Abstract
The invention relates to a cable manufacturing technology, in particular to a waterproof and corrosion-resistant cable sheath. The high-strength waterproof and corrosion-resistant cable sheath comprises a composite belt wrapped outside a cable core, a sheath layer wrapped outside the composite belt, and steel wires preset in the sheath layer. The cable sheath has low cost, light weight, no pollution and corrosion resistance, can replace the traditional high-strength, waterproof and corrosion-resistant cable sheath, and is used for submarine cables, cables penetrating rivers and lakes and various cables requiring high strength and corrosion resistance.
Description
Technical field
The present invention relates to a kind of cables manufacturing technology, relate in particular to a kind of for waterproof, corrosion cable sheath.
Background technology
Be laid in cable under water, such as submarine cable, pass through the submerged cable in rivers, lake, require during cable laying to bear the mechanical pulling force larger than common cable, cast anchor for preventing after laying, and the mechanical damage of fishing gear, require cable that higher mechanical protection ability and corrosion resistance are arranged, this class cable adopts independently metallic sheath (plumbous cover) waterproof usually, and independently individual layer or double wire armor are strengthened.Lead sheath, armouring wire are in order to prevent oxide etch, the anticorrosion of general coating cable pitch, because the pitch bonding force is poor, intensity is low, cable easily by scratch, descends the Corrosion Protection of cable in production and transportation, uses simultaneously cable pitch, production environment, cable laying environment are relatively poor, laying has in various degree pollution afterwards to surrounding environment, in the higher place of environmental requirement, is subject to certain restrictions.
Summary of the invention
Technique effect of the present invention can overcome defects, and a kind of high-strength waterproof, corrosion cable sheath are provided, and the structural design form that it overturns general cable cover(ing) provides a kind of cleaning, pollution-free, high strength, waterproof, corrosion resistant novel cable sheath.
For achieving the above object, the present invention adopts following technical scheme: it comprises the composite band of cable conductor outside parcel, the outside wrap jacket layer of composite band, steel wire is arranged in the restrictive coating, and steel wire adopts inside and outside two-layer, and composite band and restrictive coating, double-layer wire is melt bonded is integrated, wherein melt bonded mode is: extrude one deck restrictive coating above the composite band, regulate extrusion temperature, composite band and restrictive coating are fused fully, the aluminium or the copper that form a closure are moulded complex waterproof layer; On watertight composition armouring bilayer, pretwist, steel wire is sparsely stranded, be expressed on the armouring wire layer by the high-density polyethylene plastics of extruder with melting again, the armouring wire layer is cast among the high density polyethylene (HDPE) restrictive coating, regulate simultaneously extrusion pressure and melt temperature, the high density polyethylene (HDPE) restrictive coating is also merged with watertight composition, plastic-aluminum or the compound copper-plastics band used of waterproof strengthened the armouring wire of usefulness and the restrictive coating of anticorrosion usefulness and formed a complete composite monolithic like this.
Adopt composite band and restrictive coating welding to consist of watertight composition, have the identical block-water performance of metallic sheath, and lightweight, save metal material.
Steel wire adopts inside and outside two-layer, its pretwist, the structure that is sparsely stranded are easy to and the restrictive coating combination, after the high density polyethylene (HDPE) melting that steel wire is prefabricated among restrictive coating, form a steel and mould mixture, as reinforced concrete structure, the concrete cladding reinforcing steel bar can not only improve the concrete structure performance, and reinforcing bar is wrapped by and not oxidized corrosion simultaneously.In like manner, the steel wire of armouring by prefabricated in the restrictive coating after, isolated steel wire fully and contacted with the direct of surrounding medium, have good decay resistance, and the instructions for use of sheath is satisfied in mixing also for cable cover(ing) provides high tensile force and mechanical strength of steel wire and restrictive coating.
Composite band and restrictive coating, double-layer wire is melt bonded is integrated, and restrictive coating adopts high-density polyethylene material.
The plastic layer of the composite band that cable cover(ing) aluminium of the present invention (copper) is moulded must be the plastics that can merge fully with restrictive coating, composite band is put up vertical wrapping on the cable core of cable, put up the place reliably bonding with hot melt adhesive, then on composite band, extrude one deck restrictive coating, regulate extrusion temperature, composite band and restrictive coating are fused fully, and the aluminium (copper) that forms a closure is moulded complex waterproof layer.
On watertight composition armouring bilayer, pretwist, steel wire is sparsely stranded, be expressed on the armouring wire layer by the high-density polyethylene plastics of extruder with melting again, the armouring wire layer is cast among the high density polyethylene (HDPE) restrictive coating, regulate simultaneously extrusion pressure and melt temperature, it is also merged with watertight composition, plastic-aluminum or the compound copper-plastics band used of waterproof strengthened the armouring wire of usefulness and the restrictive coating of anticorrosion usefulness and formed a complete composite monolithic like this, finishes the preparation of high strength, waterproof, corrosion cable sheath.
Cable cover(ing) cost of the present invention is low, lightweight, pollution-free, corrosion-resistant, and alternative traditional high strength, waterproof, corrosion cable sheath are used for submarine cable, wear the river and cross the lake cable and require high strength, corrosion resistant various cables.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in detail:
Fig. 1 is traditional submarine cable jacket structure schematic diagram;
Fig. 2 is cable cover(ing) structural representation of the present invention.
Embodiment
Cable cover(ing) of the present invention comprises the composite band 2 of cable conductor 1 outside parcel, the outside wrap jacket layer 4 of composite band 2, and steel wire 3 is preset in the restrictive coating 4.
Claims (3)
1. a high-strength waterproof, corrosion cable sheath, it is characterized in that, the composite band that comprises cable conductor outside parcel, the outside wrap jacket layer of composite band, steel wire is arranged in the restrictive coating, steel wire adopts inside and outside two-layer, composite band and restrictive coating, double-layer wire is melt bonded is integrated, and wherein melt bonded mode is: extrude one deck restrictive coating above the composite band, regulate extrusion temperature, composite band and restrictive coating are fused fully, and the aluminium or the copper that form a closure are moulded complex waterproof layer; On watertight composition armouring bilayer, pretwist, steel wire is sparsely stranded, be expressed on the armouring wire layer by the high-density polyethylene plastics of extruder with melting again, the armouring wire layer is cast among the high density polyethylene (HDPE) restrictive coating, regulate simultaneously extrusion pressure and melt temperature, the high density polyethylene (HDPE) restrictive coating is also merged with watertight composition, plastic-aluminum or the compound copper-plastics band used of waterproof strengthened the armouring wire of usefulness and the restrictive coating of anticorrosion usefulness and formed a complete composite monolithic like this.
2. high-strength waterproof according to claim 1, corrosion cable sheath is characterized in that, restrictive coating adopts high-density polyethylene material.
3. high-strength waterproof according to claim 1, corrosion cable sheath is characterized in that, composite band is put up vertical wrapping on the cable core, and the place of putting up bonds with PUR.
