Marine Engineering Maintenance of Polyurethane Cables

Key Technical Data

In chemical, machine tool processing, and other scenarios, cutting fluids, oil stains, and acidic or alkaline media continuously corrode cable sheaths, causing general PVC/rubber materials to age and crack quickly, significantly shortening their service life. To address this issue, Shanghai Suoqi has optimized its polyurethane cables both in materials and processes: the conductors are multi-stranded, finely twisted, oxygen-free bare copper wires; the insulation is made of special elastomer materials; the outer sheath is imported polyurethane PUR/TPU, which is oil-resistant, acid and alkali-resistant, UV-resistant, and aging-resistant. In actual applications, the products have been recognized by customers in the marine, underwater, and mechanical fields for their wear resistance, tensile strength, and polyurethane performance. Customization according to drawings and direct shipment from stock are supported. For details, please contact 13311756197.

Product Features

High flexibility and bending resistance: The conductor uses multi-strand ultra-fine finely twisted oxygen-free copper wire, compliant with VDE 0295 Class 6 standards, combined with a highly elastic TPE insulation layer to give the cable outstanding flexibility. Tested to withstand over 10 million bending cycles, with a minimum bending radius of only 6D (D is the cable outer diameter), suitable for complex conditions such as frequent steering of underwater robots and reciprocating motion of the drag chain system.

Efficient and stable transmission The conductor is designed with low resistance, ensuring efficient power transmission with low energy loss. For signal transmission, shielding layers can be installed as needed, such as tin-plated copper wire braided shielding mesh, with a shielding coverage rate of ≥90%, effectively resisting electromagnetic interference and ensuring stable transmission of control and data signals for underwater equipment.

3. Application Scenarios Marine Aquaculture: Used for power supply and signal transmission of underwater aerators, feeders, and water quality monitoring equipment, resistant to corrosion from seawater and aquaculture chemicals, and adapted to frequent movement and bending operation conditions in water.

Underwater Detection: Provides power and control signals for underwater robots (ROVs), underwater cameras, sonar detectors, and other equipment, meeting their flexible operational needs in complex underwater environments and ensuring stable data transmission.

Marine energy: connects internal equipment of wind turbine towers, submarine cables, and converters in offshore wind farms to stably transmit large amounts of electricity; Used as a key connecting cable in tidal and wave energy power generation equipment, adapting to harsh marine conditions.

Frequently Asked Questions

How to choose between polyurethane cables and PVC cables?

For indoor, dry, low-cost scenarios, PVC can be selected; for oily, outdoor, frequently moving, or long-life requirements, PUR is the priority.

What makes polyurethane (PUR) cables so good?

PUR jackets are wear-resistant, oil-resistant, hydrolysis-resistant, and antimicrobial, with comprehensive mechanical properties superior to PVC, making them suitable for harsh conditions such as oil, humidity, and outdoor environments.
