We need to emphasize a point is, submarine cable project is launched. The current development of submarine cables in China, although the speed of submarine cables in China rapid development, but there is still a gap between developed countries in technology. At present, 500kV submarine cable our application still need to rely on imports. Because the domestic cable manufacturers so far only have the ability to manufacture 220KV photoelectric composite submarine cable. Submarine cable is imported from abroad paper insulation such as Hainan province Qiongzhou Strait network engineering 130 km 500KV, 800mm2 submarine power cable.

In addition to rely on the strong technical support, the development of submarine cable needs billion yuan of the huge capital investment, sophisticated equipment and professional and technical personnel. In addition, the production of submarine cable factory is arranged geographically, requirements must be along the coast, along the river, and have large length of cable products storage facilities and shipping docks. Effect of funds, technology, personnel and environmental factors based on, should have a clear understanding of the enterprise, seek truth from facts, neither blind nor lags behind the development of submarine cables.
