Shanghai cable company's underwater flexible cable: multi-scenario adaptation design sets a new industry benchmark
1. Deep Sea Exploration and Robotics: The Perfect Balance of High Pressure Resistance and Signal Stability
In deep-sea detection scenarios, Shanghai Suo Qi's underwater flexible cables use a double-layer shielding structure (divided shielding, total shielding), paired with a tinned copper wire braided layer, effectively isolating complex electromagnetic interference in the deep sea and ensuring signal transmission accuracy for underwater robots (ROVs) and deep-sea sensors. For high-pressure deep-sea environments above 300 meters, the cable is designed with a composite water-blocking structure featuring longitudinal water-blocking adhesive-filled and transverse seamless alloy lead sleeves, with a pressure resistance rating of over 10MPa. Additionally, through the synergistic effect of aramid fiber reinforcement and Kevlar fiber woven layers, tensile strength can be customized up to 6 tons, meeting the lifting and towing needs of deep-sea equipment.
Typical Case: A marine research institution used Shanghai Suoqi underwater navigation robot cables, integrating power, signal, and optical fiber composite structures, to complete seabed topography mapping tasks in the South China Sea at a depth of 1,500 meters. The cables maintained zero-fault operation under long-term high-pressure and salt spray environments, and the signal transmission delay was less than 0.5 milliseconds.
2. Ports and Marine Engineering: Dual Breakthroughs in Corrosion Resistance and Mechanical Stress Resistance
For high-frequency mobile scenarios such as port cranes and tidal power generation equipment, Shanghai Suoqi Cable uses domestically produced polyether-based polyurethane (PUR) sheaths, which, through a special formulation optimization, have seawater corrosion resistance more than three times that of ordinary rubber, allowing them to withstand long-term erosion in high-salt fog and high-humidity port environments. In structural design, the conductors are made of multi-stranded ultra-fine tinned copper wires (compliant with VDE 0295 Class 6 standards), with a bending radius of only six times the cable outer diameter, suitable for the high-frequency bending requirements of cable drag systems. The built-in steel wire armor layer can resist mechanical impact during the movement of port equipment, and dynamic bending tests have verified that the electrical performance remains stable even after 100,000 bending cycles.
Technological innovation: To cope with the complex electromagnetic environment of the port, cables can be optionally equipped with double-layer shielding of aluminum foil micelli and tin-plated copper mesh, enhancing anti-interference capability to over -90dB to ensure precise response of the crane remote control system.
3. Submersible Pumps and Sewage Treatment: Core Competitiveness of Long-lasting Waterproofing and Chemical Corrosion Resistance
In diving pumps and wastewater treatment scenarios, Shanghai Suoqi Cables adopts a fully water-blocking structure design: the gaps between conductors are filled with water-blocking powder, the insulation layer is wrapped with a water-blocking tape, and the sheath is made of hydrolysis-resistant PUR material. The waterproof rating reaches IP68, allowing long-term immersion in sewage and chemical wastewater. To address acid and alkali corrosion in sewage, the sheath material has passed salt spray tests (no corrosion for 500 hours) and acid-alkali immersion tests (stable performance in pH 2-12 environments), with a service life more than twice that of ordinary cables. In addition, the cable can be customized with an anti-biofouling coating to reduce damage from underwater microbial growth, making it especially suitable for scenarios such as aquaculture aeration pumps.
Typical Application: In a wastewater treatment project at a certain chemical park, Shanghai Suoqi Cable has been operating continuously for 3 years in a wastewater environment containing heavy metal ions, with the insulation resistance consistently remaining above 1000MΩ, far exceeding the industry standard of 25.
4. Customized Design: Full-Dimensional Solutions from Parameter Adaptation to Scenario Reconstruction
Shanghai Suoqi relies on the advantages of the domestic supply chain to provide 7-15 day fast customization services:
Material adaptation: Adjust the sheath hardness (Shore hardness 70A-90A) according to different water depths (0-6000 meters), maintaining flexibility 112 within a wide temperature range of -40℃ to 90℃.
Structural Optimization: For the underwater heat vulcanization joint process, develop a low-modulus PUR sheath, with adhesion to the equipment interface increased by 40% after vulcanization, ensuring waterproofing 717.
Integrated innovation: Can integrate optical fiber, gas ducts, and video coaxial cables into one. For example, in an underwater archaeological project, cables simultaneously transmit power, high-definition video, and compressed air, simplifying equipment wiring complexity by 420.
Quality Assurance: All cables have passed the voltage withstand test (5 times the rated voltage), tensile test (120% of the designed tensile strength), low-temperature bending test (no brittleness at -30℃), and comply with national standards such as GB/T 5023 and JB/T 8734, with some models being 722.
V. Technological Foresight: Future Layout of Deep-Sea Energy and Intelligent Equipment
Facing emerging fields such as deep-sea oil and gas development and underwater data centers, Shanghai Suoqi is developing ultra-deepwater optoelectronic composite cables, adopting high-strength carbon fiber reinforcement layers and high-temperature-resistant insulation materials (temperature resistance up to 150°C). The plan is to launch products with a pressure resistance level of 70 MPa and a tensile strength of 10 tons by 2026, providing technical reserves for the domestic replacement of submarine cables. Meanwhile, a cable health monitoring system based on AI algorithms has entered the testing phase, capable of real-time warning for potential risks such as insulation aging and mechanical damage, further enhancing the reliability of underwater equipment.
