Anti-Seawater Cable for Underwater Robots - Seawater-Corrosion-Resistant Cable

SOQO Anti-Seawater Cable — The Power Transmission Expert for Marine Environments

With the booming development of ocean development and construction, reliable power and signal transmission is indispensable—whether for the stable operation of offshore oil drilling platforms, the precise exploration missions of underwater robots, or the efficient operation of fishery equipment. Shanghai SOQO Electric Wire & Cable Co., Ltd. has been deeply engaged in the cable industry and has carefully crafted its anti-seawater cable, which, with outstanding performance, has become a solid backing for all kinds of marine engineering and underwater operations.

I. Core Product Advantages

(I) Exceptional Corrosion Resistance

Special Sheath Material

Polyurethane (PUR) is used as the main outer-sheath material. It offers outstanding resistance to seawater corrosion and can effectively withstand high-salinity seawater, microorganisms, and various chemical substances, resisting aging and cracking even after long-term use and ensuring the cable's service life in harsh marine environments.

Internal Conductor Protection

The internal conductors are made of high-purity oxygen-free copper with special treatment to enhance corrosion resistance, maintaining excellent conductivity in seawater environments and reducing corrosion-induced increases in resistance and power transmission losses.

(II) High Flexibility and Bend Resistance

Fine-Stranded Conductor Structure

The conductors are carefully stranded from multiple fine copper wires, giving the cable outstanding softness. In underwater scenarios with frequent bending and twisting, it easily adapts to complex movements without conductor breakage, ensuring continuous power and signal transmission.

Optimized Cabling Process

Through precise control of the stranding lay length and special structural design, the cable's bend resistance is greatly improved, making it suitable for high-frequency bending environments such as underwater robots moving and turning frequently in narrow spaces, effectively extending the cable's actual service life.

(III) Outstanding Waterproof and Sealing Performance

Premium Waterproof Insulation Material

The insulation layer uses special water- and oil-resistant insulating material with good electrical insulation. It also prevents moisture from penetrating to the conductor even during seawater immersion, ensuring safe, stable cable operation.

Rigorous Sealing Process

Strict control over sealing is applied at every production step, ensuring the cable's overall waterproof rating meets high standards. Some products achieve no water seepage at depths of hundreds of meters underwater, meeting the needs of different marine operation depths.

(IV) Strong Tensile Capability

Built-in Tensile Reinforcement Elements

Tensile reinforcement elements such as Kevlar fibers or galvanized anti-tensile steel wire ropes are added inside the cable. These high-strength materials effectively share the tension the cable experiences in use, greatly enhancing overall tensile strength so it can withstand significant external pulling forces without damage.

Rational Structural Design

Through a scientific and rational structural layout, all component materials work together under tension to distribute pulling forces evenly, further improving tensile performance—ideal for engineering scenarios with extremely high tensile requirements such as offshore wind power and submarine cable laying.

II. Rich Application Scenarios

(I) Marine Engineering

Offshore Oil Drilling Platforms

Provides stable power transmission for various platform equipment, such as drilling equipment, oil extraction equipment, and living facilities, ensuring normal platform operation in complex marine environments. It also serves as the signal link between the platform and underwater equipment, ensuring accurate and timely data transmission.

Offshore Wind Farms

Connects offshore wind turbines to onshore substations for efficient power transmission. Facing sea breeze, waves, and seawater corrosion over the long term, SOQO anti-seawater cables guarantee stable power generation and reduce maintenance costs.

(II) Underwater Robots and Unmanned Underwater Vehicles

As the power and signal transmission cable for underwater robots (ROV/UUV), SOQO anti-seawater cable meets the demands of flexible movement and operation over complex underwater terrain. Whether for deep-sea exploration, underwater salvage, or submarine pipeline inspection, it ensures the robot receives stable power supply and transmits collected data accurately back to the control center.

(III) Fishery Equipment and Aquaculture

Underwater Camera and Monitoring Equipment

Provides power and signal transmission for underwater cameras, water-quality monitoring, fish detection, and other aquaculture equipment, helping farmers track the farming environment and fish growth in real time for scientific aquaculture.

Smart Aquaculture Equipment

Connects various smart aquaculture devices such as feeders and aerators for remote control and automated management, improving farming efficiency and reducing labor intensity.

(IV) Marine Scientific Research

Marine Biology Research

Connects marine biology observation equipment such as underwater cameras and sensors, helping researchers gain deeper insight into marine life habits and distribution patterns, providing data support for marine biodiversity conservation and research.

Marine Physics and Chemistry Research

Delivers stable power and signal transmission for marine physics and chemistry detection equipment, enabling precise monitoring and analysis of environmental parameters such as temperature, salinity, and pH, and advancing marine science research.

III. Product Specifications and Customization

(I) Standard Product Specifications

Shanghai SOQO offers anti-seawater cables in various specifications with conductor cross-sections from 4 to 300 mm², meeting the power transmission needs of different equipment; rated voltages include 0.6/1 kV and other levels to fit the electrical requirements of various marine scenarios; a rich range of cores from single-core to multi-core can be flexibly chosen per actual needs.

(II) Customized Solutions

Understanding the uniqueness of different marine engineering and underwater operations, SOQO's professional technical team provides comprehensive customization based on specific customer needs—whether special cable lengths, special waterproof ratings, or integrated functions such as optical fiber or air hoses—to tailor the most suitable anti-seawater cable solution.

IV. Professional Quality Assurance

(I) Advanced Production Processes

Strict Raw Material Screening

Quality is controlled at the source. Every batch of raw materials, including conductor copper, insulation materials, and sheath materials, undergoes strict quality inspection to ensure compliance with standards and design requirements, laying a solid foundation for producing quality anti-seawater cables.

Precision Production Equipment and Processes

Advanced domestic and international cable production equipment and mature, refined processes are used—precision conductor stranding, accurate insulation extrusion, and efficient sheath compounding—monitoring every step strictly to ensure each performance indicator meets or exceeds industry standards.

(II) Comprehensive Quality Inspection System

Multi-Stage Quality Inspection

A complete quality inspection system covers incoming raw-material inspection, in-process patrol inspection, and full finished-product inspection. During production, key indicators such as conductor resistance, insulation, waterproofing, and tensile strength are monitored in real time, identifying and resolving potential quality issues promptly.

Simulated Marine Environment Testing

To ensure reliability in real marine environments, a dedicated simulated marine environment laboratory performs salt-spray tests, hydraulic pressure tests, and high/low temperature cycling tests on finished cables, simulating the extreme conditions cables may face at sea. Only products passing all rigorous tests are approved for delivery.
