Problems solved by technology

[0003] However, the current submarine power cables in the prior art are all single-core submarine cables, which have the disadvantages of long production cycle, high manufacturing cost, more river bed and road surface occupied during laying, and waste of space. In terms of development, the development of multi-core cables has extremely high technical significance

Embodiment 1

[0020] A long-lasting, solid, high-strength, self-reinforced submarine cable, which is a three-core cable structure as a whole, consisting of three individually wrapped core tubes and an outer protective sheath covering all the core tubes. The outer diameter of the submarine cable is 265mm, and its Each core 1 inside is made of 30 pure copper cores and compressed into a cylindrical core 1 with a diameter of φ38.2mm at a density of 91% using a polycrystalline mold, and the outer surface of each core 1 is covered with PVC Electrostatic coating film 2 made of material; each core tube is provided with a core body 1, an electrostatic coating film 2, an insulating layer 3, a single-core self-fixing water resistance belt 4 and a single-core coating layer 5 from the inside and the outside; the outer layer The protective cover is provided with an inner lining self-fixing water blocking tape 7, an inner lining layer 8, a steel wire armor layer 9, an outer lining self-fixing water blockin...

Embodiment 2

[0036] The whole is consistent with Example 1, the difference is:

[0037] The outer diameter of the submarine cable is 270mm, and each core 1 in it is made of 30 pure copper cores, which are compressed into a cylindrical core 1 with a diameter of φ38.8mm by a polycrystalline mold at a density of 89%. Self-fixing water blocking belt 4, inner lining self-fixing water blocking belt 7 and outer lining self-fixing water blocking belt 10 are all made of indium oxide: tin oxide: calcium oxide: magnesium oxide: iron oxide in a mass ratio of 27:3:1.8: The mixture mixed in the ratio of 1:0.6 is a semiconductor self-curing film that is first cured by NaOH aqueous solution with a mass concentration of 1.5% after being vapor-deposited on the surface of a flat pure copper plate, and then removed from the mold;

[0038] Wherein the manufacture method of semiconductor self-curing film comprises the following steps:

[0039] ① Raw material preparation: prepare indium oxide 270kg, tin oxide 4...

Abstract

The invention discloses a long-term solid-type high-strength and tough self-reinforced submarine cable and a manufacturing method thereof. The submarine cable has a three-core cable structure as a whole, and the outer diameter is 265mm-270mm. Each core tube is provided with a core body from the inside and the outside. , electrostatic coating film, insulating layer, single-core self-consolidating water-blocking tape and single-core sheathing layer; the outer protective cover is provided with inner-lined self-consolidating water-blocking tape, inner lining layer, steel wire armor layer, The outer lining is self-fixing water-blocking tape and the outer lining; the gap between each core tube and the outer protective cover is filled with a solid strip, which is made of epoxy resin and is in the same shape as the core tube and the outer layer protection The sealing strip matched with the sleeve; the single-core sheath layer is a metal casing wrapped with austenitic stainless tape; the inner lining layer and the outer lining layer are made of insulating rubber. The submarine cable of the present invention is self-reinforced in seawater, has high strength, good toughness, puncture resistance, good water resistance, is not easy to bend, has long service life, and resists impact and vibration.

Description

technical field [0001] The invention relates to the field of manufacturing special cables, in particular to a long-term solid high-strength self-reinforcing submarine cable and a manufacturing method thereof. Background technique [0002] Submarine power cables are mainly used to transmit high-power electric energy underwater, which has the same function as underground power cables, but the application occasions and laying methods are different. [0003] However, the current submarine power cables in the prior art are all single-core submarine cables, which have the disadvantages of long production cycle, high manufacturing cost, more river bed and road surface occupied during laying, and waste of space. In terms of development, the development of multi-core cables has extremely high technical significance. [0004] To sum up, there is a need in the market for a submarine cable that is self-reinforced in seawater, has high strength, good toughness, puncture resistance, good...
