Abstract
The invention discloses a high-temperature resistant fireproof cable with high flexibility. The cable comprises solid or stranded copper conductors in the center of the cable, wherein mica tapes are wound around the copper conductors; and an embossed metal sheath is arranged on the outmost layer. The cable is suitable for the occasions with higher requirements for environmental protection and fireproofing. The cable has the characteristics of fireproofing, explosion-proofing, waterproofing, no smoke, no halogen, no toxicity, high-temperature resistance, strong corrosion resistance, radiation resistance, electromagnetic interference resistance, high current-carrying capacity, strong overload capacity, high flexibility, large-length and large-size production, no need for baking and heating during installation, small bending radius during laying and the like.
Description
Technical field
The present invention relates to a kind of power cable, specifically is a kind of high flexibility fire resistant cable.
Background technology
During breaking out of fire, need people to have adaptability to changes, some people expects at once and will cut off the electricity supply, feel to avoid like this fire to enlarge, actual conditions but are: should not cut off the electricity supply during breaking out of fire, if cut off the electricity supply during breaking out of fire, the road of escape can can't not seen clearly because of illuminating lamp works; If cut off the electricity supply, fire pump can't start, and fire water just is unable to supply; If cut off the electricity supply, fire-fighting rack can't move, and high-rise resident can't escape.
To when breaking out of fire, not cut off the electricity supply, reach purpose of safety again, for distribution line, adopt refractory product, at present, popular fireproof cable mainly contains two kinds on the market: a kind of is to adopt the wrapped and plastic insulation of mica band to combine, the cable of this structure is because the fire-resistant intensity difference of using of refractory material, can be divided into A, B two classes, this structural cable great advantage is soft, and applicable to mobile occasion, refractory temperature can reach more than 950 ℃, cable production length is unrestricted, technology is easily manufactured, and cost is lower, has good humidity resistance, but this cable is owing to adopted plastic insulation, its serviceability temperature grade limited by insulating material serviceability temperature grade.And organic insulating material burns easily, and meeting evolution of heat during burning causes temperature to increase, and leads fire-resistant band carbonization at last, so, the not anti-mechanical oscillation of this cable; Simultaneously, owing to can not use after the organic insulation partial combustion, this cable can only be done disposable use again.The another kind of copper core mineral insulation seamless copper pipe jacket structure that adopts, the advantage of this cable is: owing to adopted full-inorganic thing structure, it is non-veritably combustion cable, again because the temperature resistant grade height of mineral, cable serviceability temperature grade can reach 250 ℃, since adopt the seamless copper pipe sheath, radially waterproof and dampproof veritably.But it is defectiveness also, and at first it is not suitable for mobile occasion, and the in a single day damaged cable insulation of copper pipe will descend rapidly, and breaking point is difficult to look for, so should not adopt in a large number in the engineering, the place that the people is often walked about, can not adopt the magnesium oxide cable, because the epidermis of cable--copper pipe easily breaks; Secondly, the easy moisture absorption of mineral that this cable adopts, so that cable can not be vertically moistureproof, fluid sealant is adopted in the termination, this has had a strong impact on useful life, and joint will guarantee hermetically sealed, this invisible increase difficulty of construction.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, and a kind of high flexibility fire resistant cable is provided.
Technical scheme: the invention discloses a kind of high flexibility fire resistant cable, comprise the solid or twisted copper conductors that is positioned at cable center, the outer wrapped mica bag of copper conductor, outermost layer is provided with the metallic sheath of embossing.
Among the present invention, preferably, described insulating barrier is wrapped mica.With the superior mica bag of fire resistance and insulation property as insulating barrier 2, thereby make cable have high flexibility and good fire resistance properties and environmental-protecting performance.
Among the present invention, preferably, according to different needs, extrude anticorrosion sheath outside metallic sheath, anticorrosion sheath preferably adopts the anticorrosion sheath of low smoke, zero halogen polyolefine material.
Among the present invention, preferably, described metallic sheath is preferably embossing metallic copper or copper alloy sheath, makes cable possess good humidity resistance, environmental-protecting performance, softness and high fire resistance.
The advantage that high flexibility fire resistant cable of the present invention has is: but fire prevention, explosion-proof, waterproof, smokeless, Halogen, nontoxic, high temperature resistant, corrosion resistance strong, radiation hardness, anti-electromagnetic interference, ampacity is big, overload capacity is strong, high flexibility length, specification production greatly, cable need not the baking heating when installing, and characteristics such as the laying installation bending radius is little.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation that increases anticorrosion sheath on the basis of Fig. 1 product.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done further to specify,
As depicted in figs. 1 and 2, the invention discloses a kind of high flexibility fire resistant cable, comprise solid or twisted copper conductors 1 from the inside to the outside respectively, the mica band that fire resistance and insulation property are superior is made wrapped type insulating material 2, the copper of high mechanical properties, and to its metallic sheath 3 that carries out embossing, select according to instructions for use and environment for use, outermost layer can also be selected the anticorrosion sheath 4 of low smoke, zero halogen polyolefine material for use.
The invention provides a kind of thinking and method of high flexibility fire resistant cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each part not clear and definite in the present embodiment is realized.
