In coastal ports, aquaculture, shallow sea operations, and other water-related environments, ordinary cables are corroded by seawater salt ions, causing rapid aging of insulation layers and conductor oxidation and corrosion, with prominent safety hazards. To address this pain point, Shanghai cable-resistant cables have been optimized in both materials and processes: the conductor is stranded with oxygen-free copper wire, special waterproof elastomer for insulation, the outer sheath is salt-spray-resistant polyurethane PUR, double-layer sealing with waterproof adhesive, and has an IP67 waterproof rating. In practical applications, the product has been recognized by customers in the underwater, mechanical, and robotics sectors for its tensile strength, corrosion resistance, and shielding performance. Supports customization according to drawings and direct shipment from stock. Please inquire for 13311756197 details.

Product Features

Suoqi Cable (Shanghai) Co., Ltd. specializes in designing and customizing electrical wires and cables for mechanical equipment used for extension/retraction and towing in deep water. Various specifications of underwater robot cables can be customized according to customer requirements, such as for signal transmission, power supply, and equipment control systems.

When ordering, please specify the usage environment: such as tensile load, whether it is used for mobile or fixed installation, underwater environment (freshwater or seawater) depth, etc. Underwater cables can be divided into: ① video cable; ② signal cable; ③ control cable; ④ power cable; ⑤ composite cable. Applications of underwater cables: Underwater ROV unmanned remotely operated vehicles - underwater filming, underwater salvage, underwater construction, etc. Equipped with underwater robotic arms, hydraulic cutters, and other working tools. The underwater environment is harsh and dangerous, and human diving depth is limited. Underwater robots have become an important tool for ocean development, and in such environments, ordinary cables are no longer suitable for operation, hence the emergence of underwater robot cables (special cables).

Application scenarios

Suoyou Cable (Shanghai) Co., Ltd. specializes in designing and customizing wires and cables for mechanical equipment used in deep water for telescoping and pulling. We can customize various specifications of underwater robot cables according to customer requirements, such as signal transmission, power supply, and equipment control systems. Underwater operation robot cables Seawater protection cables Usage characteristics Underwater operation robot cables Seawater protection cables Use characteristics Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, are expensive, but have high levels of confidentiality. Submarine power cables are mainly used for underwater transmission of high-power electrical energy, serving the same function as underground power cables, except for different application scenarios and laying methods. Because submarine cable engineering is recognized worldwide as a complex and challenging large-scale project, from environmental detection and marine physical surveys to cable design, manufacturing, and installation, complex technologies are required. Therefore, there are only a few manufacturers of submarine cables, mainly Norway, Denmark, Japan, Canada, the United States, the United Kingdom, France, Italy, and others, which provide laying technology in addition to manufacturing.

Technical indicators

Underwater cable structure

Conductor core: multi-strand fine-stranded oxygen-free copper wire / anti-corrosion tinned copper wire; Conductor structure: anti-twist layered structure; Grouped gap filling; Twisted pair structure with layered bundling cable features: 1. High flexibility - high toughness - bending resistance - twist resistance (prevents internal cable breakage during frequent bending) 2. Wear resistance - notch resistance - high compression strength (outer sheath is stable against external force damage) 3. Electronic interference resistance - integrated braiding high shielding density and special structural design effectively resist external and internal interference, ensuring signal transmission stability 4. Tensile strength - underwater impact resistance - high-strength Kevlar tensile fiber acts as the cable's tensile center or tensile braiding, forming the cable into a round shape that evenly bears tensile forces, ensuring long-term effective operation without cracking. (When working underwater, cables can withstand the tensile forces of connected equipment or heavy objects, with a maximum breaking force of over 1 ton. In special cases, tensile steel wire can be added.) 5. Seawater Resistance—Extremely Strong Weather Resistance—Effective for underwater operation (cold resistance, oxidation resistance, antimicrobial resistance, radiation protection, corrosion resistance, ozone resistance, acid and alkali salt spray corrosion resistance). 6. Sheath—Made with imported TPU special materials mixed with special materials—Effectively designed for seawater and other harsh environments.

Frequently Asked Questions

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.

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.
