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
Anti-seawater cable — acid/alkali resistant, highly flexible mobile cable product details: I. Product photos II. Core advantages: Resistant to weak acid/alkali and seawater corrosion, all-scenario protection. The outer sheath is made of specially modified polyurethane (PUR) material. According to professional testing, after soaking in weak acid/alkali solutions with pH value 4-10 for 1,000 hours and in 3.5% sodium chloride (seawater simulation) solution for 1,500 hours, the surface shows no damage and no performance degradation, effectively resisting the erosion of weak acid/alkali substances and chloride ions in seawater. Whether in coastal chemical wastewater environments or offshore aquaculture areas, it can maintain stable operation.
Highly flexible design, worry-free for mobile scenarios: The interior adopts multi-strand finely stranded oxygen-free copper wire conductors, combined with high-elasticity TPE insulation material and Kevlar tensile fiber braided layer, giving the cable excellent flexibility. Tests show that it can withstand more than 8 million bending cycles, with a minimum bending radius of 6D (D is the cable outer diameter). In drag chain systems, underwater robots and other frequently moving or bending working conditions, it does not break the core or the wire, meeting high-dynamic application requirements.
Efficient and stable transmission, reliable performance: The conductor complies with VDE 0295 Class 6 standard. The low resistance and low capacitance design ensures efficient power and signal transmission. Optional single-layer or double-layer shielding structure (aluminum foil shielding + tinned copper wire braid) with shielding coverage ≥90% effectively resists electromagnetic interference, ensuring stable data and power transmission in scenarios such as underwater detection equipment and automated production lines.
Wide temperature range, durable, safe and environmentally friendly: The working temperature range reaches **-40℃~90℃**, and it can be used normally in cold sea areas and high-temperature working environments. Halogen-free, no heavy metal additives. Insulation resistance ≥500MΩ/km, voltage withstand level up to 300/500V, flame retardant grade complies with IEC 60332-1 standard, safe and reliable.
3. Application scenarios: Marine aquaculture and monitoring: Used for power supply and signal transmission of underwater aerators and water quality monitoring equipment, resistant to seawater and aquaculture chemical corrosion, adapting to equipment movement needs.
Coastal chemical and environmental protection projects: In the wiring of pumps, mixers and other equipment handling weak acid/alkali wastewater, it resists corrosion while meeting the high flexibility requirements of frequent equipment start-stop.
Port loading/unloading and ship equipment: Suitable for port crane drag chain systems and ship deck mobile equipment connections, coping with sea breeze salt spray and engine room oil pollution environments.
Underwater detection robots: Provides power and control signal transmission for underwater robots. The highly flexible design matches the robot's flexible movement characteristics.

Customization services: Specification customization: supports various wire diameters from 0.14mm² to 50mm², with flexibly configurable number of cores (2 to 60 cores), adapting to the power needs of different equipment.
Special performance customization: can customize high-temperature resistant type (up to 125℃), low-temperature resistant type (down to -60℃), anti-torsion type and other special performance cables.
2. Performance and Technical Indicators
Rated voltage 0.6/1kV; longitudinal water resistance up to 300m water depth; applicable temperature range -20℃ to +80℃; salt spray resistance test no less than 1000h, excellent hydrolysis resistance, can be used stably in marine environments for a long time.
