Abstract
The utility model relates to a six-core balance-type halogen-free flame-retarding environment-friendly sensor cable, comprising fix conductor units, wherein the external side of each conductor unit is wrapped by an insulating layer respectively; and the insulating layers are marked by different colors respectively. The sensor cable is characterized in that the six conductor units are stranded on a filling core; the external sides of the six conductor units are wrapped by aluminium-plastic composite belts; the external side of the aluminium-plastic composite belt is knitted by tinned copper wires; the external side of the tinned copper wire is wrapped by a polyester belt that is internally provided with a tearing rope; and the external side of the polyester belt is coated by a polyurethane sheath. Therefore, the six-core balance-type halogen-free flame-retarding environment-friendly sensor cable has simple structure, can be used safely, has the advantages of being halogen-free, having low smoke and being flame-retarding, oil-resisting, waterproof and flexible, has excellent electric performance and mechanical physical performance, and is particularly suitable for the application of high-end sensor.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, particularly relates to a kind of six core balanced type halogen-free flame-proof environmental protection sensor cables that are used for high-end demand.
Background technology
The moment sensor cable mostly is PVC insulation and sheath with the low side sensor cable at home, these class cable great majority are four-core or six cored structures, the not environmental protection of this kind cable, and stable signal transmission is bad, mutual capacitance between line is also bigger, can't satisfy the high-end market demand.But because the precision of transducer improves constantly, range of application enlarges gradually, and environment for use requires also more and more higher, and this can better the supporting with it use of cable with regard to desirability.
Summary of the invention
The utility model provides a kind of simple in structure, safe in utilization for solving the technical problem that exists in the known technology, has Halogen, low cigarette, fire-retardant, and oil resistant, water-fast, soft six core balanced type halogen-free flame-proof environmental protection sensor cables.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of six core balanced type halogen-free flame-proof environmental protection sensor cables, comprise six roots of sensation conductor element, the every conductor element outside all is enclosed with the insulating barrier of different colours mark, it is characterized in that: described six roots of sensation conductor element is stranded on the filled core, six roots of sensation conductor element outside parcel aluminium-plastic tape, the aluminium-plastic tape outside is woven with tinned wird, and the tinned wird outside is enclosed with polyester belt, be provided with in the polyester belt and tear rope, the outside of polyester belt is enclosed with polyurethane jacket.
The utility model can also adopt following technical measures:
Described insulating barrier adopts polythene material to make.
The core of described six roots of sensation conductor element adopts several bursts of tin-coated copper conductor bundle to close and forms, and filament diameter is 0.10mm～0.15mm.
The described braiding angle that is woven in the tinned wird in the aluminium-plastic tape outside is 65 °～80 °.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, compare with existing cable, have following characteristics: owing to adopt polyethylene insulation, electrical property improves a lot, and insulation resistance rises to the present 1000M Ω km that is not less than from original 10M Ω km; Mutual capacitance also descends a lot, drops to present less than 50nF/km from original 100nF/km.Owing to adopt reasonable structural design, the flexibility of cable also is greatly improved, the environmental resistance of cable has also bigger raising, good resistance to low temperature is arranged, hydrolytic resistance, favorable mechanical physical property (tensile strength and elongation at break) is arranged, wherein tensile strength is brought up to present 20MPa from 12.5MPa, elongation at break is from 150%, brings up to present more than 350%.
In a word, thisly the utlity model has simple in structurely, safe in utilization, have Halogen, low cigarette, fire-retardant, and oil resistant, water-fast, soft, and have good electrical properties and mechanical and physical performance, be particularly suitable for the use of high end sensor.
Description of drawings
