Analysis of Current Status of China's Submarine Cable

In 2012, China’s cable industry’s capacity exceeded that of the United States, becoming the world’s first cable manufacturing country, and nearly 10,000 homes for cables and supporting enterprises. The beautiful billing data shows that the technical content of the cable industry in China is generally low and the technical power is far away. The fact that it lags behind developed countries. Submarine cables There are only a few cable companies in China that can manufacture, but basically do not provide laying services. In contrast, overseas cable companies such as Nexen, ABB and other giants all provide complete solutions for the design, development, production, transportation, laying, maintenance, and supporting facilities of submarine cables. This is the performance of the largest gap. Therefore, in addition to paying attention to cable quality, the development of submarine cable in China should also pay attention to the construction and development of the upstream and downstream extensions of the submarine cable industry chain, and provide customers with complete solutions.

China's submarine cable market is huge and its demand is very strong. How to recover slowly in the global economy, China's cable industry has entered the era of meager profits, and in the increasingly fierce competition in the middle and low end of the cable industry, the industry upgrading of cable companies is being implemented. One of the most realistic issues facing our cable companies. Submarine cables (including fiber optic composites) will become the new profit growth point for enterprises in China's cable industry upgrading. However, from the design and development to the laying of submarine cables, each link will affect the performance of submarine cables, although there are currently several companies in China. Cables of 220kv and below can be manufactured, but their insulation materials, soft joint technology and processes, laying and the like must all rely on foreign companies. Although there are professional installation teams in China, they are basically limited to shallow sea areas. Perfecting the cable industry chain, strengthening the R&D of raw materials, soft joints, etc., and nurturing one's own installation facilities are one of the problems that China's existing submarine cable production capacity companies must solve.

The continuity of submarine cables requires that they minimize the number of soft joints. Therefore, companies with domestic submarine cable production capacity are generally built in areas where waterway transportation is convenient, that is, they can be boarded after the completion of production. Yixing City, Jiangsu Province, China is home to the cable industry in China. There are more than 200 cables and supporting companies, but it is worth noting that in the Yixing area, there are few companies with submarine cable production capacity. There are two inland lakes in Yixing (Xiyuhe East Lake), which leads directly to Taihu Lake, is surrounded by a variety of new developments around the West and East Towers. The author proposes that a submarine cable technology industrial park can be planned around Xiqiao and Dongrong to encourage local enterprises to settle in the Industrial Park. .
