Seawater Resistant Cable - Product Details of Hydrolysis-Resistant Polyurethane Sheathed Wire
1. Product Photos
2. Core Advantages
1. Hydrolysis-resistant polyurethane sheath, a nemesis for seawater environments
The outer sheath is made of high-performance hydrolysis-resistant polyurethane (PUR) material, offering exceptional resistance to seawater corrosion. Professional testing shows that under seawater immersion conditions, there is no significant performance degradation for 1000 hours, effectively resisting chloride ion and salt corrosion, and preventing sheath cracking and aging; It also 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.
2. High protection level, adaptable to all scenarios
The cable has an overall protection rating of IP68, capable of withstanding long-term submersion at depths of 10 meters underwater without water seepage, while also protecting against dust, oil stains, acids, and alkalis, making it suitable for harsh scenarios such as coastal wind power, port machinery, and seabed detection. The outer sheath surface hardness reaches Shaw 85A, offering excellent wear resistance and resisting external damage such as reef scrapes and mechanical drag.
3. Efficient and stable transmission, reliable performance
The conductors are made of high-purity oxygen-free copper or tin-plated copper wire, paired with low-capacitance, low-loss insulating 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.
4. Wide temperature operation, safe and environmentally friendly
Operating temperature range reaches **-40°C~90°C**, allowing normal operation in extremely cold seas or high-temperature environments; Strictly follows production standards, contains no halogens or heavy metals, safe and pollution-free; Passed, insulation resistance ≥ 500MΩ/km, voltage resistance rating up to 300/500V, flame retardant rating meets IEC 60332-1 standard, safe and worry-free to use.
3. Application Scenarios
Offshore wind power engineering: used for wiring inside offshore wind turbine towers and subsea cable connections to ensure stable power transmission.
Port and Ship Equipment: Suitable for power supply and control of port cranes, ship deck machinery, and hold equipment, resistant to sea wind 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.
