Abstract
The utility model discloses a fireproof copper-coated magnesium alloy cable which comprises a jacket made of a metal pipe and a cable core arranged in the jacket, the jacket is a corrugate copper-coated aluminum alloy pipe; the cable core comprises a mica tape insulating layer, a plurality of wire cores and alkali-free glass fillers, and the wire cores are arranged in the jacket and are stranded with one another; each of the wire cores is composed of a conductor and an asbestos yarn tape insulating layer; the asbestos yarn tape insulating layer is wrapped outside the conductor; the conductor is composed of a magnesium alloy wire and a copper-coated layer; and the copper-coated layer is wrapped on the outer surface of the magnesium alloy wire. In the utility model, with the adoption of the mica and the asbestos yarn which are very excellent insulating materials and the addition of the alkali-free glass fillers, the cable can constantly remain good insulating property under the circumstance of burning flame, therefore, the property of the cable can be still maintained in the burning flame; the advantages of the copper and magnesium alloy materials can be fully utilized and can be effectively combined, therefore, the copper resource can be saved; and the cable can be widely used in the products such as the power cable, the instrument and meter cable and the like and has good application and dissemination value.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of copper-clad magnesium alloy fireproof cable.
Background technology
Be widely used in the employed cables of industry such as generator, oil, chemical industry, metallurgy high temperature place and sewage disposal at present and all be by cable core and be wrapped in the outer sheath of cable core constituting, this fireproofing of cable is poor, and owing to the reason on making, the length that also is subjected to being made by metal tube limits, therefore any length when cable can't need be accomplished be difficult to satisfy user's user demand.In addition because copper is irreplaceable important source material in the economic development, be widely used in the every field of war industry, electric power, electric, communication, building, light industry, machine-building and communications and transportation.Along with the sustained and rapid development of economy, the copper consumption figure is also increasing substantially, because the copper shortage of resources, people's design when making cable adopts copper clad aluminum conductor to save copper material; Though yet it can reduce the consumption of cable copper, yet in actual production process, because the little natural defect that waits of the little and elongation of copper clad aluminum conductor tensile strength, make its easy fracture in the conductor production process, and can not extensive use.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, provides a kind of fire protecting performance good copper-clad magnesium alloy fireproof cable, it has, and good electric conductivity, conductor resistance rate are little, intensity greatly, advantage such as easy fracture not.
The technical scheme that the utility model adopted is: a kind of copper-clad magnesium alloy fireproof cable, comprise sheath of making by metal tube and the cable core that is positioned at sheath inside, described sheath is the ripple cuprum-cladding-aluminium compo pipe, described cable core comprises mica tape insulating barrier and inner several stranded core and alkali-free glass fillers mutually thereof, described core is made of conductor and wrapped asbestos yarn tape insulation layer in the conductor outside, described conductor is made of magnesium alloy wire and copper clad, and copper clad is wrapped in the magnesium alloy wire outer surface.
As preferably, described core is three.
The beneficial effects of the utility model are: sheath is a bellows soft junction structure in the utility model, makes cable have good bending property, and is easy to use and can make very longly, do not satisfy the needs of different length; Sheath, mica, asbestos yarn all are very excellent insulating material, cooperate the alkali-free glass filler again, can satisfy cable fully and under the situation of flame calcination, continue keep the good insulation performance performance, thereby realizing that cable is in the calcination of flame can also keep its performance; Copper-clad magnesium alloy conductor resistance rate is little, density is little, and intensity is big, good bending property, easy fracture not, in light weight, transportation and construction are convenient in easily welding, alleviate labor strength, make full use of the advantage of copper, magnesium alloy materials,, save the copper resource its effective combination, can be widely used in products such as power cable, instrument and meter cable, the excellent popularization using value is arranged.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, copper clad; 2, mica tape insulating barrier; 3, magnesium alloy wire; 4, alkali-free glass filler; 5, sheath; 6, asbestos yarn tape insulation layer.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of copper-clad magnesium alloy fireproof cable, comprise sheath of making by metal tube 5 and the cable core that is positioned at sheath 5 inside, described sheath 5 is the ripple cuprum-cladding-aluminium compo pipe, described cable core comprises mica tape insulating barrier 2 and inner several stranded core and alkali-free glass fillers 4 mutually thereof, described core is made of conductor and wrapped asbestos yarn tape insulation layer 6 in the conductor outside, and described conductor is made of magnesium alloy wire 3 and copper clad 1, and copper clad 1 is wrapped in magnesium alloy wire 3 outer surfaces.Described core has three.
Claims (2)
1. copper-clad magnesium alloy fireproof cable, comprise the sheath of making by metal tube (5) and be positioned at the inner cable core of sheath (5), it is characterized in that: described sheath (5) is the ripple cuprum-cladding-aluminium compo pipe, described cable core comprises mica tape insulating barrier (2) and inner several stranded core and alkali-free glass fillers (4) mutually thereof, described core is by conductor and wrapped asbestos yarn tape insulation layer (6) formation in the conductor outside, described conductor is made of magnesium alloy wire (3) and copper clad (1), and copper clad (1) is wrapped in magnesium alloy wire (3) outer surface.
