500MΩ
300/500V

In coastal ports, aquaculture, shallow-sea operations, and other water-related environments, ordinary cables are corroded by seawater salt ions, causing the insulation layer to age rapidly and the conductors to oxidize and rust, posing significant safety hazards. Shanghai Suoqi seawater-resistant cables are designed for the underwater lighting power supply conditions of underwater equipment. They adopt a double-shielding anti-interference structure, with multi-strand conductors made of oxygen-free copper wire, special waterproof elastomer insulation, a salt spray-resistant polyurethane (PUR) outer sheath, double-layer sealing with waterproof gel filling, and an IP67 waterproof rating. The cables feature high flexibility and properties of polyurethane (PUR) and are widely used in chemical, underwater, and robotic fields. Shanghai Suoqi Cables are sold directly from the source factory, customizable with various core counts and specifications, with ample stock for nationwide delivery. Inquiry 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.

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.

What are the key points for selecting cables for offshore platforms?

Clarify water depth, whether it moves, temperature range, and mechanical stress, and prioritize salt spray-resistant PUR sheaths with tensile reinforcement structures.
