The key to selecting seawater-resistant cables is to consider the operating conditions. Shanghai Suoqi's seawater-resistant cables use twisted pair tinned copper braid shielding for the core wires, with a specially formulated seawater-resistant PUR composite sheath that resists corrosion from salt ions. They are suitable for underwater, near-shore, high-humidity, and salt-spray environments. These cables feature high flexibility and core advantages such as polyurethane (PUR), making them widely adaptable to chemical, underwater, and robotics applications.

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 deep water pressure can seawater-resistant cables withstand?

The vertical watertight type can reach a water depth of 300m, with the specific model selected according to the laying depth, and the joint sealing process confirmed.

Why do seawater protection cables use tin-plated copper conductors?

The tin plating layer blocks corrosion of copper caused by seawater chloride ions, and together with the PUR sheath and composite shielding, it ensures long-term underwater electrical stability.
