Wire and cable industry has become a fundamental industry in China's industrial development, from the subdivision of applications, mainly contains power cables, electrical cables, communication cables fiber optic cable sea, submarine cables and feature cables. At present, the market share of power cables and communication cables accounts for a relatively high. However, from the subdivision of the gross margin, due to the impact of factors such as high technical barriers to submarine cables, its gross margin is the highest. With the impact of industrial restructuring and transformation and upgrading development of China's wire and cable industry, submarine cables have become the main competitive direction for domestic strong competitive enterprises.

Wide range of applications, the role of each field is critical

Submarine cable application areas are more extensive, in the submarine observation network, communications, power networks, offshore oil development and offshore wind power fields are more important and extensive applications. In the submarine observation network, various parts of the connection box, sensors, observation instruments and equipment, in addition to a small number of wireless acoustic connection, basically are connected through the submarine cable. In addition, submarine cables are also widely used in communications networks, power networks, offshore oil development, offshore wind power and many other fields.

Optical composite cable advantages, into the future of the main development trend

According to the function, submarine cable can be divided into submarine fiber optic cable, submarine cable, submarine optical composite cable three categories. Among them, the submarine optical composite cable technology content is high, difficult. At the same time, compared to submarine optical cable and submarine cable has a small footprint, superior bending performance, high adaptability with the equipment, scalability, easy construction and other advantages, is the future of the main development trend.
