Description
Technical field
The utility model relates to technical field of electric wires and cables, particularly a kind of quartz fibre insulation superhigh temperature electric wire.
Background technology
Superhigh-temperature cable all adopts inorganic material as cable insulation material in the market.
Mineral insulated cable product structure is copper core copper sheath magnesium oxide insulating cable, mainly power cable, control cables, heating cable and cotton covered wire.Normal operating temperatures is 250 DEG C, and because magnesian fusing point is 2800 DEG C of fusing points far above copper, so actual work temperature can be higher, cable is still reusable through concrete on fire.This product processing technique is complicated, and processing cost is higher, can not realize large produced in lengths.Due to its dielectric constant comparatively large (9.8), the easy moisture absorption, and the low 1-2 of the resistance ratio silicon dioxide order of magnitude when high temperature, so be not suitable as the dielectric of signal-transmitting cable, and production process can not realize the accurate control of electrical performance indexes.
The inorganic insulation superhigh-temperature cable that packs adopts fire-resistant isinglass belt wrapped as high-temperature insulation material; still insulation property can be kept at 800 DEG C; it is one of main material of high temperature-resistant cable; but because its production efficiency is low, control difficulty is large, reliability is low, and mica tape can not bear too high voltage; hardening after high temperature, embrittlement; be easy to powder and come off, lose protective effect, thus affect safe and smooth in the situation such as superhigh temperature, fire of communication, electric power.
Utility model content
The utility model provides a kind of tool quartz fibre insulation superhigh temperature electric wire, on the basis of the bending property keeping electric wire excellent, fire protecting performance, improves the temperature resistant grade of electric wire, product heatproof 800 ~ 1000 DEG C.
The technical solution of the utility model is achieved in that
A kind of quartz fibre insulation superhigh temperature electric wire, comprise insulated wire cores, described insulated wire cores is made up of metallic conductor and wrapped resistant to elevated temperatures quartz fibre insulating barrier outside metallic conductor.
Wherein, preferably, described metallic conductor is nickel wire conductor.
Wherein, preferably, the thickness of described quartz fibre insulating barrier is not more than 1mm.
Wherein, preferably, described insulated wire cores is many.
Wherein, preferably, described insulated wire cores is coated with braiding quartz fibre sheath.
Wherein, preferably, outer jacket is provided with outside described braiding quartz fibre sheath.
Wherein, preferably, described outer jacket is made up of quartz fibre film or band and the wrapped combination of polyimides composite band.
The beneficial effects of the utility model:
Cable of the present utility model is quartz fibre insulation superhigh temperature electric wire, product heatproof 800 ~ 1000 DEG C, the feature such as there is fire prevention, radiation hardness, corrosion resistance is strong, mechanical strength is high, transmission performance is stable, ampacity is large, there are superior bending property, insulation property, though solve mineral insulated cable to improve electric wire temperature resistant grade, can not the difficult problem of produced in lengths greatly.Product is mainly used in military project, iron and steel, Aero-Space, heating furnace, chemical reaction kettle, the field such as in nuclear island of nuclear power station.
