Large-length, high-tensile, small-diameter, high-voltage marine detection cable

Abstract

The invention discloses a high-voltage ocean exploration cable with large length, high tensile resistance and small outer diameter. The high-voltage ocean exploration cable comprises a cable unit, a force-bearing unit, and a first non-woven cloth belt and an outer protective layer which are orderly coated on the cable unit and the force-bearing unit; each of the cable unit and the force-bearing unit is an eccentric structure; the force-bearing unit and the cable unit are independent from each other, and the force-bearing unit is combined and connected with the cable unit according to at least one group of separated eccentric structures; the force-bearing unit comprises at least one group of tensile resistant components, the cable unit comprises a high-voltage insulating core wire and a signal insulating core wire which are stranded to form an inner cable core; and a second non-woven cloth belt is coated on the inner cable core. The cable disclosed by the invention is long in single length, small in outer diameter, large in tensile resistance, high in working voltage, light, convenient and soft in use, resistant in repeated winding, and suitable for repeated retraction and releasing in ocean exploration.

Description

technical field [0001] The invention relates to a cable, in particular to a high-voltage marine detection cable with large length, high tensile strength and small outer diameter. Background technique [0002] With the development of my country's marine industry, military and civilian marine exploration have put forward new special requirements, such as large length, high tensile strength, small outer diameter, high voltage, etc., which are different from existing marine detection cables and are high-tech for special purposes. product. [0003] At present, the common tensile cables can be divided into three types according to the structure. The first type is the self-supporting figure-eight cable: the cable unit and the load-bearing unit form a figure-eight cable section, and the load-bearing unit and the cable unit are completely separated and independent. It is used in various fixed laying occasions such as overhead; the second type is outer covering type: the load-bearing ...

Problems solved by technology

[0003] At present, the common tensile cables can be divided into three types according to the structure. The first type is the self-supporting figure-eight cable: the cable unit and the load-bearing unit form a figure-eight cable section, and the load-bearing unit and the cable unit are completely separated and independent. It is used in various fixed laying occasions such as overhead; the second type is the outer coating type: the load-bearing unit is coated outside the cable unit, such as a steel wire armored cable, which can increase the tensile strength of the cable, but when the cable is stressed, the load-bearing unit The force unit will squeeze the cable core, and the greater the tension, the greater the extrusion force, which will have a certain destructive effect on the cable core. This type of cable is mainly used for laying wells and roadways; the third type is the central load-bearing type: load-bearing The unit is located in the center of the cable, and the cable unit is wrapped around the load-bearing unit. A large amount of filling is required to make the cable round, which will reduce the overall performance of the cable and increase the outer diameter of the cable. When the proper filling is not performed, the cable is rolled repeatedly Axial twisting tends to occur during use, resulting in cable damage or reduced service life
