Shanghai Suoqi Cable Co., Ltd. is deeply engaged in the field of special flexible cables. The following provides a professional interpretation of seawater-resistant cables from three dimensions: material structure, performance advantages, and application scenarios.
Product original reference: Special cable with seawater-resistant, corrosion-resistant weak acid and alkali sheath
1. Materials and Structural Parameters
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
Tensile Structure: Polyester Yarn Fiber / High-Strength Tensile Kevlar Bulletproof Fiber / Precision Stranded Steel Wire
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)
2. Performance Technical Indicators
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.
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.
Minimum bending radius: fixed installation 3×D (cable outer diameter); Mobile use 5×D (cable outer diameter)
Minimum bending radius: Fixed installation 6×D (cable outer diameter); Mobile use 12×D (cable outer diameter)
Minimum bending radius: Fixed installation 6×D (cable outer diameter); Mobile use 10×D (cable outer diameter)
1. High flexibility - high toughness - bend-resistant - twist-resistant (prevents internal core breakage of the cable under frequent bending)
5. Seawater resistance – Extremely strong weather resistance, effective underwater operation (cold resistance, oxidation resistance, antimicrobial protection, radiation resistance, corrosion resistance, ozone resistance, acid and alkali salt spray corrosion resistance)
3. Application Scenarios
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.
Underwater cables can be divided into: ① video cables; ② signal cables; ③ control cables; ④ power cables; ⑤ composite 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.
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.
