Marine Cables: The "Energy Link" for Blue Economy, Backed by Jinyu Cables

I. Marine Cables: A "Necessary Puzzle" for Ocean Development

• Submarine power cables: Undertake the task of power transmission for offshore wind power and island power supply. They need to have characteristics such as seawater corrosion resistance, mechanical tensile resistance, and low insulation loss to ensure stable power transmission in the deep sea.
• Submarine optoelectronic composite cables: Transmit power and signals simultaneously, providing an "electricity + data" integrated solution for marine observation networks and offshore platform communication.
• Umbilical cables: Serve offshore oil and gas development, integrating functions such as power, hydraulics, chemical injection, and signal transmission. They are the "lifeline" of deep - sea oil and gas extraction equipment.

II. Jinyu Cables: The "All - round Supplier" of Marine Cables

1. Technological Breakthroughs: Overcoming Marine Environment Challenges

• Material Innovation: Using ultra - high - purity oxygen - free copper, seawater - resistant cross - linked polyethylene (XLPE) insulation materials, and a double - layer anti - corrosion sheath (such as HDPE + asphalt anti - corrosion layer), the service life of the cable can reach more than 30 years.
• Structural Optimization: Through the "central strength member + multi - layer stranding" design, the cable's tensile and torsion resistance is improved, meeting the strict requirements of deep - sea laying (water depth exceeding 1000 meters) and dynamic platforms (such as FPSO).
• Testing System: Establish an exclusive laboratory for marine cables, simulating environments such as seawater pressure, salt spray corrosion, and extreme temperatures, and controlling product reliability throughout the process.

2. Product Coverage: Meeting All - scenario Needs in One Stop

• Offshore Wind Power: Provide 35kV - 220kV submarine cables, suitable for different installed capacity wind turbines, supporting large - length joint - free production (single - reel length exceeding 5000 meters), reducing offshore construction risks.
• Marine Oil and Gas: Customized umbilical cables, integrating multi - core power, hydraulic channels, and optical fiber units, suitable for deep - water oil and gas field development.
