Description
Technical field
The utility model relates to cable, particularly a kind of seabed waterproof cable.
Background technology
At present, the seabed waterproof cable that market uses, mostly is type cable and self-tolerant oil charging cable.This type of cable manufacturing process is complicated, manufacture and maintenance cost high, quality greatly, is transported and lays inconvenience.And sea-floor relief is complicated, bad environments, makes cable very easily impaired.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, provides a kind of seabed waterproof cable.
The utility model for the adopted technical scheme that achieves the above object is: a kind of seabed waterproof cable, comprise external sheath layer and some heart yearns, described heart yearn comprises conductor and insulating barrier, it is characterized in that, be coated with double-sided insulation waterstop outside the insulating barrier of described heart yearn, form the first double-sided insulation water blocking layer; After each heart yearn set, the coated double-sided insulation waterstop again in the outside of wire harness, while forming the second double-sided insulation water blocking layer, makes to leave heat radiation space in wire harness between each heart yearn.
Further, between the conductor of described heart yearn, be filled with the material that blocks water, form the packed layer that blocks water.
Further, be provided with semiconductor waterstop inside the insulating barrier of described heart yearn, this semiconductor waterstop will block water in packed layer and conductor be coated on, and form semiconductive and block water protective layer.
Further, described conductor is that compression type is filled with the material that blocks water.
Further, armour is provided with between the double-sided insulation water blocking layer outside described wire harness and external sheath layer.
Further, described armour is stainless steel sheathed structure.
Further, the insulating barrier of described heart yearn is ethylene propylene diene monomer (EPDM) material layer.
Further, described external sheath layer is ethylene propylene diene monomer (EPDM) material layer.
Further, described heart yearn is more than two.
The utility model has the following advantages: this seabed waterproof cable can be used safely under seabed extremely rugged environment.Formula conductor is pressed in employing, between conductor, increase the material that blocks water, and effectively blocks the diffusion admittance of moisture content between conductor.Increase semiconductor waterstop around conductor, increase the isolation strength of conductor and external source.Before heart yearn set and after set, outside core insulation, increase double-sided insulation waterstop, reinforced insulation and water-resisting ability; And do not increase any filler between heart yearn and core, form heat-dissipating space, during to ensure that electric current passes through cable, can in time heat be distributed.Adopt ethylene propylene diene rubber (EPDM) insulating barrier as core and the external sheath layer of cable that self water proofing property, corrosion resistance and electric property are very excellent.
Above-mentioned is the general introduction of utility model technical scheme, below in conjunction with accompanying drawing and embodiment, is described further the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment;
In figure: 1. conductor; 2. block water material; 3. semiconductor waterstop; 4. insulating barrier; 5. double-sided insulation waterstop; 6. armour; 7. external sheath layer.
Embodiment:
See Fig. 1, the seabed waterproof cable that the present embodiment provides, comprise external sheath layer 7 and three heart yearns, described heart yearn comprises conductor 1 and insulating barrier 4; Be coated with double-sided insulation waterstop 5 outside the insulating barrier 4 of described heart yearn, form the first double-sided insulation water blocking layer; After each heart yearn set, the coated double-sided insulation waterstop 5 again in the outside of wire harness, while forming the second double-sided insulation water blocking layer, makes to leave heat radiation space in wire harness between each heart yearn.A double-sided insulation waterstop 5 is wrapped around the core that each is single, after each core set is good, bag one deck double-sided insulation waterstop 5 again around the wire harness that each core is formed, reinforced insulation and water-resisting ability.When being combined together by heart yearn collection, do not increase any filler, around wire harness after coated double-sided insulation waterstop 5, form heat-dissipating space, during to ensure that electric current passes through cable, can in time heat be distributed.
Be filled with the material 2 that blocks water between the conductor of described heart yearn, form the packed layer that blocks water.Be provided with semiconductor waterstop 3 inside the insulating barrier 4 of described heart yearn, this semiconductor waterstop 3 will block water in packed layer and conductor 1 be coated on, and form semiconductive and block water protective layer.Described conductor 1 is filled with for compression type with the material 2 that blocks water.Formula conductor is pressed in employing, between conductor and the gap of conductor, increase the material that blocks water, and effectively blocks the diffusion admittance of moisture content between conductor; Around conductor, be surrounded by semiconductor waterstop, increase the isolation strength of conductor and external source.
The insulating barrier 4 of described heart yearn is ethylene propylene diene monomer (EPDM) material layer.Adopt ethylene propylene diene rubber (EPDM) as the insulating barrier of core.EPDM is by after sulfuration or cross-linking radiation, mechanical performance is more excellent, and there is excellent weather, resistance to ozone, heat-resisting, cold-resistant, acid and alkali-resistance, corrosion resistance, resistance to water vapour, colour stability, electrical property, oil resistance and normal temperature mobility, can use for a long time in the environment of-40 ~ 120 DEG C by load 200KV high pressure.
Armour 6 is provided with between double-sided insulation water blocking layer outside described wire harness and external sheath layer 7.Described armour 6 is stainless steel sheathed structure.Be added with stainless steel armoring device in the middle of external sheath layer, increase the overall tensile property of cable, meet and cross over remote laying installation requirement.
