1. Materials and Structural Parameters
Seawater Resistant Cable - Hydrolysis-Resistant Polyurethane Sheathed Wire Product Details 1. Product Photos 2. Core Advantages Hydrolysis-resistant polyurethane sheaths, nemesis for seawater environments High-performance hydrolysis-resistant polyurethane (PUR) materials create outer sheaths with exceptional resistance to seawater corrosion. Professionally tested, under seawater immersion conditions, there is no significant performance degradation for 1000 hours, effectively resisting chloride ion and salt corrosion, preventing sheath cracking and aging; At the same time, it has excellent hydrolysis resistance, maintaining stable physical and electrical performance even in long-term humid and submerged conditions, making it an ideal choice for marine engineering and underwater equipment.
High protection rating, suitable for all scenarios. The cable's overall protection rating is IP68, allowing it to withstand long-term immersion at depths of 10 meters underwater without water leakage. It is also dustproof, oilproof, and acid-alkali resistant, suitable for harsh scenarios such as coastal wind power, port machinery, and seabed detection. The outer sheath surface hardness reaches Shore 85A, offering excellent wear resistance and resisting external damage such as reef scrapes and mechanical drag.
Efficient and stable transmission, reliable performance. The conductors are made of high-purity oxygen-free copper or tin-plated copper wires, paired with low-capacitance, low-loss insulation materials to ensure efficient and stable transmission of power and signals. Depending on different application needs, single-core, multi-core, and shielded cables are available, supporting high current carrying and high-speed data transmission to meet diverse needs for underwater equipment power supply and communication.
Wide temperature operation, safe and environmentally friendly. The operating temperature range reaches **-40°C~90°C**, allowing normal operation in extremely cold seas or high-temperature environments. No halogen or heavy metal additives, safe and pollution-free. Insulation resistance ≥ 500MΩ/km, voltage resistance rating up to 300/500V, flame retardant rating compliant with IEC 60332-1 standard, safe and worry-free to use.
3. Application Scenarios Offshore wind power projects: Used for internal wiring of offshore wind turbine towers and submarine cable connections, ensuring stable power transmission.
Port and Ship Equipment: Suitable for power supply and control of port cranes, ship deck machinery, and bilge equipment, resisting sea breeze and salt spray corrosion.
Underwater Detection and Monitoring: Provides reliable power and signal transmission cables for underwater robots, sonar equipment, and underwater cameras.
Aquaculture and hydraulic engineering: In fish pond oxygenators, underwater pumps, and hydraulic monitoring equipment, they are resistant to long-term immersion and complex water quality environments.
