China's deep sea metal armored cable key technology blank

"Our country has not yet broken through the key technology of metal armored cable and is almost blank in the design, manufacture and testing technology of deep sea metal armored cable." Xie Shuhong, chief engineer of Jiangsu Zhongtian Science and Technology Co., Ltd., was in Wuhan on June 18 Held in the "Third National Submarine Cable Communication Technology Symposium and the first session of the National Cable Technology Forum," published "underwater detection equipment used metal armored cable key technology," paper said.

Xie Shuhong introduced metal sheathed cable underwater detection system is a key component, widely used in ROV, drag body, submarine, CTD underwater sampling equipment, integrated detection of underwater resources and other underwater operations equipment and systems, are dynamic With the integrated functions of power transmission, optical fiber communication, copper communication, remote control command transmission, video image transmission and detection equipment retractable and bearing, it has high tensile strength, flexible bending characteristics, excellent corrosion resistance, Wear-resistant and resistant to repeated retractable and so on.

Metal armored cable belongs to the custom engineering products, high technology, high integration, manufacturing equipment and manufacturing difficult, it is difficult to form a standardized, mass production. For a long time, no matter in our country, it is the cable of new detection equipment or the cable for its operation and maintenance, which basically relies on imports. There are a small number of domestic research units and a low level of supporting technologies. Research on the key technologies such as design, analysis, manufacture, testing and sea test of metal armored cables is still blank. To a certain extent, this also restricts the development of China's marine technological level.

Our country in the metal armored cable research, design, manufacture and testing technology and the international advanced level there is still a big gap. According to the survey and related reports, although a few enterprises in China can provide metal armor cables, the applicable water depth is generally not more than 500m and less demanding on the watertightness of metal armor cables. The key technologies of metal armor cables have not been broken yet and are applicable to the deep sea Of the metal armored cable design, manufacture and testing technology almost blank areas, the domestic use of water depth of more than 500m of metal armored cable all rely on imports.

The conference was co-sponsored by Communications Commission of Communications Society of China, Naval University of Engineering and hosted by the Submarine Cable Communication Technology Research Center of the Chinese People's Liberation Army.
