Shanghai Suoqi Cable Co., Ltd. has long been specialized in the field of special flexible cables. Below is a professional interpretation of anti-seawater cable from three dimensions: material structure, performance advantages and application scenarios.
1. Material and Structural Parameters
Corrosion-resistant anti-seawater cable product details. 1. Real product photos. 2. Core advantages. Super corrosion resistance, defying erosion in seawater environments: the outer sheath adopts a composite polymer corrosion-resistant material. Tested by an authoritative institution, after 2000 hours of immersion in 3.5% sodium chloride (simulated seawater) solution, the surface shows no cracks or swelling, and the tensile strength retention rate is ≥ 95%, effectively resisting chemical corrosion from chloride ions, sulfates and other substances in seawater. Meanwhile, it also exhibits excellent tolerance to acid and alkali components in industrial wastewater and to chemical solvents, suitable for highly corrosive environments such as oceans, chemical plants and salt mines.
Fully sealed protection, long-lasting waterproofing and impermeability: the overall protection rating of the cable is IP68, capable of long-term stable operation at an underwater depth of 15 meters; the multi-layer sealed structure design prevents seawater from penetrating into the interior. The outer sheath hardness reaches Shore 90A with excellent wear resistance; even under harsh conditions such as reef friction and seabed sediment scouring, the protective layer remains intact, extending cable service life.
Efficient and stable transmission, outstanding and reliable performance: the conductor is made of high-purity tinned oxygen-free copper wire, anti-oxidation treated, with excellent conductivity and oxidation resistance; combined with low-loss, high-insulation cross-linked polyethylene (XLPE) material, it effectively reduces signal attenuation and power loss during transmission. Whether supplying power to offshore wind turbines or supporting high-speed data transmission of underwater detection equipment, it ensures stable and efficient performance.
Wide-range environmental adaptability, dual safety and environmental certifications: the working temperature range covers -50°C to 105°C, operating normally both in the extreme cold of polar seas and the high temperature of tropical oceans. It contains no lead, mercury or other harmful substances. Insulation resistance ≥ 1000 MΩ/km; voltage rating up to 8.7/15kV; flame retardancy complies with the IEC 60332-3 standard — trustworthy safety performance.
3. Application scenarios. Marine energy development: suitable for submarine cable laying in offshore wind farms and for connections of tidal power generation equipment, ensuring stable energy transmission.
Port and shipbuilding industry: used for port cranes, ship ballast water treatment systems and bilge cable wiring, resisting sea wind salt spray and engine room oil pollution erosion.
Underwater detection and engineering: provides reliable power and signal transmission for underwater robots, submarine pipeline monitoring equipment, and inspection devices for sea-crossing bridge pile foundations.
Chemical and salt mining fields: used as equipment power supply and control cables in corrosive environments at chemical plants and salt mining sites.
2. Performance and Technical Indicators
Rated voltage 0.6/1kV; longitudinal watertight performance up to a water depth of 300m; applicable temperature range -20°C to +80°C; salt spray test resistance of no less than 1000h, excellent hydrolysis resistance, suitable for long-term stable use in marine environments.
3. Application Scenarios
Anti-seawater cables are widely used in industrial automation, lifting and transportation, ports and docks and other fields.
