The company has a professional team of experienced technical engineers, leveraging advanced R&D technology, strict quality control systems, and stable raw material supply channels, dedicated to providing global customers with high-quality, high-performance, and customized wire and cable solutions, establishing a strong reputation and credibility in the industry.
2. Product Structure Analysis
(1) Conductors
Made by twisting high-purity oxygen-free copper strands, this conductor not only has excellent conductivity and effectively reduces losses during power transmission, but also has good flexibility, adapting to various complex bending requirements during cable installation and use. The multi-strand strand structure enhances the conductor's tensile strength, ensuring stable power transmission even under strong external pulls.
(2) Insulation layer
Using specially formulated polymer insulating materials, it has excellent electrical insulation properties, can withstand high voltage, effectively prevent current leakage, and ensure electrical safety. At the same time, this insulating material also has a certain resistance to seawater, salt spray, etc., preventing a decrease in insulation performance caused by seawater corrosion, thereby extending the service life of the cable.
(3) Shielding layer (for certain models)
For some application scenarios sensitive to electromagnetic interference, some cables are equipped with shielding layers. Using shielding methods such as aluminum foil or tin-plated copper braiding can effectively block external electromagnetic interference, ensuring the accuracy and stability of internal signal transmission, suitable for equipment connections with high signal transmission quality requirements.
(4) Sheath
The outer sheath is made of polyurethane polyether material, a high-performance material specially designed for seawater resistance. It has extremely strong corrosion resistance to seawater and can be soaked in seawater for a long time without being corroded or damaged; at the same time, it also has good wear resistance, oil resistance, and weather resistance. Under the complex environmental conditions of the ocean, such as friction from sand and stones, contamination by oil, or extreme temperature changes, it can still maintain good physical properties and protective functions, providing reliable protection for the internal structure of the cable.
3. Product Performance Advantages
(1) Outstanding resistance to seawater corrosion
Through special process treatment and material selection, this cable can operate stably in seawater for a long time. Through experimental tests such as simulated seawater immersion and salt spray corrosion, over a testing period of several years, various performance indicators of the cable, such as insulation resistance and conductor resistance, have remained within a stable range, with no significant performance degradation or structural damage, effectively ensuring normal power supply and signal transmission for equipment in marine environments.
(2) High flexibility and bending fatigue resistance
Cables have excellent flexibility and a small bending radius, easily adapting to various complex installation environments and equipment movement trajectories. After extensive bending fatigue tests, even after millions of bendings, the conductor, insulation, and sheath remain intact, with no issues such as core breakage or insulation damage. They are suitable for marine equipment that requires frequent movement and bending, such as offshore cranes and underwater robots.
(3) Excellent electrical performance
The combination of the conductor's excellent conductivity and the high insulation performance of the insulation layer enables the cable to maintain low loss and high stability during power transmission. At the same time, the effective function of the shielding layer can resist various electromagnetic interferences, ensuring the cable's accuracy during signal transmission. Whether used for power transmission or data communication, it meets the high requirements of the equipment.
(4) Extensive environmental adaptability
In addition to resistance to seawater corrosion, this cable can also adapt to other harsh conditions in marine environments. Within the temperature range of -40°C~80°C, the cable's flexibility and electrical performance are not compromised, allowing reliable operation whether in cold polar seas or hot tropical ocean regions. Additionally, it has certain resistance to oil pollution, chemicals, and more, making it suitable for various complex marine operation scenarios.
IV. Application Scenarios (1) Marine Engineering Construction
In the construction of offshore oil platforms, cross-sea bridges, and underwater tunnels, large amounts of power supply and signal transmission cables are required. Shanghai Suo Qi's seawater protection cables, with their excellent anti-corrosion performance and stable electrical performance, can meet the demands of these projects in harsh marine environments, ensuring smooth construction and normal equipment operation.
(2) Marine Fisheries
In fishing vessels, aquaculture cages, and other fishery equipment, cables need to be exposed to seawater environments for extended periods. The cable's high flexibility and resistance to bending fatigue allow it to adapt to the rocking of fishing boats and frequent equipment movements. At the same time, its excellent seawater corrosion resistance extends cable service life, reduces maintenance costs, and ensures stable fishery production.
(3) Underwater Detection and Monitoring
For underwater robots, marine monitoring equipment, and similar devices, reliable cables are needed for power transmission and data communication. Shanghai Suo Qi's seawater protection cables can effectively resist seawater erosion and external electromagnetic interference, ensuring stable connections between underwater equipment and surface control centers, and providing strong support for marine scientific research and resource exploration.
(4) Port facilities
In port cranes, loading and unloading equipment, and other facilities, cables need to operate in humid, saline air environments and may come into contact with seawater. The seawater resistance and wear resistance of these cables enable them to adapt to the complex working environment of the port, ensure the normal operation of the equipment, and improve the operational efficiency of the port.
5. Customization Services
Shanghai Suoqi is well aware that different customers have different cable needs in different application scenarios, and therefore provides comprehensive customization services:
(1) Custom Number of Cores
The number of cores in the cable can be customized according to actual needs, ranging from single-core to multi-core (such as 2 - 60 cores), to meet the power transmission and signal control requirements of different devices.
(2) Cross-sectional area customization
The cable conductor cross-sectional area can be selected and customized between 0.14 and 25mm² to ensure the cable can carry the corresponding current and meet the power requirements of devices with different power levels.
(3) Customization of shielding types
Depending on the electromagnetic interference conditions in the operating environment, customers can choose different shielding structures such as unshielded, single-layer shielding (such as aluminum foil shielding), or double-layer shielding (aluminum foil, tin-plated copper braided shielding), to enhance the cable's anti-interference performance.
(4) Customization of Special Functions
For certain special application requirements, such as the need for waterproof sealing, high-temperature resistance, and radiation resistance, the company's R&D team can carry out targeted design and production, providing customers with personalized cable solutions.
