Coaxial + Power + Communication Multi-core Special Cable for Underwater Robot Connectors

Special cable for underwater robot connectors, coaxial + power + communication multi-core watertight cable Shanghai Oukesen Wire & Cable Co., Ltd. focuses on the R&D and manufacturing of marine cables, and is committed to providing high-quality cable products that meet the connection needs of underwater robots. With the wide application of underwater robots in marine exploration, environmental monitoring, submarine repair and other fields, higher requirements have been put forward for the performance of connector-specific cables. This article will deeply analyze the advantages and characteristics of coaxial + power + communication multi-core watertight cable from the aspects of marine cable application scope, installation method, key precautions, product material and manufacturing process.

I. Application scope and demand characteristics of marine cables

Underwater robots usually undertake complex task environments. The cable not only needs to transmit power, but also must ensure stable signal transmission. The coaxial + power + communication multi-core watertight cable produced by Shanghai Oukesen is suitable for underwater robot connectors, and is widely used in:

• Marine oil exploration operations, used for real-time data transmission and equipment power supply.

• Submarine pipeline inspection, requiring the cable to have good dynamic flexibility and wear resistance.

• Continuous seabed operation of environmental monitoring equipment, the cable needs to have excellent corrosion resistance and waterproof performance.

• Deep-sea scientific research and application, the signal transmission of the cable must be anti-interference and distortion-free.

These application scenarios put forward extremely high requirements on the comprehensive performance of the cable, especially the integration of power, coaxial signal and communication functions, to ensure watertightness and mechanical strength.

II. Installation method and engineering practice

Correct installation method is the foundation to ensure the long-term stable operation of the cable. When installing the special cable for underwater robot connectors, it is recommended to follow the following steps:

1. Select cables of appropriate specifications and lengths to ensure that they meet the installation depth and rotation requirements, and avoid being too tight or too loose.

2. Protect the cable ends to ensure the waterproof sealing at the joints, and use watertight connectors and sealing rings.

3. The laying path should avoid sharp objects and friction points as much as possible. For nodes that are easy to bend, a bending protection sleeve can be installed.

4. After installation, conduct water leakage detection and signal integrity tests to ensure the overall performance of the connectors and cables.

5. Regularly check the appearance of the cable and connectors to prevent mechanical damage and seal failure.

During the installation process, special attention should be paid to the drag force under the action of water flow and the self-weight of the cable. In the deep-sea environment, appropriate tension adjustment and support measures are indispensable.

III. Precautions

• Avoid direct sunlight on the cable in high-temperature or chemical corrosion environments, and try to use coating protective layers or install protective pipes.

• When designing, the mutual interference between signal lines and power lines should be considered, and reasonable wiring should be carried out to improve communication stability.

• Prevent bending and extrusion during storage and transportation, and avoid internal conductor breakage or insulation layer damage of the cable.

• Watertight performance is of utmost importance. Any tiny damage may cause short circuit or failure of internal lines.

• During dynamic use, pay attention to the small bending radius of the cable to avoid performance deterioration caused by frequent bending.

Shanghai Oukesen has fully considered the above factors in product design, and has manufactured special cables that are both durable and stable.

IV. Introduction to product materials

Material is the foundation of ensuring performance. The multi-core watertight cables of Shanghai Oukesen strictly select high-quality raw materials:

• The conductor body is made of high-purity oxygen-free copper wire, ensuring low resistance and stable signal transmission.

• The coaxial part uses aluminum foil and braided copper mesh with excellent effects, which greatly reduces electromagnetic interference.

• The insulation layer is made of high-strength polyethylene (PE) or polyvinyl chloride (PVC), with excellent waterproof performance and aging resistance.

• The outer sheath is made of special rubber or polyurethane material, with the ability of UV resistance, seawater corrosion resistance and mechanical wear resistance.

• The internal filler uses waterproof filler or bentonite layer, improving the overall compression strength and watertight grade.

The scientific proportioning and strict testing of these materials ensure that the cable still performs well under harsh seabed conditions.

V. Advanced manufacturing process

The manufacturing process determines the stability and durability of the cable. Shanghai Oukesen uses a number of advanced technologies:

• Automatic extrusion molding equipment is used to ensure that the insulation layer and sheath are uniform and defect-free.

• The coaxial layer is multi-layer composite braided, improving anti-interference effect and mechanical flexibility.

• High-precision stranding process makes the multi-core cable structure compact and reduces signal crosstalk.

• Multiple watertight technologies, combined with double-layer sealing of epoxy resin and heat-shrinkable tubes, extend the service life.

• Strict quality control process, each cable undergoes voltage resistance, bending resistance and sealing tests before leaving the factory.

Through these processes, our cables have reliable guarantees for long-term work in the seabed environment.
