 Technical advantages of submarine cable products: As an important transmission medium in offshore wind power, submarine cables have an important impact on the safety and stability of offshore power transmission. The application environment of submarine cables determines that submarine cables need to have special characteristics such as water resistance, tensile resistance, and corrosion resistance that are superior to land cables, and their technical content is higher. The demand for submarine cables with voltage levels of 220kV and above will increase day by day. With the continuous breakthroughs in wind turbine capacity, the voltage level continues to increase, the transmission capacity becomes larger and larger, and the economic cost continues to decrease. 66kV array cables will be used as the mainstream for wind turbine connection. Products, higher cost performance. With the iterative upgrading of insulation materials for high-voltage submarine cables, core technical barriers have been broken through, which is more conducive to optimizing competitiveness. Innovative technology for submarine cable products: At present, our company's long-length submarine cable 220kV-500 mm2 has a maximum continuous length of about 35 kilometers, and the continuous glue output exceeds 168 tons. It can be continuously started for 28 days, which is a leading level in the industry. Our company can propose plans to expand the current carrying capacity according to the requirements of the bidding documents and combined with the impact of the submarine cable construction environment, such as the transition of copper armor and steel armor, varying diameters of different specifications and other technologies. At the same time, our company is currently compiling scientific research reports such as research and development of supporting technologies for submarine cables and ocean engineering, scientific and technological descriptions and patent applications for new far-reaching submarine high-pressure submarine cable technologies.

 High-voltage cables are a type of power cables that appear with the continuous development of cable technology. High-voltage cables are generally used as the central link in large-scale transmission systems. They are a type of power cables with high technical content and are mainly used for long-distance, large-scale power stations in cities. Power energy transmission. Product advantages: Our company has a 180-meter-high voltage VCV crosslinking production line and has installed a total of 6 world-class imported production lines, including 4 Finnish MAILLEFER-500kV insulation production lines, 1 MAILLEFER-750kV insulation production line and 1 German TROESTER-1000kV insulation production line. The supply of high-voltage cables can be timely and effective, and has the advantages of superior product quality, high production efficiency, and short delivery time.
