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.
1. Materials and Structural Parameters
Seawater Protection Cable Product Overview: Product Application Custom-produced composite seawater protection cable, integrating power core, control core, signal core, and video cable design into one cable. Applied in underwater equipment, it meets various functional needs, effectively reduces cable weight and outer diameter, and facilitates cable installation and laying. Zero-buoyancy floating structure composite underwater cables can also be customized. Inquiries are welcome.
Product Structure Conductor: Ultra-fine oxygen-free bare copper wire/tinned copper wire, multi-strand precision twisted and bundled; Insulation: Various materials such as special mixed elastomer/automotive materials/TPE/TPV; Shielding: Aluminum foil Mylar; high-density braided shield layer of tinned copper wire/bare copper wire, designed as single-layer or dual-layer separated and total shielding structure; Jacket: Polyurethane material specially designed for seawater resistance. Product Features 1. Functional: This type of composite seawater-resistant cable integrates multiple functional cores, meeting different functional requirements when used in underwater equipment, such as power transmission, signal control, data signal transmission and feedback, video signal transmission, etc.; 2. Electromagnetic Interference Resistance: High-density braided shielding of tinned copper wire/bare copper wire/aluminum foil Mylar, designed as single-layer or dual-layer separated and total shielding structure, effectively countering electromagnetic interference, ensuring stable signal transmission and feedback, and effectively preventing mutual interference between cores; 3. Flexibility: Optimized cable material selection and structural design make the cable flexible and bend-resistant, suitable for mobile use or fixed installation in underwater environments; 4. The outer jacket made of polyurethane material specially designed for seawater resistance gives the cable excellent waterproof, wear-resistant, oil-resistant, water-resistant, and corrosion-resistant properties, making it widely applicable for installation and use in freshwater or seawater environments.
Product Electrical Parameters Rated Voltage: 0.6/1KV and below voltage range can be customized; Temperature Range: -40~90℃; Bending Radius: 7.5~8*D (for mobile use);
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.
