The utility model comprises a flame-retardant oversheath of silicon rubber, wherein a metal armoring layer is arranged in the flame-retardant oversheath of silicon rubber. An inner sheath made of tetrafluoroethylene-ethylene copolymer is arranged in the metal armoring layer, and an outer winding cladding made of glass silk tapes is arranged in the inner sheath. A shielding layer with aluminum-plastic composite tapes is arranged in the outer winding cladding, and an inner winding cladding is arranged in the shielding layer with aluminum-plastic composite tapes. At least two pairs of compensating wires mutually stranded are arranged in the inner winding cladding, and a filling layer of glass silk ropes is arranged between the inner winding cladding and the compensating wires. Each compensating wire comprises a polytetrafluoroethylene insulation layer arranged on an outer layer, and a core-wire conductor formed from stranding alloy wires is arranged in the polytetrafluoroethylene insulation layer. The utility model has the advantages of high tensile strength, good shielding performance, favorable fire-retardant effects, good electrical insulation performance, good acid base and oil resistant performance and strong anti-interference ability. The utility model can be used for various temperature measuring places.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of digital compensation cable.
Background technology
Compensating cable be by compensating wire more than two pairs according to a constant pitch pair twist after stranded again stranding, carry out simultaneously split screen or total screen as required, extrude that sheath makes at last again.At present, compensating cable is used extensive day by day in all kinds of electric equipments and auxiliary facility thereof, consumption is also increasing, expansion along with economic development and capital construction specification, the compensating cable use amount that connects between thermocouple and the temperature display meter is doubled and redoubled, and existing compensating cable is because unreasonable structure, make that the various performances of compensating cable are all not ideal enough, its tensile strength is low, shielding is poor, temperature resistant grade is low, electric property, fire resistance and acid-resisting and oil-resisting performance are all relatively poor.
The utility model content
The purpose of this utility model is to overcome the deficiency that common compensating cable exists, and provides that a kind of tensile strength height, shielding are good, good flame retardation effect, electrical insulation properties are good, acid and alkali-resistance, oil resistance are good, the compensating cable of strong anti-interference performance.
The purpose of this utility model is achieved in that the anti-interference digital compensation cable of intrinsic safety type, comprise the flame-proof silicon rubber oversheath, be provided with the metal armouring layer in the oversheath, be provided with the inner sheath of making by tetrafluoroethylene-ethylene copolymer in the armour, be provided with the outer lapping layer of making by glass tape in the inner sheath, be provided with the aluminium-plastic tape screen in the outer lapping layer, be provided with interior lapping layer in the screen, be provided with at least two pairs of mutually stranded compensating wires in the interior lapping layer, be provided with glass fiber rope packed layer between interior lapping layer and the compensating wire; Each compensating wire comprises and is arranged at outer field teflon insulation layer, is provided with in the insulating barrier by the synthetic cored wire conductor of alloy skein silk.
The utility model adopts the synthetic cored wire conductor of alloy skein silk, has guaranteed the flexibility of cable, and simultaneously, its good conductivity can make the temperature measurement accuracy height; Inside and outside two-layer lapping layer not only makes cable easy to process, simultaneously, makes construction of cable compactness, is difficult for loose; Glass fiber rope packed layer, silicon rubber etc. have good fire retardation; Screen has shielding action, and simultaneously, the metal armouring layer also plays certain shielding action, and therefore, its shielding action is good; The metal armouring layer has been strengthened the tensile strength of cable greatly, and the setting of silicon rubber oversheath makes that the cable corrosion resistance is good, acidproof, oil resistant; Therefore, the utility model tensile strength height, shielding are good, good flame retardation effect, electrical insulation properties are good, acid and alkali-resistance, oil resistance are good, strong anti-interference performance; The utility model scope of application is wide, can be applicable to various thermometrics place, has the high advantage of temperature measurement accuracy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 cored wire conductor, 2 insulating barriers, 3 packed layers, 4 interior lapping layers, 5 screens, 6 outer lapping layers, 7 inner sheaths, 8 armours, 9 oversheaths.
Embodiment
As figure, be the anti-interference digital compensation cable of intrinsic safety type, comprise flame-proof silicon rubber oversheath 9, be provided with metal armouring layer 8 in the oversheath 9, be provided with the inner sheath of making by tetrafluoroethylene-ethylene copolymer 7 in the armour 8, be provided with the outer lapping layer of making by glass tape 6 in the inner sheath 7, be provided with aluminium-plastic tape screen 5 in the outer lapping layer 6, lapping layer 4 in being provided with in the screen 5, be provided with two pairs of mutually stranded compensating wires in the interior lapping layer 4, be provided with glass fiber rope packed layer 3 between interior lapping layer 4 and the compensating wire; Each compensating wire comprises and is arranged at outer field teflon insulation layer 2, is provided with in the insulating barrier by the synthetic cored wire conductor 1 of alloy skein silk.
During fabrication, extruding the color separation of teflon insulation layer outside the synthetic cored wire conductor 1 by the alloy skein silk, to pacify a constant pitch again and be twisted into cable, the glass fiber rope is filled, lapping layer 4 in the wrapped one-tenth of glass tape, add aluminium-plastic tape screen 5 then, wrapped again one deck glass tape becomes outer lapping layer 6, extrudes tetrafluoroethylene-ethylene copolymer again and makes inner sheath 7, add armour 8, extrude flame-proof silicon rubber oversheath 9, plastic-aluminum combined Duplication is not less than 25%, and the tinned copper wire textile density is not less than 60%.
Above-mentioned after testing cable has following effect: low electric capacity, and under 800-1000Hz, line is not more than 100PF/Km to mutual capacitance; Anti-interference, the shielding rejection coefficient less than 0.003; High flame retardant, fire-retardant oxygen index are greater than 45; Two-forty observing and controlling, data transmission bauds reach 1200bps/min.Cable also has stronger anticorrosion and ageing resistace, and construction of cable compactness, rounding, safe in utilization can satisfy modernization project fully and use the cable performance requirement in building.
The novel the foregoing description that is not limited to of this use, compensating wire can be how right more than two pairs.
