Abstract
The invention discloses a flame scouring prevention cable, wherein a plurality of insulated wire cores are twisted into a cable core, and a sheath, a shielding layer, a heat insulation layer and a protection layer are sequentially coated at the outer layer of the cable core; and the heat insulation layer is formed in a way that a plurality of pieces of ceramic fiber cotton are closely arranged and wound at the outer layer of the shielding layer. The flame scouring prevention cable used in an occasion with the scouring of high-temperature flames sprayed by a jet engine repeatedly in a short time is not damaged, and therefore, the service life of the cable is prolonged, the potential safety hazard when the cable is used can be eliminated, and the safety and the reliability when the cable is in work can be ensured.
Description
Technical field:
The present invention relates to a kind of cable, be specifically related to a kind of fire resistant and wash away cable.
Background technology:
Fire resistant is washed away cable and is mainly used the occasion of washing away at the thermal-flame that sprayed by jet engine.Common cable cannot stand washing away of thermal-flame; The thermal-flame that sprayed by jet engine wash away the back oversheath can scaling loss in addition burn, so that feed through to the inner structure of cable, cause cable to scrap, useful life is short; Change frequent; Waste very greatly, hidden danger is very big, is prone to cause systematic failures.Wash away the still normal impregnable cable that uses repeatedly in short-term so seek a kind of fire resistant; Prolong the useful life of cable, avoid the trouble changed repeatedly, reduce unnecessary waste; Topmost is exactly to eliminate the hidden danger that is prone to cause systematic failures, makes cable safe and reliable when work.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide a kind of fire resistant to wash away cable; Use the cable of the occasion of washing away injury-free to solve at the thermal-flame that sprayed by jet engine; Prolong the useful life of cable, eliminate the hidden danger in the cable use, safe and reliable when guaranteeing cable work.
Technical solution problem of the present invention adopts following technical scheme:
Fire resistant is washed away cable, and several insulated wire cores are twisted into cable core, is coated with sheath, screen, thermal insulation layer and protective layer successively at said cable core skin; Said thermal insulation layer by several ceramic fibre cottons at the skin of said screen each other near arranging and being entwined.
Said protective layer is by silica fibrage and apply high temperature resistant adhesive glue and constitute.
Said insulated wire cores by conductor be coated on the outer field insulating barrier of said conductor and constitute.
Compared with present technology, beneficial effect of the present invention is embodied in:
The first, need shielded outer setting thermal insulation layer at cable, require thermal insulation layer to have heat-barrier material high temperature resistant, low heat conductivity character.So thermal insulation layer adopts the material of the cotton material of ceramic fibre, has very high thermal insulation and heat-resisting quantity, can satisfy the required heat-proof quality of cable fully.In order to guarantee cable thermal insulation layer stability of structure when the bending, the insulating layer structure form adopts many ceramic fibre cotton cords peripheral each other near the structure of arranging and being entwined at screen.The main effect of thermal insulation layer is to intercept the outside high heat of most cables, prevents that high heat is to the cable internal sabotage.Can receive the jet thermal-flame that starts to spray in short-term during cable work and be flushed on the cable surface, thermal insulation layer is to be made up of the ceramic fibre cotton material, and is high temperature resistant, and has certain air in the material, can effectively hinder the transmission of heat,
The second, for effect of heat insulation and the stability of structure that guarantees thermal insulation layer, protective layer is set in thermal insulation layer outside, its effect is that the constraint thermal insulation layer prevents to form the effect of heat insulation that produces the slit between the ceramic fibre cotton cord of thermal insulation layer and influence thermal insulation layer.Protective layer adopts quartz fibre to envelope thermal insulation layer through braiding, and bonding in order to prevent that loose its outer surface coating high-temperature plastic of braid from carrying out, the resistance to elevated temperatures of quartz fibre and high-temperature plastic material is consistent with the ceramic fibre cotton material of thermal insulation layer.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Label among the figure: 1 conductor, 2 insulating barriers, 3 sheaths, 4 screens, 5 thermal insulation layers, 6 protective layers.
Below pass through embodiment, and combine accompanying drawing that the present invention is described further.
Embodiment:
Embodiment: referring to Fig. 1, insulated wire cores by conductor 1 be coated on said conductor 1 outer field insulating barrier 2 and constitute.In the middle of the cable for some insulated cores through the stranded cable core that becomes, be coated with sheath 3, screen 4, thermal insulation layer 5 and protective layer 6 successively at the skin of cable core; Said thermal insulation layer 5 by several ceramic fibre cottons at the skin of said screen 4 each other near arranging and being entwined.Said protective layer 6 is by silica fibrage and applies high temperature resistant adhesive glue and constitute.
The design principle of cable of the present invention is: the first, and the main effect of thermal insulation layer 5 is to intercept the outside high heat of most cables, prevents that high heat is to the cable internal sabotage.Can receive the jet thermal-flame that starts to spray in short-term during cable work is flushed on the cable surface; Thermal insulation layer is to be made up of the ceramic fibre cotton material; High temperature resistant; And there is certain air in the material, can effectively hinders the transmission of heat, the destruction that inner insulating barrier 2, sheath 3, the screen 4 of protection thermal insulation layer receives high heat.The second, the effect of protective layer 6 is that the constraint thermal insulation layer makes it keep Stability Analysis of Structures, prevents to form the effect of heat insulation that produces the slit between the ceramic fibre cotton cord of thermal insulation layer and influence thermal insulation layer.Protective layer is to be formed through braiding by quartz fibre, in order to prevent that loose its outer surface of braid from applying high-temperature plastic and carrying out bonding.
