Product details of Shanghai Suoqi underwater ROV drone zero-buoyancy cable
1. Product Introduction
In the complex underwater working environment, Shanghai Suo Qi's zero-buoyancy cable for underwater ROV drones was born. It is custom-made for underwater ROV drones and is a key component ensuring their stable and efficient operation, dedicated to solving many problems caused by cable issues in underwater operations.
2. Core Advantages
Zero buoyancy performance: Advanced expanded polyurethane material is used as the outer sheath, and through ingenious design, the cable's specific gravity approaches that of water. In actual underwater operations, whether conducting fine underwater detection or complex salvage operations, cables can remain suspended or floating in the water without sinking due to their own weight, avoiding extra dragging burdens on ROV drones and ensuring the equipment completes tasks flexibly and precisely, greatly improving operational efficiency.
Outstanding waterproof performance: The outer sheath is made of special polymer materials and treated with special processes. Whether used for shipborne bay penetration connections, cable end faces must not allow water leakage within specified test pressure and time; or underwater environments without bare holes, cable outer sheaths must withstand water pressure. Within the specified test pressure and time, cable insulation resistance does not decrease or deform, and this cable can handle it excellently. Some products can ensure no seepage at depths of 500 meters, providing reliable waterproof protection for underwater operations.
High flexibility and bending resistance: The conductor is carefully stranded from multiple ultra-fine oxygen-free bare copper wires or tin-plated copper wires, giving the cable excellent flexibility. At the same time, optimized cable pitch, combined with special structural designs and carefully selected materials, ensures it does not core in high-frequency bending scenarios. For example, when operating in narrow, underwater spaces, the cable can easily bend flexibly with ROV drones, adapting to various complex working conditions and effectively extending service life.
Strong tensile capability: For cables operating underwater that must withstand the pulling force of equipment or heavy objects, high-strength Kevlar tensile fiber is used as the tensile center or braided for tensile resistance, forming the cable into a round shape and evenly bearing tensile forces. During underwater operation, it can withstand the tensile forces of connecting equipment or heavy objects, with breaking forces exceeding 1 ton. In special cases, tensile steel wire can be added to ensure that the cable conductor does not break the core during long-term dragging.
Outstanding anti-interference performance: The entire shield uses tin-plated copper wire braided shielding, with a shielding density of over 85%, effectively resisting external high-frequency electromagnetic interference. This ensures that underwater ROV drones maintain stable and accurate signal transmission in complex electromagnetic environments, preventing data loss or errors and guaranteeing precise device control.
Excellent environmental resistance: The special flexible polyether-type polyurethane sheath features wear resistance, oil resistance, and anti-aging properties, allowing long-term use in water without deformation or cracking. At the same time, it effectively resists seawater, acidic and alkaline corrosion, salt mist corrosion, as well as harsh environmental factors such as low temperatures, oxidation, microorganisms, radiation, and ozone, ensuring stable operation even in extremely harsh marine conditions.
3. Application Fields
Underwater ROV unmanned remote-controlled submersible operations: covering underwater imaging, underwater salvage, and underwater construction scenarios. In underwater archaeological imaging, zero-buoyancy cables ensure the ROV drone remains stably suspended at the target position, capturing clear images; During underwater salvage operations, its strong tensile resistance can withstand heavy loads, and its waterproof performance ensures the equipment operates normally in deep-water environments.
Underwater work tool connection: such as equipment with underwater mechanical arms, hydraulic cutters, etc. Neutral buoyancy allows the mechanical arm to operate more flexibly underwater, and high flexibility enables the cable to bend freely with the movements of the mechanical arm without affecting its operational precision.
Submersible motor lead wire: Used for power connection and signal transmission from submersible pumps and various underwater work appliances from surface to submersible. Stable signal transmission performance ensures stable operation of the underwater motor, with waterproof and environmental resistance guaranteeing safe use in humid and highly corrosive underwater environments.
Other underwater equipment: suitable for underwater unmanned gliders, submarine vessels, and special high-reliability environments such as ship bay connections. In ship bay connection, strict waterproofing requirements are met, ensuring stable operation of ship power and signal transmission systems.
