Rail Transit Sheath Technology for Seawater-Resistant Cables

In water-related environments such as coastal ports, aquaculture, and shallow sea operations, ordinary cables are corroded by seawater salt ions, causing rapid aging of insulation layers and conductor oxidation and corrosion, with prominent safety hazards. Shanghai Suoqi Seawater Protection Cables are specially designed for these conditions, with core wires twisted and tinned copper braided shielding, and specially made seawater-resistant PUR composite materials for sheaths, resistant to salt ion penetration corrosion, suitable for high-humidity offshore salt spray environments underwater. The cables feature corrosion resistance, weather resistance, and shielding, and are widely used in marine, mechanical, and underwater fields. Shanghai Suoqi cables are sold directly from the source factory, with multiple cores and specifications customized on demand, with ample stock and nationwide shipping.

Product Features

Optimizing Structure to Enhance Overall Protection Capabilities Multi-layer Protection Structure Design: The cable uses a multi-layer protective structure, consisting of conductor, insulation, shielding, inner sheath, armor layer, and outer sheath from inside to outside. Each layer works closely together, working together. The inner sheath and armor layer further block seawater, moisture, and microbial intrusion, providing extra protection for the internal conductor and insulation layers. The armor layer usually uses corrosion-resistant metal materials such as galvanized steel wire or stainless steel wire, which not only enhances the cable's mechanical strength and resists external impact and compression, but also helps prevent seawater from eroding the internal structure of the cable to some extent.

Antimicrobial Corrosion Properties: The ocean contains a large number of microorganisms, some of which attach to cable surfaces and secrete corrosive substances that accelerate cable corrosion. Shanghai Suo Qi's offshore wind power dedicated seawater protection cables use special surface treatment technologies and material selections to make it difficult for microorganisms to attach to and grow on the cable surface. Their outer sheath material naturally resists corrosive substances secreted by microorganisms, effectively eliminating the harm caused by microbial corrosion and ensuring long-term stable operation of cables in microbial-rich marine environments.

3. Customized Services to Meet Personalized Project Needs Shanghai Cable Enterprises understand that different offshore wind power projects have varying cable requirements, so they offer comprehensive customized services to meet customers' personalized needs.

Specification customization: Specifications such as cable conductor thickness and number of cores can be customized according to parameters such as the power level, operating voltage, and current of offshore wind power equipment. For high-power offshore wind turbines, conductors with large cross-sections can be customized to ensure they can withstand sufficient current to meet the equipment's power demands; For situations requiring simultaneous transmission of multiple signals or controlling multiple devices, multi-core cables can be customized, with each core transmitting different signals independently to avoid signal interference and ensure the normal operation of all equipment. For example, in some large offshore wind farms, the power of wind turbines varies by region, and cable specifications vary. Customized cables can be precisely configured according to the actual needs of each area, improving power transmission efficiency and system stability.

Custom Shape: Considering the diversity of internal space layouts and installation convenience of offshore wind power platforms, cables are available in both flat and circular shapes. Flat cables offer better installation adaptability in compact platform utility tunnels, saving installation space and facilitating wiring; Round cables perform better in scenarios requiring free rotation and bending, such as cables connecting rotatable offshore work equipment to fixed platforms. The circular design allows for smoother rotation and reduces stress concentration caused by bending. When wiring inside some offshore wind turbine trestles, flat cables can be installed along narrow spaces, reducing space occupation and improving wiring efficiency; For cables connecting offshore wind turbine blade adjustment devices and nacelles, circular designs better adapt to flexible blade movement during adjustment, ensuring stable signal and power transmission.

Frequently Asked Questions

Do seawater-resistant cables need to undergo salt spray testing?

Required. High-quality products must withstand salt spray tests for ≥1000 hours to verify the jacket's resistance to marine corrosion and microbial erosion.

Why do seawater protection cables use tin-plated copper conductors?

The tin plating layer blocks corrosion of copper caused by seawater chloride ions, and together with the PUR sheath and composite shielding, it ensures long-term underwater electrical stability.
