The key to selecting seawater-resistant cables is to consider the operating conditions. Shanghai Suoqi's seawater-resistant cables use twisted pair tinned copper braid shielding and a special PUR composite sheath resistant to seawater, preventing corrosion from salt ions. They are suitable for underwater, nearshore, high humidity, and salt spray environments, offering core advantages such as tensile strength, corrosion resistance, and shielding. They can be widely used in underwater, mechanical, and robotic applications. Direct sales from the source manufacturer with stable delivery times.

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

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.
