Anti-Seawater Cable - Underwater Equipment Waterproof Cable Product Details
1. Product Photos
2. Core Advantages
1. Excellent resistance to seawater corrosion
The outer sheath is made of high-quality polyurethane (PUR) material, which has excellent resistance to chloride ions, salt, and various corrosive microorganisms in seawater. After professional laboratory simulation tests in a seawater environment, the cable was continuously immersed in a 3.5% sodium chloride solution (simulated seawater) for 1,000 hours, and the outer sheath showed no swelling, cracking, or aging. Its physical and electrical properties were almost unchanged, ensuring stability for 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 is made of multi-strand ultra-fine precision-twisted oxygen-free copper wire, meeting the VDE 0295 Class 6 standard, paired with a highly elastic TPE insulation layer, giving the cable excellent flexibility. Tested to withstand over 8 million bending cycles, with a minimum bending radius of only 6D (D being the cable outer diameter), the cable maintains continuous connection and integrity under complex conditions such as frequent steering of underwater robots and reciprocating motion of drag chain systems, effectively reducing the risk of damage caused by frequent bending and extending its 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, a shielding layer can be provided according to requirements, such as a tinned copper wire braided shield with a shielding coverage of ≥85%, which can effectively resist electromagnetic interference, ensuring the stable transmission of control signals and data signals for underwater equipment, meeting the requirements of real-time data return for underwater detection equipment 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.
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.
