The key to selecting seawater-resistant cables is based on operating conditions. Shanghai Suoqi seawater-resistant cables use multi-stranded tinned copper conductors, special waterproof elastomer insulation, and a salt-spray-resistant polyurethane (PUR) outer sheath, with double-layer sealing and waterproof adhesive filling. They have an IP67 waterproof rating and feature high flexibility, polyurethane, and PUR among other core advantages, making them widely adaptable to chemical, underwater, robotic, and other 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

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.

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.
