Undersea four-core oil-filled cable

Abstract

The invention discloses an undersea four-core oil-filled cable which is formed by twisting two insulation line cores, an optical fiber communication cable core and a data line core. A filling layer is arranged at a gap of the cable core. An inner protecting layer, a shielding layer, a water resisting layer, an armor layer and an outer sheath are arranged outside the cable core in sequence. A conductor is of a hollow structure, an oil duct is arranged in the conductor, and a plurality of strengthening cores are arranged at the gap of the cable core after the cable core is twisted. By the undersea four-core oil-filled cable, data transmission and power transmission can be achieved at the same time, the shielding effect is good, the electromagnetic interference resistance capacity is high, the outer diameter of a core wire is small, the level of pressure resistance and the tensile strength are high, high water pressure of deep sea wire distribution of an undersea detecting instrument can be borne, and the working requirements of undersea projects and oil platforms are met. In addition, by the arrangement of the multiple strengthening cores, the cable core of the undersea four-core oil-filled cable is not prone to being broken, and the service life is long.

Description

[0001] technical field [0002] The invention belongs to the field of power cables, in particular to a four-core oil-filled cable for seabeds. Background technique [0003] As people's demand for information in production and life becomes larger and wider, communication technology advances by leaps and bounds, presenting a prosperous scene of information technology in the ascendant. Under the demand of widely adopting information technology in various fields, communication products that are born on demand have sprung up one after another. However, in major equipment such as aerospace, ships, offshore platforms, oil exploration, power plants and other major equipment with large temperature difference between high and low temperatures, high flame retardancy requirements, and strict communication requirements, due to the small demand for communication products, strict quality requirements, and performance factors The requirements are constantly changing due to different occasi...

Problems solved by technology

This type of cable usually has problems such as high cable laying cost and high difficulty factor. In addition, due to the need to lay multiple cables, space is wasted, which has a greater impact on smaller devices; in addition, during the use of cables It is easy to be bent and pulled arbitrarily, and it is easy to cause core breakage
