Shanghai Suoqi Zero-Buoyancy Cable, 3 Twisted Pairs, 6-Core Signal Cable, Double-Layer Sheath Protection, Product Details
1. Product Overview
Shanghai Suoqi zero-buoyancy cables are specially designed for harsh underwater environments, featuring 3 pairs of twisted 6-core signal cables designed for underwater data and signal transmission. They are widely used in underwater robots, marine survey equipment, underwater monitoring systems, and other fields, serving as a key connection cable to ensure stable operation of underwater equipment.
2. Core Advantages
Zero buoyancy characteristics: Through special processes and material formulation, the cable can maintain zero buoyancy in water, neither floating nor sinking. This effectively prevents the operation of underwater equipment from being affected by the cable's own weight, ensures the accuracy and stability of equipment operations, reduces energy consumption and mechanical wear, and extends service life.
3 twisted pairs, 6-core signal cable: The 6-core wires are precisely paired and twisted to reduce signal transmission interference, ensuring high-speed and stable signal transmission. It has a fast transmission rate and strong anti-interference capability, suitable for scenarios with high requirements for transmission quality, such as high-definition video signals and complex control commands, providing stable and reliable data transmission.
Double-layer sheath protection:
Inner sheath: Made of specially formulated material with high toughness and excellent waterproofing, tightly wrapping the conductors to provide basic waterproofing and insulation protection, preventing water penetration and ensuring stable signal transmission.
Outer Sheath: Made of imported high-strength polyurethane material, wear-resistant, oil-resistant, acid and alkali-resistant, and resistant to seawater corrosion. It can withstand underwater complex environmental erosion and mechanical external impacts, ensuring long-term stable operation of the cable.
3. Product Structure
Conductor: Carefully selected multi-stranded finely twisted oxygen-free copper wires, with high purity and low resistance, ensure efficient transmission of signals and electricity, and offer excellent flexibility, suitable for frequent bending and movement operations of underwater equipment.
Insulation layer: Each wire core is coated with a special insulation material, which has excellent insulation performance and a low dielectric constant, reducing signal transmission loss, effectively isolating each wire core, and preventing signal crosstalk.
Shielding layer: Built-in tinned copper wire braided shielding layer with a shielding density of over 85%, which can effectively block external electromagnetic interference, ensure signal purity, and guarantee accurate transmission of underwater equipment control commands and reliable data collection.
Tensile element: High-strength tensile materials such as Kevlar fibers are evenly distributed along the axis inside the cable to improve the overall tensile strength of the cable, providing reliable protection for the cable during underwater equipment towing and lifting operations, and preventing the cable from breaking due to excessive force.
Sheath: The inner and outer double-layer sheaths work together. The inner sheath focuses on waterproofing and insulation, while the outer sheath emphasizes wear resistance, corrosion resistance, and mechanical protection, providing comprehensive, multi-layered protection for cables.
4. Performance Parameters
Working voltage: 300/500V, meeting the voltage requirements for power supply and signal transmission of most underwater equipment.
Test voltage: 3000V, strictly tested at the factory to ensure the cable's insulation performance and safety.
Insulation resistance: ≥ 20MΩ/km (20°C), excellent insulation performance, reducing leakage risk and ensuring equipment and personal safety.
Bending radius: During mobile installation, the bending radius is approximately 7.5 times the cable's outer diameter; during fixed installation, it is about 4 times the cable's outer diameter. It has good flexibility, suitable for different installation and usage scenarios.
Operating temperature: -40℃ to 90℃, capable of functioning normally in extreme cold to high-temperature harsh environments, suitable for diverse marine environments worldwide.
Waterproof rating: IP68, capable of long-term submersion underwater, with excellent waterproof performance, ensuring stable operation of the cable in complex underwater environments.
5. Application Scenarios
Underwater Robots: Transmit control signals and collect data for underwater robots, ensuring precise operations underwater, such as exploration, salvage, and inspection.
Marine Survey Equipment: Connects marine monitoring buoys, underwater sensors, and other devices to stably transmit environmental data such as temperature, salinity, and water pressure, supporting marine scientific research and resource exploration.
Underwater monitoring system: transmits high-definition video signals, providing clear images for underwater security, aquaculture monitoring, and water conservancy facility monitoring, facilitating real-time monitoring and decision-making.
