Abstract
The invention discloses a high-temperature-resistant cable. The high-temperature-resistant cable comprises a cable core layer, a copper wire wrapped layer, a heat insulation layer and a protective sleeve, wherein a layer of reinforcing pieces is wrapped between the cable core and the wire wrapped layer; the reinforcing pieces are square formed by four isosceles right-angled triangles; the heat insulation layer is aluminum silicate containing mica. The high-temperature-resistant cable is widely applied to the fields of power generation, metallurgy, chemicals and petro-chemicals and the like, not only has excellent high-temperature-resistant fireproof performances, but also has relatively strong cable core firming performance, so that the cable is guaranteed to not deviate from the original set position under normal use and no external force extrusion, and the cable safety is improved.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of high temperature-resistant cable.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable such as used in the field such as generating, metallurgy, chemical petroleum, especially the operational environment of cable is very changeable, and under in real work, cable is often arranged in high temperature and the stronger environment of extraneous extrusion ratio at the scene, the safe handling for main equipment exists very big hidden danger.This just proposes higher requirement to the heat-proof quality of cable and the anti-extrusion performance of core.
Therefore only meet the requirements, could the better fail safe ensureing these field inner cables.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the high temperature-resistant cable that a kind of heat-proof quality is strong, cable core fastness is high.
The present invention takes following technical scheme to realize: a kind of high temperature-resistant cable; it comprises cable core, copper strips belting layer, thermal insulation layer and protective sleeve; one deck reinforcement is wrapped up between described cable core and described belting layer; described reinforcement is the square of four isosceles right triangles composition, described cable core circumference and isosceles triangle three limit tangent.
The present invention has following beneficial effect in sum: the present invention is widely used in the cable that the fields such as generating, metallurgy, chemical petroleum use in hot environment, not only there is excellent fire resistant performance, and there is the firm performance of stronger core, ensure that cable is normally using and being subject to not departing from former desired location under external force extrudes, and improves the fail safe of cable.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, core; 2, reinforcement; 3, copper strips belting layer; 4, thermal insulation layer; 5, rubber protecting jacket.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1; a kind of high temperature-resistant cable; it comprises cable core 1, copper strips belting layer 3, thermal insulation layer 4 and rubber protecting jacket 5, wraps up one deck reinforcement 2 between described cable core 1 and belting layer 3, and described reinforcement 2 is the square of four isosceles right triangle compositions.
As preferred version of the present invention, isosceles triangle three limit of cable core 1 circumference of the present invention and reinforcement 2 is tangent, ensure that cable is normally using and being subject to not departing from former desired location under external force extrudes, and has the firm performance of stronger core, improves the fail safe of cable.
As preferred version of the present invention, thermal insulation layer 4 of the present invention is micaceous alumina silicate.
As preferred version of the present invention, reinforcement 2 of the present invention is ceramic fibre.
This cable allows operational environment maximum temperature to be 100 DEG C.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
