Anti-Seawater Cable - Underwater Equipment Waterproof Cable Product Details
1. Product Photos
2. Core Advantages
1. Excellent resistance to seawater corrosion
The outer sheath uses imported high-quality polyether polyurethane (PUR) material, which has strong resistance to chloride ions, salts, and various corrosive microorganisms in seawater. After professional laboratory tests simulating seawater environments, after continuously soaking the cable in 3.5% sodium chloride solution (simulated seawater) for 2000 hours, the outer sheath showed no swelling, cracking, or aging, with almost no degradation in physical or electrical properties, ensuring stability even during long-term use in marine environments.
2. Super waterproof sealing
The cable as a whole achieves an IP68 protection rating, allowing it to operate steadily underwater at a depth of 100 meters for long periods without water ingress. The core insulation uses a specially designed waterproof and pressure-resistant elastomer material, tightly wrapping the conductor to block moisture entry. At the same time, the cable is filled with water-blocking gel, which can provide transverse or longitudinal water blocking depending on different application needs, fundamentally preventing faults such as short circuits caused by water intrusion.
3. High flexibility and bend resistance
The internal conductor uses multiple strands of ultra-fine finely twisted oxygen-free copper wire, compliant with VDE 0295 Class 6 standards, combined with a highly elastic TPE insulation layer to give the cable excellent flexibility. Tested to withstand over 10 million bending cycles, with a minimum bending radius of only 6D (D is the cable outer diameter). Under complex conditions such as frequent underwater robot steering and chain system reciprocating motion, the cable does not break cores or wires, effectively reducing damage risks caused by frequent bending and extending service life.
4. Efficient and stable transmission
The conductor is designed with low resistance to ensure efficient power transmission and low energy loss. For signal transmission, shielding layers can be equipped as needed, such as tin-plated copper wire braided shielding mesh, with a shielding coverage rate of ≥90%, effectively resisting electromagnetic interference, ensuring stable transmission of control and data signals for underwater equipment, and meeting the requirements for real-time data return of underwater detection devices and stable operation of underwater communication systems.
5. Wide temperature range adaptability
The operating temperature range is -40°C~90°C. Whether in cold polar seas or hot tropical marine environments, the cable can function normally. Its performance is unaffected by temperature changes, making it widely applicable for underwater projects in various seas worldwide.
6. Safe and environmentally friendly
, free from harmful heavy metals and halogens, and does not pollute the marine environment during use. At the same time, insulation resistance ≥ 500MΩ/km, voltage resistance rating up to 300/500V, flame retardant rating complies with IEC 60332-1 standard, ensuring safe and reliable use.
3. Application Scenarios
Marine aquaculture: Used for power supply and signal transmission of underwater aerators, feeders, water quality monitoring equipment, etc., resistant to corrosion from seawater and aquaculture chemicals, and adapted to frequent movement and bending in water.
Underwater detection: Provides power and control signals for underwater robots (ROVs), underwater cameras, sonar detectors, and other equipment, meeting their flexible operation needs in complex underwater environments and ensuring stable data transmission.
Marine energy: In offshore wind farms, it connects internal equipment of wind turbine towers, submarine cables, and converters, ensuring stable transmission of large amounts of electricity; In tidal and wave energy power generation equipment, it serves as a key connecting cable, adapting to harsh marine conditions.
Ports and ships: suitable for port crane drag chain systems to supply power to equipment; On ships, used for wiring bilge equipment and deck machinery, resisting sea breeze salt spray and the complex environment inside the engine room.
