In water-related environments such as coastal ports, aquaculture, and shallow sea operations, ordinary cables are corroded by seawater salt ions, with insulation layers rapidly aging and conductor oxidation and corrosion, making safety hazards prominent. Shanghai Suoqi Seawater Protection Cable is designed for underwater sensor power supply conditions in diving equipment, featuring salt spray and hydrolysis resistance, a core stranded with tin-plated copper braided shielding, and a special seawater-resistant PUR composite sheath resistant to salt ion penetration corrosion, suitable for high-humidity offshore 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, with multiple core counts and specifications customized on demand, ample stock, nationwide shipping, and a consultation hotline 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.
