Features of seawater-resistant cables
In important situations such as between distant islands and across-sea facilities. The laying distance of submarine power cables is much shorter compared to communication cables, mainly used between mainland and islands, across rivers or harbors, connecting offshore drilling platforms from the mainland, or interconnecting drilling platforms. In general, using submarine cables to transmit electricity is undoubtedly more expensive than overhead cables of the same length, but it is often more economical than relying on small, isolated power plants for regional power generation, and it offers more advantages in offshore areas. In regions with many islands and rivers, this type of cable is widely used.
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 for mobile or fixed installation, underwater environment (freshwater or seawater), depth, etc.
Underwater cables can be divided into: ① video cables; ② signal cables; ③ control cables; ④ power cables; ⑤ composite cables
Applications of underwater cables:
Underwater ROV Unmanned Remote-Controlled Submersible - Applications such as 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. In such an environment, ordinary cables are no longer suitable for operation, thus underwater robot cables (special cables) were born.

Underwater work robot cables: Seawater protection cables
Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services; they are expensive but offer a high level of confidentiality. Submarine power cables are mainly used for underwater transmission of high-power electricity, and their function is equivalent to that of underground power cables, except that the application scenarios and laying methods are different. Since submarine cable projects are recognized by all countries as large-scale projects that are complex and difficult, from environmental detection, marine physical survey, to cable design, manufacturing, and installation, complex technologies are applied. Therefore, there are only a few manufacturers of submarine cables, mainly in countries such as Norway, Denmark, Japan, Canada, the United States, the United Kingdom, France, and Italy. In addition to manufacturing, these countries also provide laying technology.
Underwater cable structure:
Conductor core: multiple strands of finely twisted fine-grade oxygen-free copper wire / anti-corrosion tinned copper wire
Conductor structure: anti-twist structure layering; grouped gap filling; layered bundling after twisted pair structure
Insulation: Made of waterproof mixed materials PVC / corrosion-resistant Teflon plastic
Color: black with white numbers or colored wire core with color coding
Tensile Structure: Polyester Yarn Fiber / High-Strength Tensile Kevlar Bulletproof Fiber / Precision Stranded Steel Wire
Wrapping materials: To make the wire more round and firm, you can add raw tape (PTFE) or high-quality non-woven fabric (cost-effective).
Shielding: Aluminum Foil Shielding / Copper Mesh Braiding / Tinned Copper Mesh Braiding Shielding
Inner Sheath: Modified low-viscosity high-strength extrusion inner sheath, customizable (optional depending on environmental requirements)
Outer sheath: Special material for seawater protection (waterproof, resistant to acids and alkalis, radiation-resistant, corrosion-resistant, antimicrobial)
