Metal armored cable core technology monopolized by developed countries
"After decades of technological development, the key technologies of metal armor cables have become more mature, but they are all held by foreign companies." Xie Shouhong, chief engineer of Jiangsu Zhongtian Science and Technology Co., Ltd., was held on June 18 in Wuhan. Third National Seabed Optical Cable Communication Technology Symposium and the first session of the National Cable Technology Forum, "published" underwater detection equipment used metal armored cable key technology analysis, "the 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.
After decades of technological development, the key technologies of metal armored cables have become more mature, but they are all held by foreign companies. Foreign manufacturers, such as Nexans, Rochester, JDR, MacArtney, Cortland, Storm and other companies have established sound metal armor cable design, analysis, manufacturing and testing technology theory, to meet the different requirements and different working depth of the metal armor Cable products. Foreign companies have a wealth of practical engineering experience. At present, the maximum application depth of the metal armor cable has reached 10000m. Imported metal armored cables such as "Ocean One" test vessel "Dragon" ROV system and "Ocean VI" comprehensive survey vessel "Sea Lion" ROV system play an important role in marine scientific research in our country.
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.
