Deep sea cable

Abstract

The invention discloses a deep sea cable, which belongs to the technical field of cables. The deep sea cable comprises a cable core bundle consisting of a plurality of cable cores, wherein each cablecore is twisted by using three stands of high-strength high-modulus polyethylene fibers; and an outer coverage layer woven by 32 stands of high-strength polyamide multifilament is arranged on the periphery of the cable core bundle. The excellent wear and corrosion resistance of the high-strength polyamide multifilament ensures the excellent wear-resistance, sea water corrosion-resistance and ultraviolet radiation-resistance performance of the whole cable; the ultra high strength of the high-strength high-modulus polyethylene fibers increases the tensile strength of the cable and meets the requirements on ultra high strength of the deep sea cable; and the cable cores can be manufactured by a multi-length small-diameter connector-free ultra-long process that ensures that the whole cable is made long enough, avoids connectors and meets the requirements on the ultra high strength of the deep sea cable. The deep sea cable is high in strength, light in weight, wear resistant and corrosion resistant and can be applied to off-shore operation, in particular to oil exploration platforms.

Description

technical field [0001] The invention relates to a cable, in particular to a cable used by an oil drilling platform. Background technique [0002] As an important strategic resource, oil has been valued more and more by many countries. With the depletion of land resources, everyone is looking at the deep sea, so deep sea oil exploration must be carried out. [0003] In recent years, with the continuous improvement of my country's economic strength and the long-term strategic demand for oil, our country has also put the development and exploitation of deep-sea oil fields in a very important position. [0004] During the exploration of deep-sea oilfields, the oil exploration drilling platform needs to be moved frequently, which must be achieved with the help of deep-sea cable towing. At the same time, during the exploration process, the drilling platform must be fixed with cables, and this The cable must have super high strength and super long length. Generally, the length of ...
