base stations, triggering cooperation invitations from leading companies such as Huawei and State Grid.

Sunkye joins hands with strategic partners to break through the connection problem between deep sea and new energy, and build a new paradigm of high-reliability sealing technology

Short Description:

10,000-meter-level pressure resistance and self-healing sealing technology For the marine engineering market where Sunkye focuses on layout, the titanium alloy-fluororubber composite sealing connector (compressive strength>120MPa, IP69K waterproof grade) developed by its partners achieved zero leakage and continuous operation for 18,000 hours in the 3,000-meter deep-sea drilling platform test in the South China Sea, which is 3 times longer than the life of traditional PEEK materials.

The solution uses a nano-groove self-locking structure, which allows the submarine penetrator to maintain a contact resistance of <5mΩ after 300 thermal cycles (-40°C to 175°C), meeting the iteration requirements of the communication system of China's "Jiaolong" 10,000-meter deep-sea submersible. The electromagnetic shielding enhanced rectangular connector (shielding effectiveness ≥100dB@10GHz) launched simultaneously has successfully helped Huawei Marine achieve a 28% reduction in signal loss in transoceanic submarine cable relay stations.

Green Smart Manufacturing

Breakthroughs in Recycled Materials and Low-Carbon Processes In response to Sunkye's ESG strategy, the partners reconstructed the manufacturing process of sealed terminals: introducing a 100% recycled nickel alloy stamping process to reduce carbon emissions from end-sealed components by 56%, and increasing the wastewater reuse rate to 95% through cyanide-free gold plating technology. The production line has passed the IEC 62474 hazardous substance control certification, and its 97% recyclable design of the submarine connector housing is highly consistent with Shell's "Sustainability Guide for Deep Sea Equipment", making it the exclusive supplier of the Norwegian Equinor offshore wind power project.

Certification Barrier

Military-grade stability opens up the high-end market Based on Sunkye's expansion goals in the aerospace field, the partners completed the full certification of the MIL-DTL-38999 III series ahead of schedule to ensure the performance stability of multi-pin connectors under salt spray tests (5000 hours) and mechanical vibrations (20-2000Hz). The developed graphene-modified O-ring (hydrogen embrittlement resistance life >15 years) has passed the nuclear-grade equipment verification of China National Nuclear Corporation and will be used in the fourth-generation thorium-based molten salt reactor sensor system.

Eco-win

Automotive-grade solutions define new energy safety standards. Facing the stringent requirements of the 800V high-voltage platform of new energy vehicles for sealed connectors, the two parties jointly developed a bidirectional liquid-cooled high-voltage terminal (current carrying capacity 600A, insulation strength>5kV), which uses multi-physics field coupling simulation technology to optimize the structure and reduce charging loss by 19%. The product has completed UL 2238 certification and passed the BYD blade battery module puncture test, and will soon be installed in Tesla Cybertruck high-voltage distribution system in batches.

Sunkye Global Technical Director said

"By integrating cutting-edge materials and digital twin processes, we are redefining the reliability boundaries of connectors-from the Mariana Trench to the Mars rover, from urban power grids to space Internet, sealing technology will become the 'invisible blood' of the intelligent world."
