Seawater-Resistant Cable — Shipboard Platform Seawater-Resistant Cable Corrosion Resistance Requirements

Key Technical Data

40℃
80℃

In water-related environments such as coastal ports, aquaculture, and shallow sea operations, ordinary cables are corroded by seawater salt ions, with rapid aging of insulation layers and conductor oxidation and corrosion, making safety hazards prominent. Shanghai Suoqi Seawater Protection Cable is specially designed for these conditions, featuring a stranded core with tin-plated copper braided shielding, and a sheath made of specially made seawater-resistant PUR composite material, resistant to salt ion penetration corrosion, suitable for underwater nearshore high-humidity salt spray environments. The cable features high flexibility, polyurethane, and PUR, and is widely used in chemical, underwater, robotics, and other fields. Shanghai Suoqi Cable is sold directly from the source factory, customizing multiple cores and specifications on demand, with ample stock and nationwide shipping. Hotline 13311756197 consultation.

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 durability, safe and environmentally friendly. Operating temperature range reaches **-40℃~80℃**, and it can operate normally in both cold sea areas and high-temperature working environments. 3. Application Scenarios Marine aquaculture and monitoring: Used for power supply and signal transmission of underwater aerators and water quality monitoring equipment, resistant to corrosion from seawater and aquaculture chemicals, and adaptable to equipment mobility requirements.

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.

Underwater detection robot: Provides power and control signal transmission for underwater robots, with a highly flexible design that matches the robot's agile movement characteristics.

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.

Do seawater-resistant cables need to undergo salt spray testing?

Required. High-quality products must withstand salt spray tests for ≥1000 hours to verify the jacket's resistance to marine corrosion and microbial erosion.
