Marine monitoring, underwater aquaculture, and similar scenarios have high requirements for data transmission. Conventional network cables cannot withstand seawater corrosion and humid environments, and severe signal attenuation can lead to communication interruptions. Shanghai Suoqi's seawater-resistant network cables are specifically designed for such conditions, featuring high-purity oxygen-free copper conductors, twisted pairs with aluminum foil shielding, tinned copper overall shielding, and seawater-resistant polyurethane (PUR) outer jackets, ensuring stable underwater signal transmission. The cables are highly flexible and have properties like polyurethane (PUR), making them widely used in fields such as chemical industry, underwater operations, and robotics. Shanghai Suoqi Cable offers factory-direct sales, customizing multi-core and various specifications on demand, with ample stock available for nationwide shipping. For inquiries, call 13311756197.

Product Features

Highly flexible design, worry-free in mobile scenarios. Internally, it uses multi-stranded, finely twisted oxygen-free copper conductors, combined with highly elastic TPE insulation material and a Kevlar tensile fiber braided layer, giving the cable excellent flexibility. Tests show it can withstand over 8 million bending cycles, with a minimum bending radius of 6D (D being the cable's outer diameter). In drag chain systems, underwater robots, or other frequent movement or bending conditions, it maintains continuous conductivity without breaking, meeting the demands of high-dynamic applications.

Wide temperature range, durable, safe and environmentally friendly. Operating temperature range reaches **-40°C~90°C**, suitable for normal use in cold seas and high-temperature working environments. No halogen or heavy metal additives. Insulation resistance ≥ 500MΩ/km, voltage resistance rating up to 300/500V, flame retardant rating compliant with IEC 60332-1 standard, safe and reliable.

3. Application Scenarios Marine Aquaculture and Monitoring: Used for power supply and signal transmission of underwater aerators and water quality monitoring equipment, resistant to seawater and aquaculture agent corrosion, and adapted to equipment mobility needs.

Coastal Chemical and Environmental Protection Engineering: In the wiring of equipment such as pump bodies and agitators for handling weakly acidic and alkaline wastewater, resist corrosion while meeting the high flexibility requirements for frequent start-stop of the equipment.

Port loading and unloading and ship equipment: Compatible with port crane drag chain systems and ship deck mobile equipment connections, handling sea breeze salt spray and engine room oil contamination environments.

Frequently Asked Questions

How to connect seawater protection network cables for waterproofing?

It is necessary to use waterproof connectors and sealing processes to prevent moisture from seeping along the cable core, which could affect the signal and lifespan.

What is the difference between seawater protection cables and regular cables?

Ordinary cables are not resistant to salt spray or water immersion. Seawater-resistant cables use PUR sheaths and independent aluminum foil shielding, allowing long-term stable signal transmission underwater.
