Abstract
The invention discloses a zinc-wire-filled corrosion-resisting armour structure for a submarine cable. The armour structure comprises a cable core, an inner liner layer and an outer cover layer in sequence from the inside out. A plurality of steel wires are arranged in a loop manner between the inner liner layer and the outer cover layer, wherein the steel wires are zinc-coated steel wires or alloy-coated steel wires. One zinc wire is arranged in the gap between two adjacent steel wires and the outer cover layer, wherein the diameter of each zinc wire is smaller than that of the steel wire. Anticorrosion pitch is filled in gaps between the steel wires and the inner liner layer as well as the outer cover layer.
Description
Technical field
The invention belongs to submarine cable technical field, specifically corrosion-resistant sheathed structure filled by a kind of submarine cable zinc silk.
Background technology
Submarine cable reliability requirement is high, once after laying, keep in repair very difficult. For preventing the mechanical damage of submarine cable, the sheath of usual submarine cable is constituted by inner liner, thicker wire armouring, serving. Although thicker wire is wrapped on cable; the mechanical damage of outside can be prevented; but these steel wire majorities are zinc-coated wires, and coating is very thin, in production or laid processes, some zinc layers are just damaged; even if being not damaged by; very thin zinc layers also can quickly be corroded in the seawater, losing the protection of zinc layers, steel wire can be subject to sea water directly etching; loses due mechanical protection soon, thus shortening the service life of submarine cable.
Summary of the invention
The present invention provides a kind of submarine cable zinc silk to fill corrosion-resistant sheathed structure, and this sheathed structure corrosion resistance strengthens, thus extending the service life of cable, improves the security reliability of electrical network.
The technical solution used in the present invention is: corrosion-resistant sheathed structure filled by a kind of submarine cable zinc silk, including the cable conductor set gradually from inside to outside, inner liner and serving, some steel wires it are equipped with between described inner liner and serving, adjacent two gaps between steel wire and serving are provided with a zinc silk, the diameter of described zinc silk is less than steel wire, and all gaps between described steel wire and inner liner and serving are filled with anti-corrosion asphalt.
Described steel wire is the steel wire of zinc-coated wire or alloy layer.
The invention have the advantage that owing to the steel wire gap place at zinc-coated wire or alloy layer placed zinc silk, in the seawater, turn between zinc silk and steel wire, form a galvanic element, zinc silk is first subjected to corrosion, owing to zinc filament is long-pending much larger compared with the zinc layers of zinc-coated wire, etching time is long, before zinc silk does not corrode, steel wire will not be corroded, and the anti-corrosion asphalt filled or wrapped serving, the effect of sea water can be stopped again, thus extending the service life of cable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is present configuration schematic diagram.
Wherein, 1, cable conductor, 2, inner liner, 3, steel wire, 4, zinc silk, 5, anti-corrosion asphalt, 6, serving.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is further described, but protection scope of the present invention is not limited to this.
Corrosion-resistant sheathed structure filled by a kind of submarine cable zinc silk, including the cable conductor 1 set gradually from inside to outside, inner liner 2 and serving 6, some steel wires 3 it are equipped with between inner liner 2 and serving 6, wherein, steel wire 3 is the steel wire of zinc-coated wire or alloy layer, gap between adjacent two steel wires 3 and serving 6 is provided with a diameter zinc silk 4 less than steel wire diameter, zinc silk 4 is stranded around wrapping on inner liner 2 together with steel wire 3, and all gaps between steel wire 3 and inner liner 2 and serving 6 are filled with anti-corrosion asphalt 5.
Due to the fact that have employed that there is certain mechanical strength, but the zinc silk that metal activity is stronger than steel wire contacts with armouring wire, in the seawater, turn between zinc silk and steel wire, form a galvanic element, zinc silk is first subjected to corrosion, owing to the zinc filament of unit length is long-pending much larger compared with the zinc layers of zinc-coated wire, etching time is long, before zinc silk does not corrode, steel wire will not be corroded, and the Colophonium filled or wrapped serving, the effect of sea water can be stopped again, thus extending the service life of cable.
Claims (2)
1. corrosion-resistant sheathed structure filled by a submarine cable zinc silk, it is characterized in that: include the cable conductor, inner liner and the serving that set gradually from inside to outside, some steel wires it are equipped with between described inner liner and serving, adjacent two gaps between steel wire and serving are provided with a zinc silk, the diameter of described zinc silk is less than steel wire, and all gaps between described steel wire and inner liner and serving are filled with anti-corrosion asphalt.
