Scenarios such as marine monitoring and underwater aquaculture require high data transmission. Conventional cables cannot withstand seawater corrosion and humid environments, resulting in severe signal attenuation and communication interruptions. To address this pain point, Shanghai Suoqi's seawater protection network cable has been optimized in both materials and processes: the conductor is made of high-purity oxygen-free copper, the stranded wire is shielded separately by aluminum foil, the tin-plated copper is fully shielded, and the outer sheath is resistant to seawater polyurethane PUR, ensuring stable underwater signal transmission. In practical applications, the product has been recognized by customers in the underwater, mechanical, and robotics sectors for its tensile strength, corrosion resistance, and shielding performance. Supports customized design and direct shipment from stock. Please inquire for 13311756197.

Product Features

Suoqi Cable (Shanghai) Co., Ltd. specializes in designing and customizing electrical wires and cables for mechanical equipment used for extension/retraction and towing in deep water. Various specifications of underwater robot cables can be customized according to customer requirements, such as for signal transmission, power supply, and equipment control systems.

When ordering, please specify the usage environment: such as tensile load, whether it is used for mobile or fixed installation, underwater environment (freshwater or seawater) depth, etc. Underwater cables can be divided into: ① video cable; ② signal cable; ③ control cable; ④ power cable; ⑤ composite cable. Applications of underwater cables: Underwater ROV unmanned remotely operated vehicles - underwater filming, underwater salvage, underwater construction, etc. Equipped with underwater robotic arms, hydraulic cutters, and other working tools. The underwater environment is harsh and dangerous, and human diving depth is limited. Underwater robots have become an important tool for ocean development, and in such environments, ordinary cables are no longer suitable for operation, hence the emergence of underwater robot cables (special cables).

Sohu Cable (Shanghai) Co., Ltd. specializes in designing and customizing wires and cables for mechanical equipment used for extension/retraction or towing in deep water. Various specifications of underwater robot cables can be customized according to customer requirements, such as signal transmission, power supply, and equipment control systems.

Underwater Cable Structure: Conductor Core: multiple strands of fine twisted ultra-fine oxygen-free copper wire / anti-corrosion tinned copper wire Conductor Structure: anti-twist layered structure; group-type gap filling; twisted pair structure and then layered bundling Insulation: PVC made from waterproof composite materials / corrosion-resistant Teflon plastic Color: black with white numbering or color-coded cores Tensile Structure: polyester yarn / high-strength tensile Kevlar ballistic wire / finely twisted steel wire Wrapping Material: to make the cable rounder and firmer, can add raw tape (PTFE) or high-quality non-woven fabric (more cost-effective) Shielding: aluminum foil shield / copper mesh braid / tinned copper mesh braid Inner Sheath: modified low-viscosity high-strength extrusion inner sheath, customizable (optional depending on environmental requirements) Outer Sheath: seawater-resistant special material (waterproof, acid and alkali resistant, radiation-resistant, corrosion-resistant, antimicrobial) ---

Application scenarios

Suoyou Cable (Shanghai) Co., Ltd. specializes in designing and customizing wires and cables for mechanical equipment used in deep water for telescoping and pulling. We can customize various specifications of underwater robot cables according to customer requirements, such as signal transmission, power supply, and equipment control systems. Underwater operation robot cables Seawater protection cables Usage characteristics Underwater operation robot cables Seawater protection cables Use characteristics Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, are expensive, but have high levels of confidentiality. Submarine power cables are mainly used for underwater transmission of high-power electrical energy, serving the same function as underground power cables, except for different application scenarios and laying methods. Because submarine cable engineering is recognized worldwide as a complex and challenging large-scale project, from environmental detection and marine physical surveys to cable design, manufacturing, and installation, complex technologies are required. Therefore, there are only a few manufacturers of submarine cables, mainly Norway, Denmark, Japan, Canada, the United States, the United Kingdom, France, Italy, and others, which provide laying technology in addition to manufacturing.

Frequently Asked Questions

How to connect seawater protection network cables for waterproofing?

It is necessary to use waterproof connectors and sealing processes to prevent moisture from seeping along the cable core, which could affect the signal and lifespan.

What kind of network cable is used for underwater surveillance?

Prefer network cables with overall braided shielding for better resistance to interference, and for long-distance transmission, it is recommended to check the attenuation margin.
