Abstract
The utility model discloses a mineral-insulated flexible fireproof cable which comprises a cable core, the cable core is formed by stranding a plurality of wire cores, each wire core comprises a conductor, the outside of the conductor is wrapped with a mineral-insulated layer, and the outside of the mineral-insulated layer is wrapped with an insulation protecting layer; the outside of the cable core is wrapped with a metal hydrate stuffing layer; the outside of the metal hydrate stuffing layer is wrapped with a flame retardant belt; and the outside of the flame retardant belt is provided with a protective jacket. The mineral-insulated flexible fireproof cable disclosed by the utility model can satisfy the requirement on resisting fire for three hours under a flame temperature of 950 DEG C through the heat insulation and fire resistance performance of the flame retardant belt and the high-efficiency thermal conductivity of the metal hydrate stuffing layer; and in the mineral-insulated flexible fireproof cable disclosed by the utility model, a metal tube is cancelled structurally, thereby effectively reducing the cost of the mineral-insulated flexible fireproof cable.
Description
Technical field
The utility model relates to the flexible fire-resisting cable of a kind of mineral insulation.
Background technology
In the existing cable; Common fire-resisting cable has been difficult to satisfy the demand in market; Can't reach fire-resistant 3 hours requirement under 950 ℃ of flames on the refractory ability; Though and other metal pipe type mineral insulated cable meets the demands on refractory ability, there is that the program of laying is installed is loaded down with trivial details, some shortcomings such as cost an arm and a leg.
The utility model content
The technical problem that the utility model will solve is that the defective that reduces cost provides a kind of mineral insulation flexible fire-resisting cable for the fire-resisting cable that overcomes prior art can't to be issued to laid processes simple taking into account fire-resistant requirement fire-resistant three hours under 950 ℃ of flames.
The utility model solves above-mentioned technical problem through following technical proposals:
The flexible fire-resisting cable of a kind of mineral insulation, its characteristics are that it comprises: by the stranded cable core that forms of some cores, every said core includes a conductor, and this conductor outer wrap one deck mineral insulation layer is at said mineral insulation layer outerwrap one insulating protective layer; Fill the bed of material at said cable core outerwrap one metal hydrate; Fill the fire-retardant band of bed of material outerwrap one deck at said metal hydrate; Outside said fire-retardant band, be provided with a sheath.
Wherein, this said mineral insulation layer is the mica belt.
Wherein, the said metal hydrate filling bed of material is aluminum hydroxide layer or magnesium hydroxide layer.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is: the high-efficiency heat conduction performance that the flexible fire-resisting cable of the mineral insulation of the utility model is filled the bed of material through the fire insulation heat-proof quality and the metal hydrate of fire-retardant band; Thereby reach fire-resistant three hours requirement under 950 ℃ of flames; And the utility model has structurally been cancelled metal tube, thereby effectively reduces the cost of the flexible fire-resisting cable of mineral insulation.
Description of drawings
Fig. 1 is the cutaway view of the flexible fire-resisting cable of mineral insulation of the utility model one preferred embodiment.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As shown in Figure 1, the flexible fire-resisting cable of the mineral insulation of present embodiment comprises by three stranded cable cores that form of core.Every core includes a bronze medal core conductor 1, at the mica belt 2 of copper core conductor 1 outerwrap one as the mineral insulation layer, at these mica belt 2 outerwrap one deck insulating protective layers 3.
Fill the magnesium hydroxide layer 4 of the bed of material as metal hydrate in cable core outerwrap one.Certainly, also can adopt aluminum hydroxide layer instead of hydrogen magnesium oxide layer, can play conductive force well equally, make the cable temperature inside can't reach the degree of destroying insulation, solve fire-resistant problem well.Outside this magnesium hydroxide layer 4, twine the fire-retardant band 5 of parcel one deck, make flame can't reach on the inner mica belt 2 of cable.Also be provided with a sheath 6 in the outside of fire-retardant band 5.
Insulating protective layer 3 outside the mica belt 2 of the flexible fire-resisting cable of this mineral insulation is similar with common cable, does not use metal tube, thereby has reduced production cost, has simplified installation process.
Though more than described the embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection range of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these execution modes under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection range of the utility model.
Claims (3)
1. the flexible fire-resisting cable of a mineral insulation; It is characterized in that it comprises: by the stranded cable core that forms of some cores, every said core includes a conductor; This conductor outer wrap one deck mineral insulation layer is at said mineral insulation layer outerwrap one insulating protective layer; Fill the bed of material at said cable core outerwrap one metal hydrate; Fill the fire-retardant band of bed of material outerwrap one deck at said metal hydrate; Outside said fire-retardant band, be provided with a sheath.
2. the flexible fire-resisting cable of mineral insulation as claimed in claim 1 is characterized in that said mineral insulation layer is the mica belt.
3. according to claim 1 or claim 2 the flexible fire-resisting cable of mineral insulation is characterized in that it is aluminum hydroxide layer or magnesium hydroxide layer that said metal hydrate is filled the bed of material.
