Shanghai Suoqi Cable Co., Ltd. has been deeply engaged in the field of special flexible cables. The following provides a professional interpretation of polyurethane cables from three dimensions: material structure, performance advantages, and application scenarios.
Product Original Reference: Polyether Polyurethane (PUR) Anti-Seawater Cable, Tensile-Resistant, Wear-Resistant, Tear-Resistant
1. Materials and Structural Parameters
Polyether-Based Polyurethane (PUR) Seawater-Resistant Cable - Tensile, Wear-Resistant, and Tear-Resistant Product Details 1. Product Photos 2. Core Advantages 1. Excellent Seawater Corrosion Resistance The outer sheath is made of high-quality polyether-based polyurethane (PUR), which has super strong resistance to chloride ions, salt, and various corrosive microorganisms in seawater. According to professional laboratory simulations of seawater environments, the cable was continuously soaked in a 3.5% sodium chloride solution (simulated seawater) for 1000 hours, and the outer sheath showed no swelling, cracking, or aging. Its physical and electrical properties were almost unaffected, ensuring long-term stable use in marine environments.
2. Excellent Tensile Strength: High-strength Kevlar fibers or galvanized tensile steel wires are specially added inside as tensile elements, evenly distributed throughout the cable structure, effectively bearing external forces. Tests show that it can withstand tensile forces of up to [X] N, ensuring the cable remains intact and unbroken during underwater equipment dragging and lifting operations, greatly extending its service life.
3. The top-grade wear-resistant and tear-resistant PUR outer sheath has high hardness and strong toughness, with abrasion resistance several times that of ordinary cable sheaths. The surface is treated with a special process, providing excellent cut and scratch resistance. Under harsh conditions such as friction with reefs, scouring by seabed sediments, and mechanical collisions, it can effectively resist wear and tearing, maintaining the integrity of the cable.
4. High Flexibility and Bend Resistance The conductor uses multi-stranded ultra-fine finely 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's outer diameter), it is suitable for complex conditions such as frequent steering of underwater robots and reciprocating motion in drag chain systems.
5. 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 provided as needed, such as tinned copper wire braided shielding mesh, with a shielding coverage of ≥85%, effectively resisting electromagnetic interference and ensuring stable transmission of control signals and data signals for underwater equipment.
6. Wide Temperature Range Adaptability: The operating temperature range is -40℃ to 90℃. It can function normally in the extreme cold of polar seas and the high temperatures of tropical oceans, with performance unaffected by temperature, making it suitable for underwater projects in different seas worldwide.
3. Application Scenarios Marine Aquaculture: Used for powering and signal transmission for underwater oxygenators, feeders, and water quality monitoring equipment. Resistant to corrosion from seawater and aquaculture chemicals, and suitable for equipment that frequently moves and bends underwater.
Underwater Detection: Provides power and control signals for underwater robots (ROVs), underwater cameras, sonar detectors, and other equipment, meeting their flexible operation requirements in complex underwater environments and ensuring stable data transmission.
Marine Energy: Used for connecting internal devices in offshore wind turbine towers, subsea cables, and converters, ensuring stable transmission of large amounts of electricity; acts as a key connection cable in tidal and wave energy power generation equipment, adaptable to harsh marine conditions.
Ports and Ships: Suitable for port crane drag chain systems for equipment power supply; used on ships for below-deck equipment and deck machinery wiring, resisting corrosion from sea wind, salt spray, and complex engine room environments.
