Abstract
The invention provides a concentric flame-retardant cable, which consists of an insulated core, a flame-retardant filling strip, a wrapping layer and a cable sheath, wherein metallic hydrate flame-retardant filler containing crystal water is filled in the flame-retardant filling strip, and a grounding layer is arranged outside the wrapping layer. Compared with the prior art, the concentric flame-retardant cable has more stable structure and stronger flame-retardant performance.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of concentric flame-retardant cable.
Background technology
Current, also more and more higher along with the construction of engineering constructions such as subway, tunnel to the cable-flame retardant performance demands, generally all to reach the category-A flame retardant rating.As shown in Figure 1, the five-core flame-retardant cable of present flame retardant cable, especially prior art, overall dimension is big, structural instability, and fire resistance is relatively poor, does not reach high flame retardant rating requirement.
Summary of the invention
The present invention is in order to solve flame retardant cable in the prior art, and big, the structural instability of five-core flame-retardant cable overall dimension does not especially reach the technical problem of high flame retardant class requirement, and a kind of simple, Stability Analysis of Structures, concentric flame-retardant cable that fire resistance is high are provided; By the technical program, make the construction of cable more stable, also reach higher flame retardant rating.
The present invention is for achieving the above object, and the technical scheme that is adopted is: a kind of concentric flame-retardant cable is provided, comprises insulated wire cores, flame-retardant filler, integument and cable cover(ing); Described insulated wire cores is at least one, is filled with flame retardant filler strip between insulated wire cores, and flame-retardant filler is filled in the described flame retardant filler strip; Described integument is wrapped in outside insulated wire cores and the flame retardant filler strip; Be provided with ground plane outside integument, described cable cover(ing) is wrapped in outside the described ground plane.
Further, described ground plane is a linear structure, and the ground plane of linear structure is wrapped in outside the integument.
Further, described flame retardant filler strip comprises a plastic layer, and described flame-retardant filler is filled in the described plastic layer.
Further, described flame-retardant filler is the metal hydrate that contains the crystallization water.
Further, described insulated wire cores is three or four.
The present invention compared with prior art, its effect is actively and significantly.Among the present invention,, increased the function of shielding of cable the ground plane in the ground connection core alternative costs technical scheme in the prior art flame retardant cable; Five cored structures of prior art are changed into quadrature arrangement, make the construction of cable more stable, simultaneously cable dimension is reduced to some extent; And the flame-retardant filler that filling is made of metal hydrate between insulated wire cores, when cable is met fire, the flame retardant filler strip outer plastic layer is broken, the metal hydrate flame-retardant filler decomposes that contains the crystallization water in the plastic layer goes out the crystallization water, stop the burning of cable, greatly improved the fire resistance of cable.
Description of drawings
Fig. 1 is the structural representation of prior art flame retardant cable.
Fig. 2 is the structural representation of concentric flame-retardant cable of the present invention.
Embodiment
The present invention is described further below in conjunction with accompanying drawing.
As shown in Figure 1, prior art flame retardant cable structural representation, it comprises core, flame-retardant filler 2 and cable cover(ing) 3; Core comprises insulated wire cores 1 and ground connection core 4; Flame-retardant filler 2 is filled between insulated wire cores 1, ground connection core 4 and the cable cover(ing) 3.The flame retardant cable of prior art structure is structural instability on the one hand, and fire resistance is also relatively poor.
As shown in Figure 2, concentric flame-retardant cable structural representation of the present invention, it comprises insulated wire cores 1, integument 6, cable cover(ing) 3; Be outside equipped with ground plane 5 at integument 6, cable cover(ing) 3 is wrapped in outside the ground plane 5; Ground plane 5 is a linear structure, can be copper wire, and is wrapped in outside the integument 6; Be filled with flame retardant filler strip 7 between the insulated wire cores 1, flame retardant filler strip 7 comprises a plastic layer, and flame-retardant filler 2 is filled in the plastic layer of flame retardant filler strip 7; Flame-retardant filler 2 is made of the metal hydrate that contains the crystallization water.
By the ground plane 5 of this flame retardant cable, increased the function of shielding of cable; This flame retardant cable is a quadrature arrangement, and more more stable than prior art five cored structures, cable dimension also reduces to some extent; When cable was met fire, the plastic layer of flame retardant filler strip 7 outsides broke, and flame-retardant filler 2 decomposes that contain the crystallization water in the plastic layer go out the crystallization water, have stoped the burning of cable, have greatly improved the fire resistance of cable.
Claims (5)
