Description
Technical field
The utility model relates to telecommunication cable technical field, especially a kind of resistance to highly basic is high temperature resistant high roundness submerged cable.
Background technology
Disposable emitter field under water, often can relate to being interconnected of device battery internal control signal, need to use submerged cable, general this equipment is used under water within 600m, during equipment normal shelf, in battery, highly basic (NaOH) is in solid drying state, a cable part directly contacts with highly basic, another part is by being connected to the control device of device battery outside after battery seal ring, after equipment is launched, battery blasthole is commanded to open by control signal, 6MPa seawater enters battery, solid NaOH is dissolved in seawater, form 25%NaOH solution, now the cable of inside battery is immersed in aqueous slkali.
According to above situation, this cable must meet following requirement:
1) cable sheath material and solid NaOH do not react, and preserve within 2 years without the change in any overall dimension or other molecular structures in solid NaOH.
2) cable requires to stand 6MPa seawater pressure by battery seal ring position, do not allow seawater to ooze out along cable and sealing ring gap, simultaneously because sealing ring is circular, therefore cable is round, sealing ring pressurized is more even, and cable surface has not allowed macroscopic stranding lines.
3) can amount of heat be released when highly basic is water-soluble, therefore require cable cover(ing) can high temperature resistant while resistance to highly basic.
4) cable has certain degree of hardness, so require that under 6MPa pressure sheath is without infiltration, distortion and breakage.
5) equipment miscellaneous part size is determined, so require that the outside diameter of cable is necessary for 5.5mm ± 0.1mm.
Above conditional request is very harsh, general conventional polyolefin, elastomer, rubber type of material all cannot meet instructions for use completely, fluoroplastics class performance is only had to reach requirement, fluoroplastics sheathing can only adopt tubular molding tool, mould cannot be utilized to change heart yearn rounding situation, therefore make profile rounding, fluoroplastics jacketed cable without lines, very greatly, conventional subsea cable in the market cannot meet the demands difficulty at all.
Summary of the invention
The purpose of this utility model is exactly can not meet underwater emission equipment use for submerged cable in the market to require this problem, provides a kind of reasonable in design, the resistance to highly basic that serviceability is stable is high temperature resistant high roundness submerged cable.
Concrete scheme of the present utility model is: resistance to highly basic is high temperature resistant high roundness submerged cable, include cable core, described cable core is combined by 4 groups of stranded conductors, the periphery often organizing stranded conductor is enclosed with insulating barrier, the outside of described cable core is surrounded with polytetrafluoroethylene film layer, screen is had in the outer wrap of polytetrafluoroethylene film layer, the outer wrap of screen has sheath, is all filled with packing in the space between described cable core and thin layer, between stranded conductor insulating barrier and insulating barrier.
Stranded conductor described in the utility model forms by the silver-gilt copper wire of 19 0.16mm is stranded.
Insulating barrier described in the utility model and sheath are all extruded by tetrafluoroethylene-perfluoro vinyl alkoxy ether copolymer to form.
Screen described in the utility model is combined by zinc-plated round copper wire.
Packing described in the utility model forms by multiply polyimides filament fiber is stranded.
It is stranded that 19 silver-gilt copper wires in stranded conductor described in the utility model adopt the mode of regular stranded arrangement to carry out arrangement.
Sheath diameter described in the utility model is 5.4mm-5.6mm.
The beneficial effect that the utility model obtains is as follows:
1) due to piece silver-gilt copper wire of 19 in stranded conductor, to adopt a regular mode of crying and arrange to carry out arrangement stranded, effectively improve the pliability of product, and adopt stranded in the same way with one heart and coordinate impacted process, conductor nominal diameter effectively can be reduced to 0.76mm from 0.80mm.
2) because insulating barrier and sheath material adopt tetrafluoroethylene-perfluoro vinyl alkoxy ether copolymer to make, there is better anti-stress cracking performance and higher Long-term service temperature, therefore reliability is better, simultaneously because insulating barrier adopts high-temperature extruder, through extrusion die one-shot forming, adopt conductor 220 DEG C of preheatings, warm water sub-sectional cooling, the adhesive force of insulating barrier is good.
3) packing adopts polyimides filament fiber stranded, and the Long-term service temperature of this material reaches 260 DEG C, consistent with whole cable heatproof, has good tensile strength, and this mode can effectively reduce stranding lines simultaneously.
4) wrapped owing to have employed polytetrafluoroethylene film layer, effectively reduce the lines that stranding brings, ensure that the roundness of finished product.
5) because screen is combined by zinc-plated round copper wire, the electromagnetic interference that battery electric power transmission line produces cable can be eliminated.
6) finished cable has high rounding property, can bear 6MPa hydraulic pressure, do not seep water with sealing ring junction.
The utility model structural design advantages of simple, serviceability is reliable and stable, has good application value.
Accompanying drawing explanation
Fig. 1 is the utility model cross section structure schematic diagram.
In figure: 1-sheath, 2-screen, 3-thin layer, 4-packing, 5-stranded conductor, 6-silver-gilt copper wire, 7-insulating barrier.
Embodiment
See Fig. 1, the utility model is the high temperature resistant high roundness submerged cable of a kind of resistance to highly basic, include cable core, described cable core is combined by 4 groups of stranded conductors 5, the periphery often organizing stranded conductor is enclosed with insulating barrier 7, the outside of described cable core is surrounded with polytetrafluoroethylene film layer 3, screen 2 is had in the outer wrap of polytetrafluoroethylene film layer, the outer wrap of screen has sheath 1, is all filled with packing 4 in the space between described cable core and thin layer, between stranded conductor insulating barrier and insulating barrier.
Stranded conductor described in the present embodiment forms by the silver-gilt copper wire 6 of 19 0.16mm is stranded.
Insulating barrier 7 described in the present embodiment and sheath 1 are all extruded by tetrafluoroethylene-perfluoro vinyl alkoxy ether copolymer to form.
Screen 2 described in the present embodiment is combined by zinc-plated round copper wire.
Packing 4 described in the present embodiment forms by multiply polyimides filament fiber is stranded.
It is stranded that 19 silver-gilt copper wires in stranded conductor described in the present embodiment adopt the mode of regular stranded arrangement to carry out arrangement.
