Abstract
A high-temperature-resistant, corrosion-resistant and tension-resistant cable belongs to the technical field of special cables, and comprises a cable core, a shielding layer and an outer sheath. The shielding layer is positioned outside the cable core, the outer sheath is positioned outside the shielding layer, the cable core consists of a conductor, a lead, fillers and a lapping layer, and the lead consists of an outer covering layer covered outside the conductor. The high-temperature-resistant, corrosion-resistant and tension-resistant cable is characterized in that the fillers are made of aramid fibers and enclose the lead, the conductor consists of nickel-chromium alloy wires or nickel-aluminum alloy wires by means of stranding, both the covering layer and the lapping layer are made from polytetrafluoroethylene, and the outer sheath is made of irradiation cross-linked fluorous rubber. The high-temperature-resistant, corrosion-resistant and tension-resistant cable is ideal in tension resistance, excellent in high-temperature resistance, chemical corrosion resistance and radiation resistance, and is environment-friendly.
Description
Technical field
The utility model belongs to the special cable technical field, is specifically related to the anti-Flexible electric cable of a kind of corrosion-and high-temp-resistant, is applied to the occasion such as high-speed electric train, nuclear power facility and hot environment.
Background technology
As high-speed electric train, nuclear power facility and the used cable of hot environment such as high temperature furnace or the like, not only require to have for example anti-performance that deflects of good physical property, but also require to have excellent resistance to chemical corrosion such as heat-resisting, oil resistant and radioresistance or the like, so the cable analogy that people will be used for above-mentioned occasion is high end cable.
The disclosed high temperature ultra-flexible electric cable of China utility model patent Granted publication CN201408572Y sets gradually copper wire mesh braided layer, mica belting layer and cross-linking radiation fluorubber outside cable core, have the strong point of little, the anti-ozone of good tensile strength, resilience and permanent deformation, UV resistant radiation, oil resistant and chemical resistance corrosion.The corrosion-resistant anti-explosion cable of high temperature resistant oil resistant wrapped material outside conductor that CN201440343U recommends is the flame retardant coating (insulating barrier that flame retardant coating is extruded by high temperature resistant high tear-proof silicon rubber) of mica, the double-deck refractory layer of wrapped heat-resisting polytetrafluoroethylene film outside flame retardant coating, provided with shielding layer (tinned copper wire braiding form) outside double-deck refractory layer again, and then outside screen wrapped heat-proof combustion-resistant glass fiber tape, squeeze the cover material material at last and be the corrosion-resistant fluorubber of oil resistant outside fire-retardant glass fiber belt as restrictive coating, the cable that this technical scheme obtained has the good temperature resistance energy undoubtedly, weather-proof and resistance to chemical corrosion.The high-temperature resistant anti-corrosive control cable that CN2414496Y introduces is that the conductor that is insulated layer outside sets gradually lapping layer, flame retardant coating and oversheath outward, can embody the 1st page of last 1 section technique effect of specification.
Above-mentioned prior art has common strong point, promptly has good achievement for corrosion-and high-temp-resistant, but there is common shortcoming, that is exactly that anti-flexibility can not satisfy the instructions for use such as electrified bullet train usefulness power cable that the applicant mentions in the above, and is difficult to satisfy the instructions for use such as automobile starter stube cable, heat-tight machine output cable or the like.Therefore be necessary to be improved, below the technical scheme that will introduce be convenient to based on producing under this prerequisite.
Summary of the invention
Task of the present utility model is to provide a kind of excellent properties that had both had good high temperature resistant, corrosion-resistant and anti-radioactive ray, the anti-Flexible electric cable of corrosion-and high-temp-resistant that has desirable warping strength performance again.
Task of the present utility model is finished like this, the anti-Flexible electric cable of a kind of corrosion-and high-temp-resistant, comprise the screen that cable core is outer with being positioned at cable core and be positioned at the outer oversheath of screen, cable core comprises by conductor and is overlayed on lead, filler and the lapping layer that the outer outer covering layer of conductor constitutes, be characterised in that: described filler is aramid fiber and lead is surrounded, described conductor is by nichrome wire or ni-al alloyed wire is stranded constitutes, described coating and lapping layer are polytetrafluoroethylene, and described oversheath is the cross-linking radiation fluorubber.
In a specific embodiment of the present utility model, described aramid fiber is the aramid fiber through 120 ℃ * 3h dehumidifying.
In another specific embodiment of the present utility model, described polytetrafluoroethylene is the soluble poly tetrafluoroethene.
In another specific embodiment of the present utility model, described screen is made of nickel monofilament or tinned copper wire.
The technical scheme that the utility model provides since just the filler of cable core adopted aramid fiber, thereby have desirable anti-flexibility; Because coating and lapping layer have all been adopted polytetrafluoroethylene (PTFE) and oversheath has been adopted the cross-linking radiation fluorubber, thereby have excellent high temperature resistant, resistance to chemical attack and anti-radioactive ray performance, and have the feature of environmental protection.
Description of drawings
Fig. 1 is example structure figure of the present utility model.
Embodiment
Ask for an interview Fig. 1, Fig. 1 has provided the cross section that constitutes the anti-Flexible electric cable of corrosion-and high-temp-resistant of the present utility model, comprise cable core 1, screen 2 that outside cable core 1, is provided with and the oversheath 3 that is positioned at outside the screen 2, cable core 1 comprises lead 11, filler 12 and lapping layer 13, and lead 11 by conductor 111 and overlayed on the outer outer covering layer 112 of conductor 111 (the industry custom claim line by or outward by), conductor 111 adopts the stranded formation of nichrome wire, also can adopt the stranded formation of ni-al alloyed wire, can also adopt mixing of nichrome wire and ni-al alloyed wire, coating 112 and lapping layer 13 all preferably use PTFE (being polytetrafluoroethylene), and aforesaid filler 12 adopts aramid fiber and lead 11 is surrounded.Before stranding, the aramid fiber silk is dehumidified through dehumidifier, the dehumidifying temperature is 120 ℃, time is preferably 3h, processing like this can make the roundness of the cable behind the stranding excellent in and smooth mirror, and warp resistance (reversing) property ideal, very is suitable for frequent mobile space and uses.For the lapping layer of filling the post of by PTFE 13, after coating that the joint is bonding with double faced adhesive tape.Outside the lapping layer 13 is screen 2, and screen 2 adopts nickel monofilament or tinned copper wire to constitute.Outside the screen 2 is oversheath 3, adopts the cross-linking radiation fluorubber.
The cable that is obtained by the foregoing description can embody the technique effect described in the superincumbent technique effect cable of applicant.
