Shanghai Suoqi Cable Co., Ltd. is deeply engaged in the field of special flexible cables. The following provides a professional interpretation of seawater-resistant cables from three dimensions: material structure, performance advantages, and application scenarios.
Product original reference: a corrosion-resistant, seawater-proof cable
1. Materials and Structural Parameters
It can work stably at a depth of 15 meters underwater for a long time, with a multi-layer sealing structure design that prevents seawater from entering the interior. The outer sheath has a hardness of Shore 90A, offering excellent wear resistance. Even under harsh conditions such as friction with reefs and scouring by seabed silt, it can still maintain the integrity of the protective layer and extend the service life of the cable.
Insulation resistance ≥1000 MΩ/km, maximum voltage rating can reach
2. Performance Technical Indicators
Super corrosion resistance, fearless of erosion in a seawater environment
After antioxidant treatment, it has excellent conductivity and is not easily oxidized; paired with low-loss, high-insulation **cross-linked polyethylene (XLPE)** material, it effectively reduces signal attenuation and energy loss during transmission. Whether supplying power to offshore wind turbines or supporting high-speed data transmission for underwater detection equipment, it can ensure stability and efficiency.
Suitable for submarine cable laying for offshore wind farms and tidal power generation equipment connections, ensuring stable energy transmission.
3. Application Scenarios
The surface has no cracks or swelling, and the tensile strength retention rate is ≥95%, effectively resisting chemical corrosion caused by substances such as chloride ions and sulfates in seawater. At the same time, it also has excellent resistance to acidic and alkaline components and chemical solvents in industrial wastewater, making it suitable for highly corrosive environments such as marine, chemical, and salt mining areas.
The working temperature range covers **-50℃~105℃**, and it can operate normally in the severe cold of polar seas and the high temperatures of tropical oceans. Strictly follow
Used for port cranes, ship ballast water treatment systems, and underdeck cable wiring, resistant to sea wind salt spray and engine room oil corrosion.
Reliable power and signal transmission for underwater robots, underwater pipeline monitoring equipment, and pile foundation inspection devices for cross-sea bridges.
Used as power supply and control cables for equipment in the corrosive environments of chemical plant areas and salt mining sites.
