1. Materials and Structural Parameters
Seawater-resistant Cable - High Flexibility Mobile Cable Resistant to Weak Acid and Alkali Corrosion Product Details 1. Product Photos 2. Core Advantages Resistant to Weak Acid, Alkali, and Seawater Corrosion, Full-scenario Protection The outer sheath is made of specially modified polyurethane (PUR) material. According to professional testing, after soaking in weak acid and alkali solutions with a pH value of 4-10 for 1000 hours, and in 3.5% sodium chloride (simulated seawater) solution for 1500 hours, the surface shows no damage and no performance degradation, effectively resisting the corrosion of weak acid, alkali substances, and chloride ions in seawater. Whether in coastal chemical wastewater environments or nearshore aquaculture areas, it can maintain stable operation.
Highly flexible design, worry-free in mobile scenarios. Internally, it uses multi-stranded, finely twisted oxygen-free copper conductors, combined with highly elastic TPE insulation material and a Kevlar tensile fiber braided layer, giving the cable excellent flexibility. Tests show it can withstand over 8 million bending cycles, with a minimum bending radius of 6D (D being the cable's outer diameter). In drag chain systems, underwater robots, or other frequent movement or bending conditions, it maintains continuous conductivity without breaking, meeting the demands of high-dynamic applications.
Efficient and stable transmission, reliable performance. The conductor meets the VDE 0295 Class 6 standard, and the low-resistance, low-capacitance design ensures efficient transmission of power and signals. Optional single-layer or double-layer shielding structures (aluminum foil shielding with tinned copper braided mesh) with a shielding coverage of ≥90% effectively resist 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. Operating temperature range reaches **-40°C~90°C**, suitable for normal use in cold seas and high-temperature working environments. No halogen or heavy metal additives. Insulation resistance ≥ 500MΩ/km, voltage resistance rating up to 300/500V, flame retardant rating compliant 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 agent corrosion, and adapted to equipment mobility needs.
Coastal Chemical and Environmental Protection Engineering: In the wiring of equipment such as pump bodies and agitators for handling weakly acidic and alkaline wastewater, resist corrosion while meeting the high flexibility requirements for frequent start-stop of the equipment.
Port loading and unloading and ship equipment: Compatible with port crane drag chain systems and ship deck mobile equipment connections, handling sea breeze salt spray and engine room oil contamination environments.
Underwater detection robot: Provides power and control signal transmission for underwater robots, with a highly flexible design that matches the robot's agile movement characteristics.
