1. Materials and Structural Parameters
Shanghai Suoqi Marine-Resistant Cables — Experts in Power Transmission in Marine Environments In the current booming development of marine exploration and construction, whether it is the stable operation of offshore oil drilling platforms, the precise detection tasks of underwater robots, or the efficient operation of fishing equipment, all rely on reliable power and signal transmission. Shanghai Suoqi Electric Wire & Cable Co., Ltd. has been deeply engaged in the cable industry, and its carefully crafted marine-resistant cables, with outstanding performance, have become a solid support for various marine engineering and underwater operations.
1. Core Product Advantages (1) Superior Corrosion Resistance Special Sheath Material: Using polyurethane (PUR) as the main material for the outer sheath, this material has extremely excellent resistance to seawater corrosion and can effectively resist the erosion of high-concentration salts, microorganisms, and various chemicals in seawater. Even with long-term use, it is not prone to aging or cracking, ensuring the cable's service life in harsh marine environments.
Internal Conductor Protection: The internal conductor is made of high-purity oxygen-free copper and is treated with a special process to enhance its corrosion resistance. It can maintain excellent electrical conductivity even in a seawater environment, reducing increases in resistance and power transmission losses caused by corrosion.
(2) High flexibility and bending resistance: Multi-strand finely stranded conductor structure: The conductor is carefully twisted from multiple strands of fine copper wire, giving the cable excellent flexibility. This allows it to easily adapt to various complex operations in frequently bent and twisted underwater operations, making it less likely to break and ensuring continuous power and signal transmission.
Optimized cabling process: By precisely controlling the cabling pitch and matching it with a special structural design, the bending resistance of the cable is greatly improved. It is suitable for high-frequency bending work environments, such as underwater robots moving and turning frequently in narrow spaces, effectively extending the actual service life of the cable.
(3) Excellent Waterproofing and Sealing Performance High-Quality Waterproof Insulation Material: The insulation layer uses special water- and oil-resistant insulation material, which not only has good electrical insulation performance but also prevents moisture from penetrating the conductor in a seawater immersion environment, ensuring the safe and stable operation of the cable.
Strict sealing process: Starting from each step of the production process, the sealing performance of the cable is strictly controlled to ensure that the overall waterproof level of the cable reaches a high standard. Some products can achieve zero water ingress at depths of several hundred meters underwater, meeting the requirements of different ocean operation depths.
(4) Strong Tensile Strength Built-in Tensile Reinforcement Elements: Additional reinforcement elements such as Kevlar tensile fibers or galvanized steel wire ropes are added inside the cable. These high-strength materials can effectively share the tension the cable experiences during use, greatly enhancing the overall tensile strength of the cable, allowing it to withstand greater external pulling forces, and preventing cable damage due to excessive tension.
Rational structural design: Through a scientific and reasonable structural layout, the cable works synergistically among various materials when subjected to tensile forces, evenly dispersing the tension and further improving the cable's tensile performance. This is suitable for engineering scenarios with extremely high tension requirements, such as offshore wind power and submarine optical cable laying.
II. Diverse Application Scenarios (1) Marine Engineering Field Offshore oil drilling platforms: Provide stable power transmission for various equipment on the platform, such as drilling equipment, oil extraction equipment, and living facilities, to ensure the normal operation of the platform in complex marine environments. At the same time, they are used for signal connections between the platform and underwater equipment, ensuring accurate and timely data transmission.
2. Performance Technical Indicators
Rated voltage 0.6/1 kV; longitudinal watertight performance can reach a water depth of 300 m; applicable temperature range -20℃ to 80℃; salt spray resistance test not less than 1000 h, excellent hydrolysis resistance, can be used stably in marine environments for a long time.
3. Application Scenarios
Seawater protection cables are widely used in industrial automation, lifting and transportation, ports and docks, and other fields.
